Death metal — The Field Engine
A riff is a continuous field with a shape. Tremolo picking arrives fast enough that individual attacks stop being events and start being texture — so what you hear is a contour, not a sequence.
The buzzsaw, which is the most concrete fact in extreme metal
- A Boss HM-2 with all four knobs fully clockwise, into a solid-state combo, at Sunlight Studio in Stockholm. Tomas Skogsberg confirms it directly: “90 percent of the time, that Boss HM-2 pedal is the sound I work with primarily.” The amp on the early Nihilist and Entombed material was a Peavey Studio Pro 40.
- And it is mid-forward, not mid-scooped — which is the opposite of what everyone assumes. The pedal has a two-band tone stack: the Low control centres around 80–90 Hz, which Boss's own teardown notes aligns with a standard-tuned low E fundamental, and the High control sits at roughly 900 Hz to 1.3 kHz — upper midrange, not treble. Cranking both boosts bass and mids together. Skogsberg's nickname is Doctor Mid-range.
- The originator is named and it is not Skogsberg. Two independent sources — Guitar World and Daniel Ekeroth's Swedish Death Metal — credit Nihilist's Leif “Leffe” Cuzner, cranking all four knobs on the 1988 Only Shreds Remain demo. A bandmate: “You have the midrange on full. He bought the pedal and just cranked it.” Skogsberg himself declines the credit and calls it team-work.
- The tuning is genuinely contested. Guitar World says B standard with .010–.046; Skogsberg says C♯ or C; Ekeroth's book says C standard or lower. They agree only that it went down over time. Do not cite one pitch as the Swedish tuning.
The riff, and why “atonal” is the wrong word
- Tremolo picking is the primary articulation, where thrash's is palm-muted downpicking. The mechanical motion is identical to alternate picking; what differs is the left hand. Tremolo applies it to a static or very narrow pitch target as a repetition device; alternate picking applies it to a moving line as a traversal device.
- Calling it atonal is imprecise. Most riffs still orbit a pitch centre, usually the open low string acting as a drone or pedal, which is not atonality in any strict sense. “Chromatic and non-functional” is the accurate phrase — no functional harmony, no cadential resolution, but a tonal centre all the same.
- What is documented at transcription level: chromatically ascending power-chord shapes, artificial harmonic squeals, and — in one Morbid Angel analysis — a chorus that creates “the impression of a key-change without moving the song's tonal center”, achieved by register and voicing rather than by harmony.
- Tuning is measured. An empirical study of 287 guitar recordings found death metal bands using tunings three to five semitones below standard, most of them around C or B. That is the closest thing to a hard number the genre has.
The voice, from the laryngology rather than the forum
- “It's the false vocal folds” is directionally right and too simple. Imaging work at the University of Utah — laryngoscopy, EMG and dynamic MRI on working vocalists — finds multiple supraglottic structures vibrating above the true folds: epiglottis, aryepiglottic folds, ventricular folds, upper throat, tongue. In one subject the true folds were not even visible on camera.
- One finding is genuinely strange: the singer studied physically twists his larynx laterally during extreme screams, a movement not seen in conventional singing.
- “Growling damages your voice” is false as a blanket claim. The Utah imaging found no signs of damage even after career-length use, and the Complete Vocal Institute's laryngostroboscopic work concludes “screams can be done safely.” A 2007 report of vocal fold oedema and polyps exists but is attributed to improper technique. Injury tracks technique quality, as with any vocal misuse.
- And nobody invented the death growl. Precursors run through Lemmy, Cronos and Tom G. Warrior; Kam Lee describes developing his independently; the origins are near-simultaneous in 1983–84. Likewise “Possessed named the genre” overstates it — the term was already circulating in print by 1983 and Hellhammer used it the same year.
The drums, the triggers, and the Gothenburg branch
- Triggering is not a modern shortcut — it is as old as the genre. Scott Burns pioneered it at Morrisound in Tampa in the late 1980s using Cakewalk, MIDI and noise gates; for Terrorizer's World Downfall he sampled the kick through a TC 2290 delay and triggered it live across four tracks with no safety net. Entombed's 1990 debut used ddrum pads at Sunlight. Both founding studios got there independently at the same moment.
- The honest distinction is reinforcement versus replacement. Reinforcement layers a sample under the real hit, triggered off the real transient — the drummer's timing and dynamics survive and only part of the timbre is sampled. Replacement discards the mic'd sound. Blanket “fake drums” accusations conflate the two.
- Burns preferred solid-state amps — “heavier and more brutal” — Marshall Valvestate and Mesa heads, which is the same instinct as the Swedish Peavey combo from a completely separate scene.
- Melodic death metal is a specific graft, not death metal slowed down. The Gothenburg move is harmonised twin-guitar leads in a minor key — the NWOBHM tradition, functional and melodic — laid over death metal's non-functional tremolo riffing underneath. Two harmonic systems stacked, not blended.
