A blast beat is not one pattern — it’s a family of them.
Say “blast beat” and most people picture one thing: a blur of snare and kick at an impossible tempo. In practice it’s a small family of related patterns — traditional, hammer, bomb and gravity blasts — each trading off speed, stamina and control differently. This page works through what actually happens on the kit in each variant, where the technique came from, and how it connects to the groove-versus-grid material on programming feel.
01 — The Core Move: Kick and Snare, Alternating at Speed
The Core Move: Kick and Snare, Alternating at Speed
Strip a blast beat down to its simplest form and it’s a single-stroke roll split between two limbs: the kick and the snare alternate, one hit each, as fast and evenly as the drummer can manage, while the ride or hi-hat hand plays in unison with one of them — usually the kick. Lead with the kick and the pattern feels driving and forward; some drummers instead lead with the snare, which shifts where the accent naturally falls. Either way, the defining feature isn’t raw speed — a fast single-stroke roll on the snare alone isn’t a blast beat — it’s specifically this alternating kick-and-snare relationship.
Tempo is usually measured in 32nd notes at a minimum of roughly 90 beats per minute, which is the same physical rate as 16th notes at around 180 BPM — the threshold most drummers and writers treat as where a pattern starts counting as a blast beat rather than just a fast groove. Modern extreme-metal blast tempos regularly run from there up past 250 BPM.
02 — Hammer, Bomb and Gravity: Three Ways to Buy More Speed
Hammer, Bomb and Gravity: Three Ways to Buy More Speed
Once a drummer needs more speed or stamina than the traditional pattern allows, three related variants take over, each trading something different for it:
- Hammer blast — kick and snare hit together as straight eighth notes rather than alternating. Only one hand needs to move fast, which makes it a common entry point when a drummer’s weaker hand can’t yet hold tempo alone.
- Bomb blast — the snare plays straight eighth notes over a kick line running sixteenth notes underneath; the combination is sometimes nicknamed the “Cannibal” blast after its popularity among early-1990s death metal bands.
- Gravity (freehand) blast — a rebound technique using the snare rim as a fulcrum, letting one arm motion produce two snare hits. It roughly doubles the output of a conventional stroke, at the cost of volume and control, and is usually the last variant a drummer learns.
Which variant a drummer reaches for is mostly about which resource is scarce in the moment — a weaker hand, a demand for extra speed, or the need to sustain a pattern for longer than the traditional roll comfortably allows.
03 — Where It Came From
Where It Came From
Blast beats trace to the UK hardcore punk and grindcore scene of the mid-1980s, not to metal proper — hardcore punk’s own lineage, as a genre defined by speed, intensity and DIY ethics, is exactly the soil this technique grew out of before metal picked it up. The record most often cited as putting the pattern on tape is Napalm Death’s 1987 album Scum, with drummer Mick Harris commonly credited for developing it into a compositional building block rather than an occasional flourish.
That credit is worth holding loosely. As with most drumming techniques, related extreme-tempo patterns were being worked out in parallel by other players in overlapping scenes at close to the same time, and no clean single-inventor claim survives real scrutiny — the honest version of the story is a scene developing an idea together, with one record making it famous.
04 — Programming One That Doesn’t Sound Like a Machine
Programming One That Doesn’t Sound Like a Machine
Everything this site’s drum-programming page says about quantize versus humanize and ghost notes applies here, just at a more extreme tempo. A blast beat programmed at perfectly even velocity and perfectly even timing reads as mechanical almost immediately — small, deliberate variance between the kick and snare hits, and a touch of timing looseness rather than grid-perfect placement, is what keeps a fast pattern sounding like a person playing it rather than a drum machine imitating one.
It’s also worth practicing and monitoring this at a sane volume. Drummers sit closer to cymbals than almost any other instrumentalist, and NIOSH’s own guidance for musicians notes that band rehearsals commonly run above 91 dBA — well past the 85 dBA over eight hours the agency treats as a hazard threshold, with a 100 dBA passage capable of causing damage in as little as fifteen minutes. None of that is a reason to avoid the technique; it’s a reason to take the same care with rehearsal volume that this site’s gear pages take with gain staging.
05 — Common questions
Common questions
What’s the difference between a blast beat and just playing fast?
Speed alone isn’t the definition. A blast beat specifically alternates or combines kick and snare in one of the patterns above; a drummer playing a fast single-stroke roll on just the snare, with no kick involved, is playing fast — not blasting.
Which variant should a beginner learn first?
Traditional first, since it establishes the core alternating feel at a manageable tempo. Hammer blast is a reasonable second step because it only demands speed from one hand. Gravity/freehand blast is usually left for later — it needs a specific rebound technique that takes real time to control.
Did Napalm Death invent the blast beat?
They’re the band most commonly credited, largely because Scum (1987) is the record that put the technique on tape and made it visible. But similar extreme-tempo patterns were developing in parallel scenes at close to the same time, so treat “Napalm Death popularized it” as the accurate claim rather than “Napalm Death invented it.”
Does a blast beat always sound like a wall of noise in a mix?
No — that’s a production choice, not an inevitability. The gain-staging and kit-voicing decisions covered on this site’s tone-for-heavy-music page apply just as much to a blasting kit as to anything else; a well-produced blast beat can sit with real definition rather than collapsing into static.

Velocity, and what a blast is measured against
Slayer — The Velocity Engine
Priest's twin-guitar architecture accelerated past the point where tonality survives — harmony thrown out, the tritone kept, and the production stripped of everything that would soften it.
Atonality, in their own words
- Kerry King's actual thesis: "If it's not in key, it doesn't matter as long as it sounds cool." He describes his own leads as "archaic" and "demented." That's the whole philosophy in one sentence, and it's from him rather than a critic — though the word "atonal" itself is the critics'.
- Jeff Hanneman's version: "We weren't schooled musicians, but we knew what sounded dark. If it sounds like I'm standing over a body that's just been stabbed to death, then it's perfect." Dark by ear, not by theory.
- A surprise worth knowing: King is cautious about the whammy bar. "Stay away from the whammy until you're out of ideas, because it is way too easy to rely on it" — he recommends it as an accent only. The popular image of Slayer solos as pure dive-bomb noise is a bit unfair to the intent.
- Diabolus in Musica (1998) does reference the tritone — the medieval prohibition, "the devil in music." It's also documented as the band's first album played mostly in C♯. Flag: there is no documented acknowledgement by Slayer of the Black Sabbath tritone connection. That link is observational — which doesn't make it less useful for merging, just unsourced as intent.
The writing split, which matters more than you'd think
- Hanneman wrote almost everything canonical. "Angel of Death" (music and lyrics), the "South of Heaven" and "Seasons in the Abyss" title tracks (his music, Araya's lyrics), "War Ensemble," "Dead Skin Mask," "Blood Red," and "Raining Blood" co-written with King. If you're modelling Slayer, you're mostly modelling Hanneman.
- And Hanneman is the punk one. Lombardo: "Jeff Hanneman introduced me to punk. He was a big Suicidal fan." That hardcore DNA — not thrash, hardcore — is why the riffs are short, blunt and repetitive rather than progressive.
- The debut wore its influences on the sleeve: Show No Mercy (1983) credits Venom, Judas Priest, Iron Maiden and Mercyful Fate as major influences. And per King the band bonded on Priest covers before writing anything.
Dave Lombardo
- He used a single kick drum on Show No Mercy. He'd added a second before the sessions but hit technical trouble. Gene Hoglan helped him build the double-kick technique, and within roughly six months he went from "my left foot just wants to lag behind" to executing "Haunting the Chapel," described as the most brutal double bass written to that point.
- He credits jazz drummers with inventing the blast beat: "I heard it was jazz drummers, which I believe they probably did, because they did everything first before anybody." His structural definition of the blast: "double bass going and the snare hitting at the same 32nd notes."
- Tempo drift was an accident that became the sound: "[the songs] were slower" when written, "when we recorded them they just got faster and faster." And on Reign in Blood the band's instruction to him was simply "speed it up."
Araya, and the Rubin production
- Tom Araya on his own bass playing: "I really don't think of myself as a bassist extraordinaire. That's not me." And he's candid about the physical problem of singing and playing at once: "I have to cheat, because playing and singing at the same time is not easy" — on "Raining Blood" live, "there are parts where I just play an open E instead of the riff you hear on the record." That open-E substitution is a genuinely useful arrangement idea, not a failure.
- His early Show No Mercy shrieks are far higher than his later mid-range bark. Flag: a Halford influence on that early style is undocumented despite being the obvious guess — and Araya has said he wasn't a metal listener before joining: "The only time I recently started listening to metal music was when I joined the band." He later called Sabbath "the godfathers."
- Rick Rubin's Reign in Blood method, in his own words: "I was more subtractive than additive. It was getting back to the essence." And the instruction to engineer Andy Wallace that defines the record: "I didn't want it to be a blur of bass; I wanted it to be a pulse." He told the band they "didn't need any reverb on the guitars or vocals," producing "a sound that was as dry as a bone and heavy as granite."
- 28 minutes 58 seconds, trimmed from an initial ~34. Brevity was intentional. Columbia refused to release it — president Walter Yetnikoff objected to the cover and to "Angel of Death"; Hanneman's defence was that it was "like a history lesson." Rubin moved it to Geffen.
- Tone, and this will surprise you: King's EQ is an upside-down V — boosting mids, not scooping them, the exact inverse of Dimebag's approach. And the early records used "a little bit less gain than you might have initially thought" — a full-bodied crunch rather than all-out saturation. Three Marshall heads into six Mode Four cabs, which he likes because "more wood in them" makes it "feel heavier, that feels tuned lower, and is just fuller."
- Tempo: "Angel of Death" is documented at 210 BPM. Per-album ranges aren't systematically sourced. Pre-1998 tunings aren't documented either — E standard early is the reasonable assumption but it's inference.
2. THE SWUNG BLAST
Slayer ▸ Black Sabbath — A thrash record that shuffles.
The variable that moves: Swing moves forward in time — Bill Ward's feel at 200 BPM. The most radical merge in all three guides.
Hinge (what already agrees): Both bands' drummers came out of jazz, and both said so. Ward: "I'm playing jazz throughout the song 'Black Sabbath.'" Lombardo credits jazz drummers with inventing the blast beat — "they did everything first before anybody." The lineage is shared even though the results couldn't sound less alike.
Friction (what fights): This is the sharpest conflict of the six. Ward: "You can't play a backbeat in Black Sabbath — it's going to ruin the song," and he admits "I lacked the ability to play as a timekeeper." Slayer at 210 BPM is nothing but timekeeping — relentless straight thirty-second subdivisions where any looseness reads as a mistake.
Resolution: Don't swing the kick — swing the hands. Keep the double bass mechanically straight and locked so the song still functions as thrash, then put a triplet/shuffle feel in the ride and snare on top of it, and let the snare sit a hair behind. You get a thrash beat with a limp, which is a sound essentially nobody has made. Then restore two more Sabbath variables: a bass playing melodic counterpoint instead of doubling the riff, and space — a few bars where everything stops.
Recipe
- Chassis: Slayer — 190–210 BPM, ~3:00, tritone-saturated chromatic riffs, hard stop, no fade
- Drums — the whole point: straight locked double bass underneath, swung triplet ride-and-snare feel on top, snare deliberately a hair behind the beat. Jazz fills in the gaps rather than metal fills
- Guitar tone: Slayer's mid-boosted crunch with less gain than you'd expect, bone dry, no reverb
- Bass: Geezer's method imported wholesale — fingerstyle, high on the neck, biting, running counterpoint rather than following. This is the second-biggest change and it's what stops the arrangement being one-dimensional
- Space: two or three bars of near-silence mid-song — a single drone and a ride cymbal. Slayer almost never does this and it makes the return twice as heavy
- Vocals: Araya's machine-gunned barely-pitched bark, but phrased to the swing rather than against it
- Solo: atonal chaos, dive bombs as accents only (King's own advice)
- Mix: Rubin's subtractive rule — "I didn't want it to be a blur of bass; I wanted it to be a pulse." No reverb on guitars or vocals
- Avoid: swinging the kick drum. Do that and the song collapses into sludge. The kick is the grid; the swing lives above it.
6. THE HARMONISED BLAST
Slayer ▸ Judas Priest — The one thing Slayer took from Priest and then deliberately discarded.
The variable that moves: Harmony moves forward in time — Slayer kept Priest's two guitars and threw out the harmony. Put it back.
Hinge (what already agrees): Slayer are a twin-guitar band. They inherited the format directly from Priest — King says the two-guitar interplay on "Breaking the Law" is what shaped them. But they kept only the format and dropped the function: two guitars that trade chaos rather than harmonise melody. The apparatus is already installed and switched off.
Friction (what fights): Harmonised thirds require a key centre to be thirds of. Slayer's whole harmonic doctrine is King's "if it's not in key, it doesn't matter as long as it sounds cool." Harmonise an atonal riff and you get either accidental consonance — which sounds wrong for the band — or a stack of dissonance so thick it reads as noise.
Resolution: Harmonise the tritone itself rather than a melody. Move both guitars in strict parallel at the tritone or the minor second instead of the third, so the harmony is real, deliberate, locked and utterly sour — the discipline of Priest applied to the interval Slayer actually uses. Then reserve conventional harmonised thirds for one place only: a slow clean-ish middle section, where their sudden consonance is genuinely shocking. Priest's discipline, Slayer's material.
Recipe
- Chassis: Slayer — 180–200 BPM, ~3:30, bone dry, no reverb, mid-boosted crunch with less gain than expected, hard stop
- The core device: two guitars moving in strict locked parallel at the tritone or minor second — real harmony, disciplined and precise, and completely sour
- The reversal: one slow mid-song section where the guitars finally harmonise in conventional thirds. It should sound almost unbearably pretty in context. That's the event
- Drums: Lombardo's blast mechanics — "double bass going and the snare hitting at the same 32nd notes" — live, no triggers, plus ride-bell accents and hard cut-offs
- Bass: Rubin's rule — "a pulse, not a blur." Thin and articulate. Use Araya's live trick deliberately: drop to a single open low note under the fastest riffs so the guitars stay legible
- Vocals: Araya's machine-gunned barely-pitched bark for the body, with Halford-style layered self-harmonised backing vocals under the slow section — the only melodic voice in the song
- Solos: one atonal chromatic burst, then immediately a harmonised twin-lead line. The two philosophies back to back with no transition
- Mix: Rubin's subtractive approach throughout — nothing added, no reverb, no bass bloom
- Avoid: harmonising in thirds anywhere except that one section. Its scarcity is what gives it force.
