808 Patterns on the Kit

Trap 808 sub-bass kicks on an acoustic kit

Duration: 25 min Focus: Genre Vocabulary
Prerequisites

The 808 — Roland's TR-808 drum machine, born in 1980 and almost immediately rejected for being unconvincing — has become the defining bass voice of trap, drill, modern hip-hop and large parts of pop. The 808 kick is not a kick; it is a sub-bass note with a transient at the front. It can be tuned to a pitch (often the song's root), and it sustains for hundreds of milliseconds — much longer than an acoustic kick.

Translating the 808 to an acoustic kit means accepting that you cannot reproduce it. You can, however, voice it. A floor tom — tuned low, with the resonant head loose — gives you a long-decay low note. A second kick drum, if you have one, can be detuned to do the same. A combination of acoustic kick and electronic trigger is the modern compromise. The notational convention in this lesson uses the floor tom as the 808 voice and the bass drum as the percussive layer.

Voice Mapping

  • Bass drum (f/4) — the kick layer (short, percussive transient).
  • Floor tom (a/4) — the 808 layer (long, low, sub).
  • Hi-hat (g/5/x2) — the trap hat line, often rolling.
  • Snare (c/5) — backbeat (often on 3 in a half-time trap feel — the second backbeat).

Half-Time Counting

Trap is usually written and felt at half the BPM of the underlying hat roll. A hat playing apparent 16ths at 140bpm is actually playing 32nds against a 70bpm pulse. The snare on 3 — what would be beat 3 at full tempo — is the backbeat. This lesson is notated at the half-time pulse so the snare feels like a 2-and-4 backbeat in a slow song.

Exercises

1 — Basic 808 Pattern (Kick Only)

4/4 (half-time feel) · ♩ = 70
808 kick pattern voiced on the bass drum only. Kick on 1, the &-of-2, the &-of-3 and 4. That &-of-3 is the anticipation. The snare is on 3 — the half-time backbeat. This sparse syncopated kick line is the shape; in exercise 2 we'll add the floor tom as the 808-sub layer. Practice this until the kick pattern is locked. The kick must not drift toward 1-and-3 on autopilot — every 808 hit lands deliberately.

2 — Floor-Tom-as-808 Sub Layer

4/4 (half-time feel) · ♩ = 70
The floor tom doubles every kick note, right hand and right foot landing as one — that alignment is the whole challenge, and dropping to ♩=55 to get it clean is legitimate. Locked, the pair reads as a single 808: transient on top, sub underneath. Flammed, it reads as two drums.

3 — Canonical 16th Hat-Roll Over an 808 Pattern

4/4 (half-time feel) · ♩ = 70
The 16th hat is the engine — if it stumbles, the groove dies. Build in layers: hat alone, then the snare on 3, then the kick pattern. The likely fail point is the &-of-3, where a kick lands mid-roll and the temptation is to drop a hat note. Don't.

4 — Four-Bar 808-Driven Groove

4/4 (half-time feel) · ♩ = 68
The rolling-hat gesture on the &-of-4 — 32nds, sticking R-L-R-L — is the hard part; start at ♩=50 and creep up. Around it: snare on 3 and the busy kick line (1, &-of-2, the 16th syncopation, &-of-3, &-of-4). The roll signals the section repeat, so it can't smear.
Move on when
  • Basic 808 kick pattern (long-decay sub on syncopated 16ths) holds at ♩=70 (half-time feel) for 16 bars
  • Floor-tom-as-808 voicing is clearly distinguishable in pitch from the kick on every bar
  • Canonical 16th hat-roll over an 808 pattern sustains for 8 bars without the roll falling apart on the &-of-3
  • 4-bar 808-driven groove is repeatable on demand with the same kick/sub voicing each time
Listening 3 records

Listen for it

  1. 01

    Various producers Travis Scott — Astroworld

    No drum credit appears anywhere in the personnel — the played instruments are keyboards, guitar, bass, cello and strings, so every kick and 808 here was programmed. More than twenty producers worked on the album, so listen for how the 808 tuning and decay shift from track to track.

  2. 02

    Metro Boomin Heroes & Villains

    The personnel credit here is programming, not performance, so every kick and hat on the record was built rather than struck. Listen for how the live strings, trumpet and French horn sit against drums that no one played.

  3. 03

    Tay Keith BlocBoy JB — Look Alive

    One producer built this entire instrumental, so the 808 line and the hat rolls come from a single author rather than a committee. Eminem's Not Alike interpolates the same beat, which lets you hear the pattern land in two different settings.
