Ten sections. One practice brief.

Q: Were the guitarist facts on this page checked?

The specific, checkable claims (Django Reinhardt's fretting-hand injury, Wes Montgomery's thumb technique, Tony Iommi's prosthetic fingertips, Albert King's reversed-strung guitar, Jimi Hendrix's restrung Stratocaster, Eddie Van Halen's tapping, B.B. King's \u201cLucille\u201d, Robert Fripp's tape looping, Kevin Shields' tremolo-arm technique, and Michael Hedges' percussive harmonics) were independently checked against named sources before publishing. The remaining entries use general, well-established era/genre/technique characterisation rather than unverified specifics — see the Sources section for details.

52 string actions, 42 effects, a 15-level tone spectrum, setup references, 18 style templates, 50 players, 50 duet roles, 90 rhythm-section patterns and 100 genres. Select anything that applies to tonight's practice — the panel fixed to the bottom of the screen composes your choices into one plain-text brief you can copy, download or read straight off the phone.

01 — String Actions

52 techniques, catalogued.

Every way a right or left hand can set a string moving, grouped into nine families. Tap a row to add it to your practice brief — category is always shown by symbol and border, never by colour alone, so it reads the same in print or to a colour-blind eye.

52 string-action techniques with category, description, intensity and character; select rows to add to the practice brief

Alternate Picking	Picking	Strict down-up-down-up motion on every note, the backbone stroke most other picking approaches are measured against.	Medium	even, mechanical, fast
Economy Picking	Picking	The pick takes the shortest physical path across strings, continuing in one direction when a string change and a stroke change line up.	Medium	flowing, efficient
Sweep Picking	Picking	One continuous stroke brushes across several adjacent strings in the same direction to outline an arpeggio shape.	Heavy	cascading, fluid, dramatic
Hybrid Picking	Picking	The pick covers the lower strings while the middle and ring fingers pluck the higher ones in the same phrase, letting non-adjacent strings speak together.	Medium	snappy, layered
Tremolo Picking	Picking	Extremely fast, continuous alternate picking on a single note or dyad, used to sustain intensity where a held note would fade.	Heavy	relentless, buzzing, urgent
Down-Picking	Picking	Every note struck with a downstroke only, trading speed ceiling for rhythmic weight and uniform attack.	Heavy	punishing, locked, heavy
Fingerstyle	Finger	Strings plucked directly by the bare fingertips or nails with no pick at all, giving each finger an independent voice.	Light	warm, intimate, textured
Thumb-Lead Picking	Finger	The picking-hand thumb strikes the strings in place of a pick, trading top-end snap for a rounder, fleshier attack.	Light	mellow, rounded, horn-like
Claw-Hand Hybrid	Finger	The thumb keeps an independent, steady bass pulse on the low strings while the fingers pick out a melody on top at the same time.	Medium	self-accompanying, busy
PIMA Pattern	Finger	Classical right-hand assignment where thumb, index, middle and ring each own a string group, keeping arpeggios evenly voiced.	Light	orderly, classical, even
Chicken Pickin'	Finger	Muted, hybrid-picked notes are snapped against open, ringing ones for a percussive, twangy country-and-funk attack.	Medium	twangy, percussive, snappy
Travis Picking	Finger	An alternating-thumb bass line rocks between two bass strings while the fingers pick out a melody on top, a folk and country staple.	Light	rolling, self-contained
Palm Muting	Muting	The picking-hand palm rests lightly on the strings just in front of the bridge, shortening sustain into a tight, percussive thud.	Medium	tight, percussive, controlled
Fretting-Hand Muting	Muting	Fretting-hand fingers lay lightly across unused strings so they can't ring if the pick brushes them.	Light	clean, quiet, disciplined
Chugging	Muting	Tight palm muting on the low strings driven at high gain, the core rhythmic figure of metal and djent riffing.	Heavy	mechanical, percussive, low
Dead-Note Percussion	Muting	Strings are fretted just enough to kill their pitch entirely and struck for a pitchless, percussive click used as a rhythmic placeholder.	Medium	clicky, rhythmic, pitchless
Cross-Hand Muting	Muting	The picking hand mutes strings that aren't currently in use between chord changes, cleaning up the transition.	Light	tidy, transitional
Post-Strum Dampening	Muting	The strumming hand lands back on the strings immediately after a strum, cutting the chord's sustain short on purpose.	Medium	clipped, staccato
Hammer-On	Legato	A fretting finger strikes down onto a higher fret hard enough to sound the note without a new pick stroke.	Light	smooth, connected
Pull-Off	Legato	A fretting finger flicks off the string toward the floor to sound a lower fretted note or an open string.	Light	smooth, connected
Legato Run	Legato	A chain of hammer-ons and pull-offs across a scale shape driven by a single pick attack at the start.	Medium	liquid, fast, slurred
Slur-Into-Bend	Legato	A hammer-on or pull-off lands directly into a bend rather than a static note, joining two techniques into one gesture.	Medium	vocal, connected
Tapped Legato Phrase	Legato	A hammer-on/pull-off run is extended upward by adding a picking-hand tap as an extra, higher 'finger'.	Heavy	extended, virtuosic
Cross-String Legato	Legato	A legato phrase hops to an adjacent string mid-run without a new pick stroke, using the momentum of the previous slur.	Medium	flowing, seamless
Bend	Pitch	The fretting hand pushes or pulls a string sideways to raise its pitch smoothly up to a target note.	Medium	vocal, expressive
Pre-Bend and Release	Pitch	The string is bent up to pitch silently before it's picked, then released back down while ringing.	Medium	sighing, vocal
Finger Vibrato	Pitch	Small, repeated bend-and-release cycles around a fretted note, the guitar's equivalent of a singer's vibrato.	Light	singing, warm
Bar Vibrato	Pitch	A vibrato or whammy bar wobbles the whole string set's pitch up and down around a chord or note.	Medium	wavering, wide
Unison Bend	Pitch	A note bent up on one string is matched in pitch against the same note fretted straight on the string above.	Medium	piercing, bright
Microtonal Bend	Pitch	A bend stopped deliberately short of a full fret-step, landing on an in-between 'blue' pitch rather than a named note.	Light	bluesy, unresolved
Slide (Glissando)	Slide	A fretted note is carried to another fret without releasing finger pressure, sounding every pitch in between.	Light	smooth, connective
Slide Guitar	Slide	A bottleneck or bar worn on a finger glides freely over the strings, removing the fret grid entirely for continuously variable pitch.	Medium	vocal, fretless, keening
Slide-In From Below	Slide	The target note is approached from a lower fret in one continuous motion that arrives just as the note is meant to land.	Light	scooped, casual
Slide-Out	Slide	A note is left by sliding off the end of the neck or fading into an unfretted silence rather than stopping cleanly.	Light	trailing, loose
Pedal-Steel-Style Bend-Slide	Slide	A slide is combined with a simultaneous bend on a different string to mimic a pedal-steel's compound pitch movement.	Medium	pedal-steel, swooping
Portamento Run	Slide	A fast slide connects two distant notes inside an otherwise legato line, smearing the space between them on purpose.	Medium	swooping, dramatic
Natural Harmonic	Harmonic	A finger touches a string exactly over a fret division (commonly the 12th, 7th or 5th) and lifts the instant the string is picked, isolating an overtone.	Light	bell-like, pure
Pinch Harmonic	Harmonic	The picking-hand thumb grazes the string a fraction of a second after the pick strikes it, forcing a high overtone to squeal out.	Heavy	squealing, aggressive
Tapped Harmonic	Harmonic	The picking hand taps the string an exact fret-division above a note that's already fretted, sounding that note's harmonic instead of its fundamental.	Medium	chiming, precise
Harp Harmonic	Harmonic	Natural or pinch harmonics are picked out note-by-note inside a fretted chord or line, so fretted and harmonic pitches ring together.	Medium	cascading, harp-like
Volume-Swell Harmonic	Harmonic	A harmonic is sounded with the volume rolled to zero, then faded up with a pedal or volume knob so the pick attack disappears entirely.	Light	swelling, ambient
Behind-the-Nut Harmonic	Harmonic	Plucking the short, usually-ignored length of string between the nut and the tuning peg produces a thin, high, out-of-scale pitch.	Light	glassy, alien
String Slap	Percussive	The thumb slaps a string down against the fretboard, borrowed from bass technique, for a percussive low-end thump.	Heavy	thumping, funky
Body Percussion	Percussive	The guitar's top, sides or scratch-plate are tapped or slapped by hand to add a drum-like layer independent of the strings.	Medium	rhythmic, drum-like
Muted Scratch	Percussive	The pick or fingers scrape rhythmically across fully muted strings, producing rhythm without any definite pitch.	Light	scratchy, rhythmic
Pick Scrape	Percussive	The edge of the pick is dragged down a wound string, tracing its ribbing for a rasping, rising zip.	Medium	rasping, abrasive
Palm-Slap Punch	Percussive	The picking-hand palm slaps flat across the strings for one short, percussive chord stab with almost no sustain.	Heavy	stabbing, blunt
Prepared Guitar	Experimental	Small objects (bulldog clips, coins, an e-bow, cutlery) are placed on or between the strings before playing to change their timbre.	Medium	rattling, unpredictable
E-Bow Sustain	Experimental	A handheld electromagnetic driver held over a single string vibrates it directly and indefinitely, without ever picking it.	Light	violin-like, endless
Bowed Guitar	Experimental	A violin or cello bow is drawn across the strings instead of picking them, producing a sustained, non-plucked tone the instrument can't make any other way.	Medium	eerie, sustained
Two-Hand Tapping Chords	Experimental	Both hands tap full chord shapes onto the fretboard at once, sounding harmony that a single fretting hand couldn't reach alone.	Heavy	percussive, orchestral
Scordatura Exploration	Experimental	One or more strings are deliberately mistuned away from any standard reference, opening interval shapes and open-string drones that don't exist in normal tuning.	Medium	disorienting, exploratory

Selected techniques feed the practice brief below: an action×effect pairing note is added once you also pick an effect in section 03.

Technique & Architecture Cross-Reference

Seven functional families, not mechanical ones.

The nine categories above group techniques by how you physically produce them. This second lens groups them by what structural job they do in a piece — folded in to cover ground the category list alone doesn't reach, and feeding the arrangement-arc line in your practice brief.

Attack Architecture

How a note begins: pick, finger, thumb or tap striking the string.

Draws mainly on: Picking, Finger, Harmonic

Sustain Architecture

How a note is extended once struck: vibrato, e-bow, bowing, feedback.

Draws mainly on: Legato, Pitch, Experimental

Rhythmic Architecture

How technique itself creates pulse: muting, chugging, percussive hits.

Draws mainly on: Muting, Percussive

Harmonic Architecture

How technique connects or colors pitch relationships: slides, harmonics, bends.

Draws mainly on: Slide, Harmonic, Pitch

Timbral Architecture

How technique changes tone color independent of pitch or rhythm: harmonics, scrapes, prepared strings.

Draws mainly on: Harmonic, Percussive, Experimental

Dynamic Architecture

How technique shapes loud-to-soft control: finger pressure, pick force, volume swells.

Draws mainly on: Finger, Pitch, Harmonic

Spatial Architecture

How technique interacts with effects and room: feedback, e-bow, bowed sustain feeding reverb/delay.

Draws mainly on: Experimental, Harmonic

Rhythm architecture (pick one, optional)

Ostinato-based — one fixed pattern repeats as the structural spine.
Call-and-response — phrases alternate between two rhythmic ideas or players.
Metric modulation — the felt pulse shifts while the actual tempo stays constant.
Additive meter — bars are built from uneven groups (2+2+3, 3+3+2).
Polymetric layering — parts of different bar lengths phase in and out of alignment.
Groove-locked — every part subordinates to one shared, steady pocket.
Free-time — rhythm is not fixed to a steady pulse at all.

Melody architecture (pick one, optional)

Motivic development — a short idea is varied, extended and transformed over time.
Call-and-response phrasing — melodic phrases answer one another like a conversation.
Modal center — melody orbits a fixed scale/mode rather than functional chord changes.
Chromatic tension-release — melody deliberately steps outside the key before resolving.
Drone-based — melody unfolds over a fixed, unmoving pitch center.
Sequence/repetition — a melodic shape repeats at different pitch levels.
Through-composed — melody develops continuously without repeating a fixed structure.

02 — Setup & Signal

Where the signal actually goes.

The conventional order pedals sit in, then two reference tables: instrument configuration and amp/cab/mic pairing. Pick one of each to anchor your practice brief.

Instrument

String vibration is converted to a raw electrical signal by the pickups.

Gain stage

Overdrive, distortion or fuzz shapes how hard the waveform clips before anything else touches it.

Modulation stage

Chorus, phaser, flanger, tremolo or pitch effects vary conventionally placed after gain so they modulate an already-shaped tone.

Time stage

Delay and reverb are typically placed last among pedals so echoes and reflections repeat the finished, already-driven tone.

Preamp

The amplifier's own front end applies further gain and its tone-stack EQ.

Power amp

Drives the signal up to speaker level; on tube amps, pushing this stage hard adds its own, different-feeling compression from the preamp.

Speaker cabinet

Speaker size, count and voicing shape the frequency response before any sound reaches the room.

Microphone / capture

Microphone choice, distance and position across the speaker cone select which part of that cabinet's sound is recorded or reinforced.

Instrument

Ten instrument configurations with body, pickups, position, tuning and string gauge

Superstrat, HH humbuckers	Bolt-on solidbody, contoured	Dual humbucker	Bridge	Drop D	10-46
Offset, single-coil	Solidbody, offset waist	Single-coil x3	Neck/middle blend	Standard E	9-42
Semi-hollow, humbucker	Semi-hollow with center block	Dual humbucker	Neck	Standard E	10-46
7-string, extended range	Bolt-on or neck-through solidbody	Passive humbucker	Bridge	Drop A	10-59
8-string, extended range	Neck-through solidbody, longer scale	Passive/active humbucker	Bridge	Drop E (low)	9-65 (8-string set)
Baritone	Solidbody, extended scale length	Dual humbucker	Bridge	B standard	13-62
Archtop hollowbody	Full hollowbody, carved or laminate top	Floating or single humbucker	Neck	Standard E	11-50
12-string	Solidbody or dreadnought acoustic	Single-coil or piezo	Neck/bridge blend	Standard E (courses)	10-46 (12-string set)
Nylon-string classical	Full hollowbody, fan-braced top	None or under-saddle piezo	Acoustic (no pickup position)	Standard E	Nylon/composite, normal tension
Resonator / slide	Metal or wood body with resonator cone	None or magnetic add-on	Bridge (cone-coupled)	Open G or Open D	12-54, heavy

Amp, Cab & Mic

Eight amp, cabinet and microphone pairings with placement notes

Blackface-style clean combo	1x12 or 2x12 open-back	Dynamic cardioid at the cone edge	Headroom-first, stays clean at volume; mic just off-axis to tame fizz.
British-voiced plexi-style head	4x12 closed-back, greenback-style	Dynamic cardioid at the cone edge	Mid-forward breakup; classic rock rhythm and lead territory.
High-gain modern head	4x12 closed-back, V30-style	Dynamic cardioid at the cone edge, close	Tight low end for palm-muted rhythm; close mic keeps the attack forward.
Boutique low-wattage tube combo	1x12 open-back	Small-diaphragm condenser, further back	Amp saturates at bedroom volume; roomier mic placement captures cabinet + air.
Modeler / profiler (direct)	Impulse response, closed-back voicing	Simulated close dynamic, digitally	No physical room; IR choice replaces mic choice entirely.
Bass-forward doom/stoner half-stack	4x12 closed-back, vintage-voiced	Dynamic cardioid, off-axis toward cone edge	Low end left in rather than tightened; off-axis mic avoids boom buildup.
Twin-channel versatile head	2x12 closed-back	Ribbon mic, center of cone	Ribbon smooths high-gain fizz; centered position for maximum midrange bite.
Acoustic-electric preamp/DI	No cabinet (direct)	Small-diaphragm condenser on the soundhole/body, optional	Blend of DI signal with a body mic keeps both clarity and room tone.

03 — Effects & Space

42 effects, three families.

Gain shapes the waveform, modulation moves it, time repeats or spatialises it — the order this page lists them in is also the order they're conventionally chained. Select any to pair against your chosen techniques.

42 effects with category, mechanism and sonic character; select to add to the practice brief

Clean Boost	Gain	Raises signal level ahead of the amp without adding audible clipping of its own.	louder, unchanged shape
Overdrive	Gain	A soft-clipping circuit rounds off the peaks of the waveform, emulating a tube amp being pushed hard at low volume.	warm, touch-sensitive breakup
Distortion	Gain	A harder clipping circuit flattens the waveform further than overdrive, adding more harmonic content and compression.	thick, saturated, compressed
Fuzz	Gain	Heavy clipping pushes the waveform toward a near-square wave, historically via germanium or silicon transistors.	buzzing, ragged, thick
Treble Booster	Gain	A narrow boost centered on the high-mid frequencies, originally built to drive the front end of a low-headroom amp.	cutting, bright, aggressive
Bit-Crusher	Gain	Digitally reduces sample rate and/or bit depth, introducing quantization artifacts instead of analog clipping.	gritty, lo-fi, digital
Octave Fuzz	Gain	A fuzz circuit combined with a tracking octave-up or octave-down pitch circuit.	synth-like, buzzy, doubled
Tube-Screamer-Style Overdrive	Gain	A mid-hump overdrive that shapes the signal before it reaches an already-driven amp, rather than replacing the amp's own gain.	focused, mid-forward push
Noise Gate	Gain	Mutes the signal automatically once it falls below a set threshold, silencing hiss and hum between notes.	silent, clinical
Compressor	Gain	Automatically reduces the level of loud peaks and/or raises quiet passages, narrowing the dynamic range.	even, sustained, controlled
Parametric EQ Pedal	Gain	Boosts or cuts chosen frequency bands before or after the gain stage to reshape the tone directly.	surgical, corrective
Preamp Pedal	Gain	Emulates an amplifier's front end (tone stack and gain stage) in pedal form for use direct or into a clean power amp.	amp-like, foundational
Expander/Gate Combo	Gain	A noise gate with a variable ratio rather than a hard on/off threshold, for more transparent cleanup.	clean, transparent
Harmonic Exciter	Gain	Synthesizes new upper harmonics related to the input signal and blends them back in to increase perceived clarity.	airy, present, bright
Chorus	Modulation	Mixes the dry signal with one or more pitch-modulated, delayed copies of itself, simulating several instruments playing the same part.	thick, shimmering, wide
Flanger	Modulation	A very short, modulated delay is mixed back with the dry signal, creating a moving comb-filter sweep.	jet-like, sweeping, metallic
Phaser	Modulation	Modulated all-pass filter stages shift phase across the spectrum, creating moving notches when summed with the dry signal.	swirling, spinning
Tremolo	Modulation	An oscillator rhythmically raises and lowers the signal's volume.	pulsing, rhythmic
Pitch Vibrato (Pedal)	Modulation	An oscillator rhythmically raises and lowers the signal's pitch rather than its volume.	wavering, seasick
Rotary Speaker Simulator	Modulation	Digitally or electromechanically emulates a spinning speaker cabinet's combined Doppler pitch shift and volume swirl.	swirling, organ-like
Uni-Vibe	Modulation	A four-stage phase-shift circuit originally built to approximate a rotary speaker with photocells and lamps.	watery, throbbing
Ring Modulator	Modulation	Multiplies the input signal by an internal oscillator, producing new sum-and-difference frequencies unrelated to the original harmonic series.	clangorous, bell-like, inharmonic
Envelope Filter	Modulation	A band-pass filter whose center frequency is driven by the input signal's own picking dynamics rather than a fixed clock.	funky, quacking, responsive
Wah	Modulation	A sweepable band-pass filter controlled in real time by a foot treadle.	vocal, sweeping
Pitch Shifter	Modulation	Tracks the input pitch and outputs it transposed by a fixed, chosen interval in real time.	harmonized, synthetic
Harmonizer	Modulation	Adds one or more pitch-shifted voices at a chosen harmony interval above or below the dry note, following the input's key.	lush, choir-like
Whammy-Style Pedal	Modulation	A treadle-controlled pitch shifter, typically used for dramatic dive-bombs or sustained interval leaps.	dramatic, dive-bombing
Detune/Doubler	Modulation	Mixes the dry signal with a copy shifted by only a few cents, simulating a second, imperfectly-tuned take.	thick, subtly wide
Analog Delay	Time	A bucket-brigade device passes the signal through a chain of capacitors, repeating it with a warm, filtered decay.	warm, degrading repeats
Digital Delay	Time	Samples the signal and plays it back after a set time in the digital domain.	clean, precise repeats
Tape Echo	Time	A physical tape loop records and immediately replays the signal off a second head, adding pitch wobble and saturation with each pass.	wobbly, saturated, organic
Spring Reverb	Time	A transducer mechanically vibrates a suspended metal spring; a pickup at the far end captures the decaying resonance.	boingy, small-room
Plate Reverb	Time	A large suspended metal plate is excited by a transducer and its dense vibration is picked up electromagnetically.	smooth, dense, studio-like
Algorithmic Hall Reverb	Time	Digital algorithms recreate the reflections of a large room or hall without any physical medium.	spacious, cavernous
Shimmer Reverb	Time	A reverb tail is fed through an octave-up pitch shifter before decaying, layering a rising harmonic on top of the wash.	glowing, choral, ethereal
Multi-Tap Delay	Time	Several independent delay taps, each with its own time and level, sound together from a single input.	layered, rhythmic, complex
Ping-Pong Delay	Time	Successive repeats alternate between the left and right stereo channels.	bouncing, wide, spatial
Reverse Delay/Reverb	Time	The captured repeat or reverb tail is played back reversed rather than forward.	swelling, backwards, uncanny
Looper	Time	Records a phrase into memory and repeats it seamlessly, letting new parts be layered on top in real time.	layered, self-accompanying
Freeze/Sustain Pedal	Time	Captures a short slice of the incoming signal (often from a reverb tail) and holds it as an indefinite, static drone.	frozen, drone-like
Slapback Delay	Time	A single, short, quiet repeat with almost no feedback, historically produced with tape.	doubled, rockabilly, tight
Dotted-Eighth Delay	Time	Delay time is set to a dotted-eighth-note subdivision of the tempo, so repeats land between the beats rather than on them.	galloping, cascading, rhythmic

06 — Advanced Practice

Eighteen styles, five bullets each.

Ready-built practice templates, from Djent Chug to Feedback Sculpture, each tied to a Sonic Spectrum level. Pick one to drop its full checklist into your practice brief.

Djent Chug

Level 10

Lock palm-muted low-string 16ths to a click before adding any syncopation.
Keep the fretting hand's muting silent on string changes — no open buzz between chugs.
Practice the accent pattern alone on a single dead-note before applying it to a real riff.
Scoop the mid-range on the amp so the attack stays a click, not a growl.
Layer a second, doubled take slightly off-time to feel how tight the pocket needs to be.

Shoegaze Wash

Level 06

Set chorus and reverb first, then find chord voicings that still read through the blur.
Favor open-string drones under moving shapes so pitch centers stay anchored.
Use the tremolo/vibrato bar for slow, continuous pitch movement rather than dive-bombs.
Strum with a soft pick attack — the wash should smooth transients, not fight them.
Practice fading chords in with a volume pedal instead of picking them dry.

Blues Lead

Level 07

Spend more time on finger vibrato speed and width than on note choice.
Practice bending exactly to pitch against a sustained reference note.
Leave space — phrase in short calls with real silence between them, like a vocal line.
Work microtonal, unresolved bends deliberately, not just full-step target bends.
Keep the gain at driven-lead level, not distortion — the pick attack should still read.

Post-Rock Crescendo

Level 11

Start the riff clean and unaccompanied; only add gain and drums on the repeat.
Write the arrangement as a volume and density curve first, notes second.
Use delay repeats as a rhythmic layer, not just ambience, once the build begins.
Practice the transition point into full gain as its own exercise, not just 'the loud part'.
Let a single motif survive from the clean intro through the peak, so the build stays recognizable.

Math-Rock Angularity

Level 04

Isolate the odd-meter grouping (e.g. 2+2+3) and count it out loud before playing it.
Keep the tone clean-to-light-crunch so the interval leaps stay legible.
Practice hands separately: fretting-hand shape first, then add the picking pattern.
Alternate tapped and picked notes inside the same lick to compare articulation.
Loop a two-bar phrase at a slow tempo until the accents feel automatic, then raise tempo.

Jazz Comping

Level 02

Voice chords on the middle four strings first — low root-position shapes get muddy fast.
Practice comping rhythms against a metronome on beats 2 and 4 only, no downbeats.
Use fingerstyle or thumb-lead picking so the attack stays soft under a soloist.
Walk simple chord-tone bass lines between changes with the thumb while comping on top.
Leave silence on beat one sometimes — comping is a conversation, not a wall of chords.

Ambient Drone

Level 13

Start from a single sustained note or open-string dyad, not a chord progression.
Use an e-bow or volume swells so the attack transient disappears entirely.
Layer a looper part first, then improvise sparse melodic fragments on top.
Ride the reverb/delay mix live — the wash is an instrument you're playing, not a fixed setting.
Practice doing nothing for eight full bars; restraint is the technique here.

Thrash Rhythm

Level 09

Down-pick everything at first, even fast passages, before allowing any alternate picking in.
Keep the noise gate tight so palm-muted 16ths don't bleed into each other.
Practice the gallop rhythm (down-down-up feel) isolated on one open string before riffing.
Match kick-drum downbeats exactly — thrash rhythm guitar is a percussion part first.
Alternate between chugged low strings and open-string gallops to build hand stamina.

Doom Sludge

Level 11

Tune down and leave the low end in the mix rather than tightening it away.
Practice riffs at half the tempo you think they need — doom lives in the space between hits.
Let chords ring past the next hit sometimes; total silence between notes isn't the goal here.
Use fuzz over high-gain distortion for a thicker, less-defined low end on purpose.
Practice a single power chord held for a full 8 counts, focused only on decay and feedback.

Funk Skank

Level 03

Practice muted 16th-note strumming with the picking hand alone, no fretting-hand movement yet.
Accent the 'and' of beat two and four before adding any melodic movement.
Use an envelope filter or light wah to add movement without adding sustain.
Keep chord voicings small (two or three notes) so the rhythm stays sharp, not thick.
Practice locking to a bass line recording, not just a click — funk rhythm is a duet with bass.

Prog Odd-Meter Riffing

Level 09

Write the riff's rhythm on paper first (e.g. 7/8 as 2+2+3) before touching the guitar.
Practice the meter with simple downstrokes on one note before adding real pitches.
Loop the bar that changes meter in isolation until the switch feels natural.
Keep palm muting consistent through the meter change so the rhythm reads clearly.
Count out loud while playing until the odd grouping is internalized, not counted.

Fingerstyle Folk

Level 01

Anchor a steady alternating-thumb bass pattern before adding any melody on top.
Keep nails or fingertips consistent — tone changes a lot with contact point.
Practice the thumb and finger parts completely separately before combining them.
Use open tunings sparingly at first — standard tuning already offers plenty to work with.
Record yourself; fingerstyle timing errors are easy to feel but hard to hear live.

Surf Twang

Level 04

Lean on the bridge pickup and a bright, clean-to-edge-of-breakup amp setting.
Add spring reverb generously — the wet, splashy decay is the genre's signature.
Practice fast alternate-picked single-note lines on the wound strings for that 'twang'.
Use a light bar vibrato on held notes rather than finger vibrato.
Keep phrases short and repetitive; surf melodies are riffs, not extended solos.

Neoclassical Shred Lead

Level 08

Practice sweep-picked arpeggios slowly with a metronome, prioritizing clean string changes over speed.
Work diminished and harmonic-minor scale shapes as their own separate drill.
Alternate legato runs and picked runs on the same scale to compare articulation and speed ceiling.
Use a metronome subdivision click, not just a beat click, to catch uneven 16th-note runs.
Record and slow down playback to catch which notes in a fast run are actually landing clean.

Sludge / Noise Rock

Level 12

Deliberately let some strings ring dissonant against a bent note — clash is part of the palette.
Practice pick scrapes and muted scratches as transition devices between riffs.
Use a fuzz-into-drone approach: hold a chord until pitch blurs into pure texture.
Work dynamics in extremes — near silence to full noise, with little in between.
Practice feedback control at low stage volume first before trying it at performance volume.

City-Pop / Yacht Clean

Level 05

Practice chorus-laden clean chord voicings with extensions (9ths, maj7ths) rather than plain triads.
Keep the picking hand light — this style rewards a relaxed, even attack.
Work hybrid picking so chord tones and a moving bass note can sound together.
Add a short slapback or subtle stereo delay rather than a large ambient wash.
Practice comping behind a groove-locked bass and drum recording, not alone.

Black Metal Tremolo Wall

Level 11

Build tremolo-picking endurance with short, timed bursts before attempting full riffs.
Keep the fretting hand's shape simple (single notes or small intervals) so the picking hand can stay fast.
Practice at a reduced tempo with a metronome until the tremolo feels even, not just fast.
Let the wall-of-gain tone blur individual picks together instead of fighting for clarity.
Alternate tremolo bursts with sudden silence to practice dynamic control, not just speed.

Feedback Sculpture

Level 15

Practice at real performance volume in a safe, controlled room — this technique doesn't work quietly.
Map which distances and angles from the amp produce which pitches, note by note.
Use a sustain/freeze pedal to capture a feedback moment and study its harmonic content.
Practice starting and stopping feedback cleanly with hand muting, not just backing away.
Treat body movement as an instrument control, not stage performance — small shifts change pitch.

50 guitarists with era, approach, key technique, a practice entry point, tags, and fact-check status

Django Reinhardt	1930s-40s, European jazz	Gypsy jazz (jazz manouche) pioneer	Rebuilt his solo technique around only the index and middle fingers of his fretting hand after his ring and little fingers were left permanently curled by burn-scarring from a 1928 caravan fire.	Practice a simple single-line solo using only two fretting fingers to feel the constraint that shaped his style.	jazz, gypsy jazz, chord-melody	checked
Wes Montgomery	1950s-60s, jazz	Octave-based melodic soloing	Played exclusively with his picking-hand thumb rather than a pick — adopted to practice quietly at night, then kept for its warmer tone.	Play a simple melody with the thumb alone and compare the tone against a pick.	jazz, thumb-picking, octaves	checked
Charlie Christian	Late 1930s-40s, swing	Early amplified single-note soloing in a big-band context	Horn-like single-note phrasing carried by one of the first widely-heard amplified hollowbody guitars.	Transcribe a short single-note swing-era phrase and focus on even, horn-like phrasing.	swing, electric pioneer, single-note lines	general
B.B. King	1950s onward, blues	Blues singer-guitarist	Named every guitar he owned 'Lucille' after running back into a burning nightclub in Twist, Arkansas in 1949 to save his instrument.	Practice one sustained note using only vibrato and a bend, no other notes, until it 'sings.'	blues, vibrato, call-and-response	checked
Albert King	1960s-70s, blues	Left-handed blues guitarist	Played a right-handed guitar without reversing the string order, so his bends pulled downward with gravity's help for unusually wide, dramatic bends.	Try bending a string in the opposite direction from usual to feel how string order changes bend leverage.	blues, string bending, unconventional stringing	checked
Muddy Waters	1940s-50s, Chicago blues	Electrified Delta blues slide guitar for a full band	Slide guitar carried over a driving electric backbeat.	Practice open-tuning slide over a slow 12-bar blues.	blues, slide, chicago blues	general
Chuck Berry	1950s, rock and roll	Guitar-driven rock and roll songwriting	Double-stop-based riffs and intros that became a template for rock rhythm guitar.	Learn a simple double-stop riff on the two lowest strings.	rock and roll, double-stops, riffing	general
Jimi Hendrix	Late 1960s, psychedelic rock	Psychedelic rock innovator	Left-handed; played a right-handed Fender Stratocaster flipped upside-down and restrung for left-handed playing, then used his freed thumb to fret bass notes while his fingers held chords above.	Practice fretting a bass note with the thumb while the fingers hold a chord shape above it.	psychedelic rock, feedback, thumb-fretting	checked
Jimmy Page	Late 1960s-70s, hard rock	Riff-based hard rock after a career as a session guitarist	Layered, riff-centric arrangements; also known for drawing a violin bow across the strings on select recordings.	Try an e-bow (or a real bow, carefully) on a held note and compare it against a picked note.	hard rock, riffing, bowed guitar	general
Eric Clapton	1960s onward, blues rock	Blues-rock phrasing rooted in Chicago and Delta blues vocabulary	Sustained, vocal-style string bending and vibrato carried across a power-trio format.	Take one blues scale shape and phrase it as if singing a lyric line.	blues rock, bending, phrasing	general
Carlos Santana	Late 1960s onward, Latin rock	Latin rock fusing blues phrasing with Latin percussion grooves	Long, sustained, vocal-like note choices played over syncopated Latin rhythm sections.	Practice holding single notes for a full bar over a clave-based rhythm track.	latin rock, sustain, melodic phrasing	general
Ritchie Blackmore	1970s, hard rock	Riff-based hard rock with classical and neoclassical influence	Fast alternate-picked runs drawing on classical-minor scale patterns, ahead of the later neoclassical shred movement.	Play a harmonic-minor scale run at a slow tempo, focusing on even alternate picking.	hard rock, neoclassical, riffing	general
Tony Iommi	Late 1960s onward, heavy metal	Heavy metal pioneer	After a 1965 factory accident cut off the tips of his right-hand middle and ring fingers, he built homemade fingertip prosthetics from a melted plastic bottle and leather, then moved to lighter strings and down-tuning to make bending possible again.	Try fretting with reduced fingertip feel (e.g. thin gloves) to sense why lighter strings and lower tuning would help.	heavy metal, down-tuning, prosthetic technique	checked
Angus Young	1970s onward, hard rock	High-energy blues-rock riffing built for live performance	Economical, riff-first rhythm playing paired with concise, vocally-phrased solos.	Practice a simple blues-rock riff at performance energy, not just correct notes.	hard rock, riffing, blues-based	general
Eddie Van Halen	Late 1970s onward, hard rock	Virtuosic hard rock	Widely credited with popularizing two-hand tapping in mainstream rock; the underlying idea of tapping the fretboard predates him, used earlier by players including Harvey Mandel and Steve Hackett.	Practice a simple tapped triplet figure (tap-pull-hammer) slowly before adding a tremolo-bar dive.	tapping, hard rock, tremolo bar	checked
Randy Rhoads	Late 1970s-80s, hard rock/metal	Neoclassical-influenced metal lead guitar	Classically-informed phrasing and scale choices layered onto hard rock rhythm parts.	Practice a classical-minor arpeggio shape and apply it over a rock power-chord vamp.	neoclassical, metal, phrasing	general
Yngwie Malmsteen	1980s onward, neoclassical metal	Neoclassical shred drawing explicitly on Baroque violin vocabulary	Sweep-picked arpeggios and fast alternate-picked scalar runs at high tempo.	Practice a three-string sweep arpeggio slowly, prioritizing clean note separation over speed.	neoclassical, sweep picking, shred	general
Steve Vai	1980s onward, experimental rock	Experimental virtuoso rock across a wide technical and timbral range	Extensive whammy-bar control combined with unconventional scale choices and phrasing.	Practice a sustained note while slowly working the whammy bar through small, controlled pitch movements.	experimental, whammy bar, virtuoso	general
Joe Satriani	1980s onward, instrumental rock	Instrumental rock built on strong, singable melodic lines	Legato-heavy phrasing that keeps instrumental solos melodically memorable rather than purely technical display.	Write or learn a short wordless 'vocal' melody and play it as a lead line.	instrumental rock, legato, melody	general
Stevie Ray Vaughan	1980s, Texas blues revival	Aggressive, high-energy blues drawing on Texas blues and Hendrix's vocabulary	Heavy picking attack combined with wide, fast vibrato and a thick tone from heavy-gauge strings.	Practice a blues shuffle rhythm with a deliberately hard, committed picking attack.	texas blues, vibrato, attack	general
Slash	Late 1980s onward, hard rock	Melodic hard-rock lead guitar	Bluesy, singable phrasing built around a thick, saturated lead tone.	Learn a simple pentatonic phrase and focus on making it 'sing' rather than playing it fast.	hard rock, melodic lead, pentatonic	general
Kirk Hammett	1980s onward, thrash metal	Thrash metal lead guitar	Wah-driven lead lines layered over thrash rhythm sections.	Practice a pentatonic lead lick while sweeping a wah pedal through it.	thrash metal, wah, lead	general
James Hetfield	1980s onward, thrash metal	Thrash metal rhythm guitar	Precise, high-speed down-picking for a tight, aggressive rhythm sound.	Practice down-picked 8th-notes on a single muted string before adding real riffs.	thrash metal, down-picking, rhythm	general
Dimebag Darrell	1990s, groove metal	Groove metal riffing	Pinch harmonics combined with heavily syncopated, groove-driven riffing.	Practice landing a clean pinch harmonic on one palm-muted note before working it into a riff.	groove metal, pinch harmonics, riffing	general
John Petrucci	1990s onward, progressive metal	Progressive metal with high technical precision across odd meters	Alternate-picking accuracy applied to complex, shifting time signatures.	Practice a simple alternate-picked line in 7/8 with a metronome before adding speed.	progressive metal, alternate picking, odd meters	general
Alex Lifeson	1970s onward, progressive rock	Textural layering that fills the space a second guitarist would in a trio	Chorus- and delay-shaped chordal textures supporting a power-trio format.	Practice a simple chord progression with chorus and delay, listening for how the effects 'fill in' the arrangement.	progressive rock, textural layering, effects	general
Robert Fripp	1970s onward, art rock	Angular, disciplined art-rock guitar	Also pioneered a real-time tape-loop technique (nicknamed 'Frippertronics') built from two reel-to-reel decks to layer sustained, evolving textures.	Loop a short phrase (with a looper pedal or app) and improvise a second part over your own loop.	art rock, looping, precision picking	checked
David Gilmour	1970s onward, progressive/art rock	Melodic, sustain-driven lead guitar built for spacious arrangements	Long, sustained bends paired with a strong sense of when not to play.	Practice a single bent note held over several bars, focused purely on sustain and pitch accuracy.	melodic rock, sustain, bending	general
Brian May	1970s onward, rock	Orchestral rock guitar arranging	Multi-tracked, harmonized guitar lines arranged to sound like a small orchestral section.	Record a simple melody, then record a second harmony line a third above it.	harmonized guitar, arranging, layering	general
Mark Knopfler	Late 1970s onward, roots rock	Fingerstyle rock and roots-influenced lead guitar, largely without a pick	Thumb-and-fingers picking used for both rhythm and lead lines.	Practice a simple lead line fingerstyle instead of with a pick, and compare the attack.	fingerstyle, roots rock, dynamics	general
John Frusciante	1980s-90s onward, funk rock	Funk-rock rhythm playing paired with melodic, economical lead lines	Syncopated funk chord stabs alternating with sparse, vocal-style soloing.	Practice a muted 16th-note funk rhythm, then strip it back to just the accented hits.	funk rock, rhythm, economy	general
Tom Morello	1990s onward, experimental rock	Experimental rock guitar built around effects and unconventional playing devices	Pickup-toggle-switch stuttering and turntable-style scratching sounds produced entirely on guitar.	Rapidly flick the pickup selector switch while holding a sustained note to hear the stutter effect.	experimental, effects manipulation, rhythm	general
Jack White	2000s onward, garage rock	Raw, minimal garage-blues guitar	Heavily filtered, fuzz-and-slide tone built to sound deliberately unpolished.	Practice a simple blues riff through fuzz alone, with no other effects.	garage rock, fuzz, slide	general
Kevin Shields	Late 1980s onward, shoegaze	Shoegaze wall-of-sound guitar	Holds the tremolo (whammy) arm continuously while strumming — a technique often called 'glide guitar' — to blur chords into a smeared, wavering wash.	Hold the tremolo bar lightly while strumming a simple chord and listen to how it changes the chord's attack.	shoegaze, tremolo arm, wall of sound	checked
Johnny Marr	1980s, post-punk/indie	Jangly, texturally dense rhythm guitar	Layered, arpeggiated open-chord voicings that function almost like a second melodic instrument.	Practice arpeggiating an open-chord shape evenly instead of strumming it.	jangle pop, arpeggios, texture	general
Nile Rodgers	1970s onward, funk/disco	Funk and disco rhythm guitar, known as 'the chop'	Extremely tight, muted 16th-note strumming with sparse chord voicings.	Practice a muted funk strum pattern with a metronome, keeping the right hand moving even on silent strokes.	funk, disco, rhythm chop	general
Prince	1980s onward, funk rock	Genre-blending funk-rock guitar across a wide stylistic range	Combined tight funk rhythm playing with hard-rock lead bursts inside the same song.	Practice switching between a muted funk rhythm and a short, aggressive lead phrase within one 8-bar phrase.	funk rock, versatility, dynamics	general
Paco de Lucía	1970s onward, flamenco	Flamenco guitar, later flamenco-jazz fusion	Picado — a fast, precise alternate-finger single-note technique central to flamenco lead playing.	Practice alternating index and middle finger on a single string at a slow, even tempo.	flamenco, picado, fingerstyle	general
Al Di Meola	1970s onward, jazz fusion	High-speed jazz fusion picking	Extremely fast, precise alternate picking applied to complex fusion lines.	Practice a simple scale run with a metronome, raising tempo only once the previous speed is completely clean.	jazz fusion, alternate picking, speed	general
John McLaughlin	1970s onward, jazz fusion	Jazz fusion built on odd meters and Indian classical influence	Rapid legato and picked lines phrased across shifting, non-4/4 time signatures.	Practice a simple scalar phrase in 9/8, counting the subdivision out loud.	jazz fusion, odd meters, legato	general
Pat Metheny	1970s onward, jazz fusion	Melodic jazz fusion, later guitar-synthesizer exploration	Long, horn-like melodic phrasing, often extended with guitar-synthesizer textures.	Practice a melodic phrase thinking like a horn player phrasing a breath, not a guitarist fretting a lick.	jazz fusion, melody, guitar synthesizer	general
Derek Trucks	1990s onward, southern rock/blues	Slide guitar rooted in blues and southern rock, played without a pick	Fingerstyle slide guitar with unusually precise pitch control for the technique.	Practice landing a slide exactly on pitch over a single sustained note, checked against a tuner.	slide guitar, southern rock, fingerstyle	general
Duane Allman	Late 1960s-70s, southern rock	Southern rock slide guitar pioneer	Open-tuning slide guitar integrated into a twin-lead rock band format.	Practice a simple slide phrase in open E or open G tuning.	southern rock, slide, open tuning	general
Ry Cooder	1970s onward, roots/americana	Roots and Americana slide guitar and stylistic historian	Slide guitar drawing on blues, gospel and world-music vocabulary.	Practice a slow slide melody focused on vibrato and dynamics rather than speed.	roots music, slide, americana	general
Bill Frisell	1980s onward, ambient jazz/americana	Ambient-leaning jazz and Americana textural guitar	Volume-swelled, effects-shaped notes that blur the line between guitar and ambient pad.	Practice a simple melody using only volume-pedal swells, with no pick attack audible.	ambient jazz, americana, volume swells	general
Fred Frith	1970s onward, avant-garde	Experimental/avant-garde guitar, often played flat like a table	Prepared guitar — objects placed on or against the strings to produce non-standard timbres.	Place a small object (a coin, a clip) against a string and explore the sounds it makes when picked or bowed.	experimental, prepared guitar, avant-garde	general
Lee Ranaldo	1980s onward, noise rock	Noise-rock guitar built on alternate tunings	Custom, non-standard tunings chosen to open up new chord shapes and drones.	Retune one string away from standard and explore the new open intervals it creates against the others.	noise rock, alternate tuning, texture	general
Michael Hedges	1980s onward, solo acoustic	Percussive fingerstyle acoustic guitar	Combined two-handed tapping and slap harmonics with unconventional open tunings on steel-string acoustic.

08 — Duet Practice

50 roles for two guitars.

Practising with a second player changes what your part is for. Fifty concrete roles across five families — foundation, harmony, interplay, texture, contrast — each with an approach, what it gives the other player, and the dynamic to expect. Select one to synthesise into your practice brief.

50 duet roles with family, approach, complement and dynamic

Rhythm Anchor	Foundation	Hold a steady, unornamented strumming or picking pulse.	Frees the other player to move freely in time.	You are the floor; timing errors show up in you first.
Groove Locking Partner	Foundation	Match your rhythmic subdivision exactly to a bass or kick pattern.	Turns two independent parts into one felt groove.	Requires listening more than playing — the pocket comes first.
Bass-Register Support	Foundation	Play root notes or simple bass-register lines under the other guitar's chords.	Gives harmonically thin voicings a foundation without a bass player.	Stay out of the other part's register; low and simple beats low and busy.
Pedal-Point Holder	Foundation	Sustain or repeat one note under changing harmony above it.	Lets the other player's chords create tension against a fixed center.	Your stillness is what makes their movement audible.
Downbeat Definer	Foundation	Land clearly and only on beat one of each bar.	Gives a free-time or syncopated partner a clear reference point.	Minimal but essential — the duo can drift without this anchor.
Muted-Pulse Engine	Foundation	Keep a constant palm-muted 8th- or 16th-note pulse going underneath everything.	Turns any melodic idea above it into a groove instantly.	Stamina role — the pulse must not waver even as the other part gets busier.
Low-End Foundation	Foundation	Favor the guitar's lowest two or three strings almost exclusively.	Leaves the full mid-and-high register open for the other player.	Register discipline matters more than note choice here.
Metric Timekeeper	Foundation	Count and physically mark odd or shifting meters clearly through your part.	Gives a soloing partner the confidence to take rhythmic risks.	You carry the map; they can wander because you won't.
Ostinato Base	Foundation	Repeat a short fixed pattern without variation for extended stretches.	Creates a stable backdrop for development happening in the other part.	Resist the urge to vary it — repetition is the whole job.
Drone Anchor	Foundation	Sustain a single note or open interval for long durations, with minimal movement.	Gives a melodic partner a tonal center to resolve tension against.	Patience-heavy; your part can feel like it's doing very little and still be essential.
Harmony Third Above	Harmony	Shadow the lead melody a third higher, note for note.	Thickens a single-note line into a two-part harmony instantly.	Requires knowing the key well enough to pick the right third on the fly.
Harmony Third Below	Harmony	Shadow the lead melody a third lower, note for note.	Adds weight and warmth under a melody rather than brightness above it.	Easy to clash if the interval isn't tracked against the underlying chord.
Octave Doubler	Harmony	Play the exact same line as the other guitar, one octave away.	Widens a single line without adding any new harmonic information.	Timing has to be near-perfect or the doubling reads as sloppy rather than thick.
Extended-Chord Colorist	Harmony	Add 9ths, 11ths or 13ths on top of the other player's simpler triads.	Turns a plain chord progression into a richer harmonic bed.	Needs restraint — one colored chord can say more than four in a row.
Suspension Resolver	Harmony	Hold a note that clashes with the current chord, then resolve it a beat later.	Creates a small tension-and-release moment inside a static progression.	Timing the resolution is the entire effect — too early and it disappears.
Counter-Melody Weaver	Harmony	Play a second, independent melodic line that moves against the main one.	Adds interest without doubling or simply supporting the lead.	Needs to be distinct enough to hear as its own line, not a mistake in the melody.
Inner-Voice Filler	Harmony	Add the middle notes of chords the other guitar is only implying with a partial voicing.	Completes harmony that would otherwise rely on the listener's ear to fill in.	Stay low in the mix — this role supports, it doesn't announce itself.
Parallel Harmony Shadow	Harmony	Move in the same rhythmic and melodic direction as the lead at a fixed interval throughout.	Creates a thick, unified two-guitar 'single instrument' sound.	Works best when both players treat the two parts as one voice, not two.
Contrary-Motion Partner	Harmony	Move in the opposite direction to the lead line — up when it goes down, and back.	Creates harmonic interest and voice-leading clarity a parallel line can't.	Requires the most advance planning of any harmony role — it rarely works improvised.
Unison Reinforcer	Harmony	Play the exact same notes, same octave, as the other guitar.	Adds thickness and certainty to a riff without adding new harmony.	The simplest harmony role, but timing has to be identical to earn its keep.
Call-and-Response Partner	Interplay	Play a short phrase, then stay silent while the other player answers.	Turns a solo idea into a musical conversation.	Listening is the technique — your next phrase should react to their last one.
Question Asker	Interplay	End your phrases on an unresolved note or rhythm that invites an answer.	Sets up the other player with something specific to respond to.	An unresolved ending is a request, not a mistake — leave it open on purpose.
Answer Giver	Interplay	Resolve or comment directly on the phrase the other player just left open.	Closes the loop the question-asker opened.	React to what was actually played, not a pre-planned lick.
Trade-Off Soloist	Interplay	Alternate full phrases or bars with the other player, like trading fours in jazz.	Keeps a solo section varied without either player having to sustain it alone.	Requires agreeing on a length (2, 4, or 8 bars) before starting.
Interlocking Riff Partner	Interplay	Play a riff that only makes rhythmic sense combined with the other player's riff.	Two simple parts combine into one part too complex for either to play alone.	Neither part should sound complete by itself — that's the design, not a flaw.
Hocket Partner	Interplay	Split a single melodic line so each player plays only alternating notes.	Creates one continuous line out of two players trading single notes rapidly.	Extremely timing-sensitive; a missed note leaves an audible gap.
Echo Responder	Interplay	Repeat the other player's last phrase a beat or two later, quieter or more sparsely.	Simulates a natural echo or reverb using a second live player.	Simplify what you repeat — an exact copy reads as delay, a varied one reads as commentary.
Rhythmic Displacement Partner	Interplay	Play the same phrase as the other guitar but shifted to start on a different beat.	Creates rhythmic tension from otherwise identical material.	Both players need to know the 'true' downbeat so the shift stays intentional.
Unison-Break Partner	Interplay	Play in unison for a passage, then break apart into independent parts at a cued moment.	Marks structural transitions (verse to chorus, build to peak) with a clear before/after.	The moment of the break should feel decisive, not accidental.
Conversation Interrupter	Interplay	Deliberately cut off the other player's phrase early with a strong entrance.	Adds energy and unpredictability to an otherwise polite trade-off.	Use sparingly — it only reads as exciting if it's rare.
Textural Pad	Texture	Hold slow-moving, effects-heavy chords with no rhythmic definition.	Gives a rhythmically active partner a stable harmonic bed to sit on.	Resist adding rhythm of your own — stillness is the contribution.
Ambient Bed Layer	Texture	Use reverb, delay and volume swells to remove your own attack transients.	Fills the space around a dry, articulate lead without competing with it.	You should be felt more than consciously heard.
Space-Leaving Minimalist	Texture	Play far less than feels natural — single notes, long rests.	Creates room for a busier partner's part to actually be heard clearly.	The hardest role to commit to; the temptation to fill space is constant.
Feedback/Drone Colorist	Texture	Introduce controlled feedback or sustained drone tones at the edges of the arrangement.	Adds texture and tension without adding melodic or rhythmic information.	Needs a volume and gain setup that can sustain without becoming the whole mix.
Arpeggio Shimmer Layer	Texture	Pick fast, even arpeggios high on the neck under a slower lead melody.	Adds motion and brightness without competing melodically.	Keep dynamics low and even — this role should shimmer, not shout.
Percussive Accent Layer	Texture	Add muted scratches, dead notes or body percussion at structural points.	Reinforces the drummer (or stands in for one) without adding pitched material.	Precision matters more than volume — these hits mark time.
Volume-Swell Layer	Texture	Fade notes or chords in with a volume pedal so no attack is audible.	Adds harmonic depth that seems to arrive from nowhere.	Timing the swell to land under, not over, the other player's phrase is the skill.
Modulation Wash Partner	Texture	Apply heavy chorus, phaser or rotary modulation to slow-moving chords.	Adds width and movement behind a more static or rhythmic partner.	Works best when the modulation rate doesn't fight the song's actual tempo.
Noise-Texture Layer	Texture	Use fuzz, ring modulation or prepared-guitar sounds as pure texture, not notes.	Adds an abstract, non-pitched layer that a conventional part can't provide.	Treat pitch as optional here — timbre is the entire message.
Sub-Bass Weight Layer	Texture	Play very low, sustained notes (down-tuned or on an extended-range instrument) beneath everything else.	Adds physical weight the other guitar's register can't reach.	Less is more — one held low note often does more than a busy bass line.
Register Contrast Partner	Contrast	Deliberately play in the opposite register (high vs low) from the other guitar.	Maximizes separation so both parts stay audible without EQ tricks.	Register discipline is the whole job — resist drifting toward the middle.
Density Contrast Partner	Contrast	Play sparsely while the other guitar is busy, and vice versa.	Prevents both parts from competing for the listener's attention at once.	Requires actively listening for the other player's density, not just your own part.
Dynamic Contrast Partner	Contrast	Stay quiet and restrained while the other player is loud, and swap on cue.	Creates a push-and-pull energy across a section rather than a flat volume.	Needs a clear, pre-agreed cue for when the swap happens.
Timbral Contrast Partner	Contrast	Stay clean while the other guitar is distorted, or vice versa.	Separates the two parts by ear instantly, even in a dense mix.	Works especially well when register and rhythm are otherwise similar.
Rhythmic Contrast Partner	Contrast	Play straight rhythms against the other player's syncopation, or vice versa.	Adds rhythmic interest without either part becoming rhythmically confusing alone.	Both parts need to share a common downbeat or the contrast reads as a mistake.
Tension Holder	Contrast	Sustain a dissonant note or unresolved rhythm against the other player's resolution.	Keeps a section from settling too soon.	Know exactly when you're supposed to release it — held too long, tension reads as error.
Release Provider	Contrast	Resolve the harmony or rhythm the other player has been holding in tension.	Gives the audience the payoff the tension-holder has been withholding.	Your entrance is a single decisive moment, not a gradual fade-in.
Lead Voice	Contrast	Take primary responsibility for the melody or solo line.	Gives the other player a clear part to support rather than compete with.	Leading means playing with intention — hesitant lead lines are hard to support.
Support Voice	Contrast	Actively subordinate your part's volume, density and register to the lead.	Makes the lead voice sound more confident and more audible.	A good support part is judged by how invisible it is, not how impressive.
Silence Holder	Contrast	Deliberately stop playing for a full phrase or section.	Makes the other player's part the sole focus, resetting the listener's attention.	Requires trust — sitting out can feel like doing nothing while doing exactly the job.

09 — Drums + Bass + Sub-Bass

90 patterns, eight voices.

A guitar part doesn't exist alone. Ninety rhythm-section patterns across kick, snare, hi-hat, overall groove feel, bass, sub-bass, extra texture and polyrhythm, each with an approximate frequency range and a note on how the guitar typically responds. Select any that describe your rhythm section to build a frequency map in your practice brief.

90 drum, bass and sub-bass patterns with category, feel, frequency range and guitar interaction

Four-on-the-Floor Kick	Kick	Steady, driving, one hit per beat.	Roughly 50-100 Hz fundamental.	Locks with down-picked guitar downbeats.
Double-Kick Blast	Kick	Continuous, machine-gun energy.	Roughly 50-100 Hz, transient-heavy.	Pairs with tremolo-picked or chugged 16th-notes.
Syncopated Kick Pattern	Kick	Off-beat, groove-forward.	Roughly 50-100 Hz.	Guitar palm-mutes land on the off-beats to reinforce the syncopation.
Blast Beat Kick	Kick	Extreme-tempo, an undifferentiated wall of hits.	Roughly 50-100 Hz, blurred transients at speed.	Guitar tremolo picking matches the overall density rather than tracking individual hits.
Gated Kick (Short Decay)	Kick	Tight, clicky, modern.	Fundamental trimmed back; click emphasized around 3-5 kHz.	Matches tightly palm-muted, high-gain chugging.
Open Kick (Long Decay)	Kick	Boomy, vintage, roomy.	Extends down toward 40 Hz.	Works best with a sparser, less-muted guitar part so low end doesn't collide.
Kick-Snare Alternation	Kick	Familiar basic rock beat foundation.	Kick ~50-100 Hz vs. snare ~150-200 Hz, well separated.	Guitar rhythm can subdivide freely since kick and snare already define the pulse.
Triplet Kick Pattern	Kick	Galloping, uneven.	Roughly 50-100 Hz.	Pairs with the classic thrash 'gallop' picking pattern.
Bomb Blast (Kick+Snare Unison)	Kick	Explosive, unified single hit.	Combined low-and-mid content.	Guitar accents land exactly on the unison hits and stay silent otherwise.
Odd-Meter Kick Anchor	Kick	Marks beat one clearly inside a shifting meter.	Roughly 50-100 Hz.	Guitar can use the kick as its one reliable downbeat reference in a complex meter.
Skank Beat (Fast Kick/Snare Alternation)	Kick	Relentless, grindcore-adjacent.	Alternates low and mid content rapidly.	Guitar tremolo picking or chugging matches the alternation's overall speed, not each hit.
Backbeat Snare (2 and 4)	Snare	The classic rock pulse.	Body around 150-200 Hz, crack around 2-5 kHz.	Guitar chord stabs often land with the backbeat for shared emphasis.
Ghost-Note Snare	Snare	Quiet, in-between texture hits.	Mostly body frequencies, low volume.	Guitar can add matching ghost-muted notes for a unified groove texture.
Rimshot Snare	Snare	Sharp, cutting accent.	Strong upper-mid and high crack.	Pairs well with a pinch harmonic or accented chord stab landing at the same instant.
Cross-Stick Snare	Snare	Dry, clicky, understated.	Mostly high frequency, little body.	Complements a quiet or clean-toned verse guitar part.
Snare Roll (Buildup)	Snare	Rising tension into a section.	Dense and broadband.	Guitar often holds or swells through the roll rather than competing rhythmically.
Flam Snare	Snare	Fat, slightly smeared accent.	Body plus a doubled transient.	Matches a guitar unison hit played very slightly detuned or doubled.
Double-Time Snare	Snare	Urgent, driving; the backbeat effectively doubles.	Same range as a standard backbeat, at double the rate.	Guitar rhythm often simplifies here to avoid clutter against the busier snare.
Marching/Militant Snare Pattern	Snare	Regimented, precise.	Tight body, sharp crack.	Pairs with strict down-picked rhythm guitar for a unified, mechanical feel.
Off-Beat Snare (Skank-Style)	Snare	Skipping, upbeat-forward.	Standard backbeat range.	Guitar skank chords land on the same off-beats.
Snare Drag/Buzz	Snare	Blurred, textural attack.	Broadband with a softened transient.	Works well under a legato or slide-guitar phrase rather than a sharply picked one.
Polymetric Snare Accent	Snare	Accents cycle through a different-length pattern than the rest of the kit.	Standard backbeat range.	A guitar riff cycling in its own separate meter creates the same slow realignment against it.
Closed Hi-Hat 8ths	Hi-Hat	Tight, driving.	Body around 300-500 Hz, shimmer extending past 10 kHz.	Matches an even 8th-note palm-muted rhythm guitar part.
Closed Hi-Hat 16ths	Hi-Hat	Busy, energetic.	Same range, denser hits.	Pairs with fast alternate-picked or tremolo rhythm parts.
Open Hi-Hat Accents	Hi-Hat	Washy punctuation on off-beats.	Extended shimmer, longer decay.	Guitar can leave space on the same off-beat to let the wash speak.
Foot-Splash Hi-Hat	Hi-Hat	Soft, breathy punctuation.	Brief broadband splash.	Works as a transition marker between guitar sections.
Hi-Hat Bell/Tip Accents	Hi-Hat	Bright, cutting single accents.	Concentrated high shimmer.	Doubles well with a sharp pick-attack accent on guitar.
Half-Open Hi-Hat Sizzle	Hi-Hat	Sustained, trashy texture.	Broadband high-frequency noise.	Pairs with a fuzz or high-gain wash where extra top-end texture won't clutter the mix.
Hi-Hat Swells (Pedal Control)	Hi-Hat	Slow crescendo of shimmer.	Rising high-frequency energy.	Mirrors a guitar volume swell for a coordinated build.
Odd-Grouped Hi-Hat Pattern	Hi-Hat	Accents grouped in 3s or 5s against a straight pulse.	Standard shimmer range.	Guitar can mirror the grouping or hold straight time against it for polymetric tension.
Double-Time Hi-Hat	Hi-Hat	Frantic, energetic.	Dense shimmer.	Guitar often simplifies rhythmically to avoid competing for the same rhythmic space.
Hi-Hat as Clock	Hi-Hat	Neutral, purely functional timekeeping.	Even, unaccented shimmer.	Frees the guitar to be rhythmically adventurous since the hi-hat holds the base pulse.
Trashy/Loose Hi-Hat	Hi-Hat	Loose, deliberately sloppy, garage energy.	Broadband, undefined.	Suits a raw, minimally-processed guitar tone rather than a tight modern one.
Straight Feel	Groove	Subdivisions divide evenly, no swing.	N/A — a feel, not a frequency.	Matches even, straight alternate-picked rhythm guitar.
Swung Feel	Groove	Subdivisions lean long-short, triplet-based.	N/A — a feel, not a frequency.	Matches a shuffle or blues rhythm guitar pattern.
Half-Time Feel	Groove	The backbeat halves, widening the sense of space.	N/A — a feel, not a frequency.	Guitar can play busier patterns without feeling rushed, since perceived tempo drops.
Double-Time Feel	Groove	The backbeat doubles, raising perceived energy.	N/A — a feel, not a frequency.	Guitar often simplifies to avoid rhythmic clutter against the doubled pulse.
Linear Groove	Groove	Kick, snare and hi-hat never land together, creating a rolling, continuous feel.	N/A — a feel, not a frequency.	Guitar can lock to any single drum voice and still feel grooved.
Pocket Groove (Behind the Beat)	Groove	Hits land a hair after the metronome for a relaxed, heavy feel.	N/A — a feel, not a frequency.	Guitar picking attack should also sit slightly back, not rush to compensate.
Pushed Groove (Ahead of the Beat)	Groove	Hits land a hair before the metronome for urgency.	N/A — a feel, not a frequency.	Guitar attack should lean forward too, or the two parts feel disconnected.
Motorik Groove	Groove	A steady, mechanical, repetitive pulse.	N/A — a feel, not a frequency.	Guitar textures or melodies can float freely on top since the pulse never varies.
Breakbeat Groove	Groove	Syncopated, sample-derived rhythmic complexity.	N/A — a feel, not a frequency.	Guitar often takes a secondary, texture-first role rather than competing rhythmically.
Waltz/Triple-Meter Groove	Groove	A three-beat cycle rather than four.	N/A — a feel, not a frequency.	Guitar chord changes or riff accents typically land on beat one of each three-count.
Shuffle Groove	Groove	Heavily swung, blues-rooted triplet subdivision.	N/A — a feel, not a frequency.	Guitar phrasing should swing the same triplet feel, not play straight against it.
Polyrhythmic Groove	Groove	Two competing pulses (e.g. 3-against-4) felt simultaneously.	N/A — a feel, not a frequency.	Guitar can lock to either pulse, changing the perceived feel of the same drum part.
Root-Note Pedal	Bass	Simple, foundational, unmoving.	Typical fundamental roughly 40-100 Hz.	Leaves full harmonic movement to the guitar above it.
Walking Bass Line	Bass	Constant quarter-note motion connecting chord tones.	Roughly 40-200 Hz, moving.	Common in jazz duets where the guitar comps chords on top.
Octave Bass Jumps	Bass	Energetic, bouncing between registers.	Alternates a low fundamental and its octave, roughly double the frequency.	Pairs with syncopated funk or disco rhythm guitar.
Syncopated Funk Bass	Bass	Percussive, off-beat-accented.	Roughly 40-200 Hz with sharp transients.	Locks tightly with a muted 16th-note funk guitar chop.
Unison Riff Bass	Bass	Thick, unified, aggressive.	Same fundamental as the guitar's low strings, reinforced.	Guitar and bass play the exact same riff for maximum weight.
Melodic/Lead Bass	Bass	The bass takes the melodic foreground.	Extends above roughly 200 Hz into the guitar's low register.	Guitar drops back into a supporting or textural role.
Slap Bass	Bass	Percussive, thumb-and-pluck attack.	Strong transient click plus roughly 40-150 Hz of body.	Guitar often lays out or plays sparse chords to leave room for the rhythmic complexity.
Pick-Played Bass	Bass	Brighter, more aggressive attack than fingerstyle.	Emphasizes upper harmonics within the same fundamental range.	Cuts through a dense, high-gain guitar wall better than fingerstyle bass.
Fretless Bass Glide	Bass	Smooth, vocal, continuously variable pitch.	Roughly 40-200 Hz with constant micro-pitch movement.	Pairs well with slide or legato-heavy guitar phrasing.
Chordal Bass	Bass	The bass plays two- or three-note chords rather than single lines.	Extends the bass's normal range upward.	Works best when the guitar plays single-note lines rather than competing chords.
Bass Drop	Bass	A dramatic, structural low-end arrival.	Falls toward 40 Hz or below at the drop point.	Guitar typically thins out or stops right before the drop to maximize its impact.
Call-and-Response Bass	Bass	Bass phrases answer or interject between guitar phrases.	Standard bass range, placed rhythmically in the gaps.	Requires the guitar to leave deliberate space for the bass to answer into.
Sustained Sub Drone	SubBass	A felt, physical low hum.	Roughly 20-60 Hz, held.	Guitar stays well above this register to avoid masking it entirely.
Sub Pulse	SubBass	Physical thump on structural downbeats.	Roughly 20-60 Hz, short decay.	Guitar rhythm accents can align with the pulse for combined physical impact.
Sub Bass Glide/Portamento	SubBass	A slow pitch slide felt more than heard.	Sweeps within roughly 20-60 Hz.	Works as a transition device between guitar sections.
Sine-Based Sub Layer	SubBass	Pure, undistorted low weight with no harmonic texture.	Roughly 20-60 Hz, minimal harmonics.	Leaves the guitar's own low end uncluttered, since this layer carries almost no overtones to collide with.
Distorted Sub Layer	SubBass	Aggressive, textured low weight.	Roughly 20-60 Hz fundamental with added upper harmonics.	Needs careful EQ coordination so it doesn't fight a down-tuned guitar's low strings.
Sub Bass Stab	SubBass	Percussive low punctuation.	Roughly 20-60 Hz, very short decay.	Pairs with a palm-muted guitar accent landing at the same instant.
Sub-Bass Drop Cue	SubBass	A structural marker signaling a section change.	Sudden arrival around 20-40 Hz.	Guitar typically drops out entirely for a beat before the sub arrives, for contrast.
Sub Bass Swell	SubBass	A slow-building low-end crescendo.	Rising energy within roughly 20-60 Hz.	Mirrors a guitar volume or gain swell happening at the same time.
Sub-Octave Guitar Layer	SubBass	An octave-down pitch-shifted copy of the guitar's own low string adds sub weight directly.	Roughly half the guitar's fundamental, into the 40-80 Hz range.	The guitar itself is generating sub content here, so gain staging must be managed carefully to avoid mud.
Sub Bass Silence	SubBass	The physical low end is conspicuously removed for contrast.	Near-total absence below roughly 100 Hz.	Makes the guitar's own low strings suddenly read as 'the bottom' of the mix.
Modulated Sub	SubBass	A slow, undulating pulse under everything.	Roughly 20-60 Hz, amplitude-modulated.	Guitar textures on top can stay static, since the sub layer alone provides movement.
Cymbal Swells	Texture	Rising, washy crescendo.	Broadband, weighted toward high frequencies.	Mirrors a guitar volume swell into a section peak.
Gong/Crash Accents	Texture	Massive, sustained punctuation at structural points.	Broadband with a long decay.	Guitar typically holds a chord or stops entirely right after the hit to let it ring.
Found-Object Percussion	Texture	Unpredictable, textural, non-kit sounds.	Variable, often broadband.	Pairs well with prepared-guitar or experimental techniques for a shared non-standard palette.
Tom Fills (Melodic Toms)	Texture	Rolling, pitched punctuation between sections.	Roughly 100-300 Hz depending on tom size.	Guitar often holds a static chord through a tom fill so the fill reads clearly against it.
Brush-Played Kit	Texture	Soft, textural, low-volume.	Broadband but low amplitude.	Suits a clean or lightly-driven guitar tone rather than high gain.
Programmed Glitch Percussion	Texture	Stuttering, digitally fragmented.	Variable, often high and short.	Pairs with bit-crushed or heavily processed guitar textures for a shared aesthetic.
Field-Recording Texture Bed	Texture	Ambient, non-rhythmic environmental sound.	Broadband, low-level.	Sits underneath an ambient or drone-based guitar part without competing rhythmically.
Reversed Cymbal Swell	Texture	A crescendo that seems to arrive from nowhere, timed to land on a downbeat.	Broadband, rising.	Works as a lead-in device right before a guitar section change.
Shaker/Tambourine Layer	Texture	Light, constant high-frequency motion.	Concentrated above roughly 5 kHz.	Adds perceived energy under a guitar part without adding low or mid clutter.
Bowed Cymbal	Texture	A sustained, eerie, pitched drone from a bow drawn across a cymbal edge.	High, sustained, with audible pitch.	Pairs naturally with bowed or e-bow guitar textures for a matched sustained palette.
Processed Room Ambience	Texture	The natural room sound itself, heavily reverbed or manipulated, used as an instrument.	Broadband.	Works with reverb-heavy ambient guitar parts as a shared spatial layer.
3-Against-4 Polyrhythm	Poly	Two pulses, in 3 and in 4, coexist within the same bar length.	N/A — a rhythmic relationship, not a frequency.	Guitar can lock to either pulse, changing how the same riff is perceived.
5-Against-4 Polyrhythm	Poly	A wider, more disorienting cross-pulse.	N/A — a rhythmic relationship, not a frequency.	Best introduced slowly, with guitar accents marking only one of the two pulses at first.
Polymetric Layering	Poly	Parts keep different bar lengths and drift in and out of phase, realigning only after a longer cycle.	N/A — a rhythmic relationship, not a frequency.	Classic pairing: a steady 4/4 kit under an odd-length guitar riff.
Metric Modulation	Poly	The perceived pulse changes while the underlying tempo stays constant.	N/A — a rhythmic relationship, not a frequency.	Guitar rhythm often triggers the modulation by regrouping its own subdivisions.
Additive Meter Groove	Poly	Uneven, lurching groupings (2+2+3, 3+3+2) rather than a smooth cycle.	N/A — a rhythmic relationship, not a frequency.	Guitar accents typically mark the start of each additive group so the grouping stays audible.
Nested Tuplets	Poly	Triplets inside a straight pulse, or the reverse, as a brief local effect.	N/A — a rhythmic relationship, not a frequency.	Works well as a single-bar guitar fill against an otherwise straight drum pulse.
Cross-Rhythmic Fill	Poly	A fill in a different meter than the surrounding groove, resolving back into the main pulse.	N/A — a rhythmic relationship, not a frequency.	Guitar typically holds steady through the fill so the drums' disruption reads clearly.
Layered Ostinati	Poly	Two or more repeating patterns of different lengths, slowly phasing against each other.	N/A — a rhythmic relationship, not a frequency.	Guitar can add a third, independent-length ostinato for a three-layer polymetric texture.
Hemiola	Poly	A temporary 3-feel inside a 2-feel bar, or the reverse.	N/A — a rhythmic relationship, not a frequency.	Guitar accents can either reinforce the hemiola or hold the original meter for tension.
Polyrhythmic Hi-Hat/Kick Split	Poly	Hands and feet independently keep two different cross-pulses.	N/A — a rhythmic relationship, not a frequency.	Guitar typically locks to just one limb's pulse rather than tracking both at once.
Displaced Downbeat Groove	Poly	The strongest-feeling hit is deliberately not on beat one.	N/A — a rhythmic relationship, not a frequency.	Guitar riffs written to start on the 'true' beat one create audible friction against the displaced accent.

10 — Genre Classifier

100 genres, scored live.

Seventy-eight real, documented genres plus twenty-two openly invented ones — each clearly marked “coined” wherever it appears, never presented as real. As you select techniques, effects and a spectrum level above, this list re-scores itself live against your choices.

11 — Common Questions

Asked before rehearsal.

Is the practice brief written fresh each time, or fixed content?

It's fixed content, recombined. Every technique, effect, player, role and pattern on this page is reference material written for the dashboard ahead of time. Selecting items composes them into a practice brief using a fixed set of if/then rules defined in this page's own code — every sentence the brief shows you traces back to a specific row or card above it.

What is a “practice brief”?

A short, structured reference sheet — setup, techniques, effects, tone target, session plan — assembled from whatever you've selected on this page, meant to be printed or read on a phone in a rehearsal room. It replaces flipping between ten browser tabs mid-rehearsal.

Are the genres on this page all real?

78 of the 100 genres listed are real, documented genres. The other 22 are openly invented mashups built for this dashboard, and every one of them carries a visible “coined” label wherever it appears in a table, list or the practice brief — never presented as a real genre.

Were the guitarist facts on this page checked?

The specific, checkable claims — Django Reinhardt's fretting-hand injury, Wes Montgomery's thumb technique, Tony Iommi's prosthetic fingertips, Albert King's reversed-strung guitar, Jimi Hendrix's restrung Stratocaster, Eddie Van Halen's tapping, B.B. King's “Lucille”, Robert Fripp's tape looping, Kevin Shields' tremolo-arm technique, and Michael Hedges' percussive harmonics — were independently checked against named sources before publishing (marked “checked” in Section 07's table). The remaining entries use general, well-established era/genre/technique characterisation rather than unverified specifics; see Sources below.

How was the colour-coding replaced?

Every category badge on this page uses a distinct symbol, a distinct border style (solid, dashed, dotted or double) for its broader family, and — wherever the source data includes an intensity or register value — a matching border weight and fill. The Sonic Spectrum uses a plain lightness ramp instead, since its 15 levels are ordered, not categorical. None of it depends on hue, so it reads the same in greyscale, print, or to a colour-blind eye.

Does anything here get sent anywhere?

No. Selections, the practice brief and the genre scores are all computed in your browser from the data on this page. Nothing is uploaded, logged or sent to a server by this tool.

Where the checked facts come from

This page states a great deal as reference (technique names, effect mechanisms, practice methodology) that doesn't need a citation because it isn't a factual claim about a real person or event. The specific, checkable claims — mostly in Section 07 and the frequency figures in Section 09 — are sourced below. Anything this pass could not verify to its own standard was softened or left out rather than asserted; see the note under Section 07's table.
