Growled or shrieked. Unintelligible without a lyric sheet. The thing most newcomers bounce off.

In short

Death metal with jazz harmony, tapping and impossible drumming. The more notes per second, the better.

How it sounds

  • Jazz harmony, extended chords and frequent modulation.
  • Fretless or slap bass treated as a lead instrument.
  • Polyrhythmic drumming and varied blast beats at the edge of what is physically possible.

Hear what that means

  • Jazz harmony, arriving

    Atheist - Unquestionable Presence

    Fretless bass, shifting metres and altered scales, played by musicians who were jazz players first. The harmony sounds unfamiliar rather than merely fast.

  • The bass as a lead

    Cynic - Focus

    Fretless bass and vocoded clean vocals on a death metal record in 1993. This is the point where the genre stops being death metal with more notes.

  • Where it became a competition

    Necrophagist - Epitaph

    Sweep-picked arpeggios at a tempo that made this record a benchmark for a decade. It is also where the genre's failure mode - difficulty as the whole content - becomes visible.

The specifics

Tempo
160-260 bpm
Song length
4-7 min
Tuning
Six, seven or eight strings in low tunings, and frequently fretless bass alongside. Jazz harmony arrives with the technique: diminished, whole-tone and altered scales rather than chromatic runs.
Production
Clean, precise and heavily edited, with every instrument separated. The production job is to keep four musicians playing different things simultaneously legible, which is the opposite problem from old school death metal's.
Written about
Consciousness and the cosmos, Mortality, abstractly, Mathematics, Science fiction

What each part is doing

  • Guitar Sweep-picked arpeggios and rapid legato over riffs that change key and metre inside a phrase. The scales come from jazz rather than from metal, which is what makes the harmony sound unfamiliar rather than merely fast.
  • Bass A lead instrument, frequently fretless and often the most technically accomplished part on the record. This is the only extreme genre where a bass solo is expected.
  • Drums Polyrhythmic and constantly shifting, with blast beats used as one texture among several rather than as the default state.
  • Vocals Growled, and deliberately kept simple — the vocal is the one element not competing for attention, because everything else already is.

What it isn't

That the technicality is showing off. On the founding records it is doing structural work: Atheist and Cynic were jazz musicians playing death metal, and the shifting metres and altered harmony are how those players think, not decoration bolted onto metal riffs. The genre did later accumulate records where difficulty is the entire content, which is a real failure mode — but blaming the founders for their imitators gets the history backwards.

Told apart from

  • Old school death metal The same instrumentation aimed at the opposite goal. Old school death metal wants weight and atmosphere; this wants precision and harmonic movement.
  • Progressive metal Progressive metal has the same virtuosity with clean singing, dynamics and an interest in songs. Technical death metal keeps the growl and the intensity throughout.
  • Brutal death metal Brutal death metal is as fast and far less harmonically restless — it is percussive where this is harmonic.
  • Djent Both are rhythmically complex and both use extended-range guitars. Djent works one rhythmic idea on the lowest string; this changes key, metre and texture continuously.

The genres this one is most often mistaken for. Written, not derived.

History

Chuck Schuldiner turned Death, album by album, from a brutal band into a nearly progressive one; Human and Individual Thought Patterns are the turning points. Atheist and Cynic brought jazz fusion directly into death metal. Necrophagist relaunched the genre in the 2000s with almost inhuman precision.
