How to make boom bap drums

Gazillion Industries ·

A lot of boom bap was made in basements with carpet stapled to the walls, on drums lifted off records that were already old when somebody first looped them. The sound is the room, the dust and the swing, and none of it came with a preset.

To make boom bap drums, start with punchy, slightly dusty sounds (chopped breaks or one-shots), program a simple pattern around 80 to 100 BPM with the snare on 2 and 4, add swing so the groove leans, then process the kit as a whole: filter the samples, squash the drum bus with compression, add saturation for density, and leave some room sound in. Keep it simple; the pocket matters more than the parts.

The short version

Tempo
roughly 80 to 100 BPM
Sounds
chopped breaks or dusty one-shots
Pattern
kick on 1, snare on 2 and 4, hats in eighths
Swing
enough that the hats lean
Bus
compression for squash, saturation for density
Texture
filtered highs and lows, some room left in

What boom bap drums are

The name is the sound: the boom of the kick and the bap of the snare, heavy and upfront, usually over sampled music. The drums are typically either a break sampled from a record or individual hits taken from one, which is where the dust and character come from, and they sit at a relaxed tempo where the snare has room to crack.

A starting pattern

In a bar of sixteen steps, this is a common place to start:

Kick
steps 1 and 11, with a pickup on 8 or 9 for variation
Snare
steps 5 and 13 (beats 2 and 4)
Hats
every odd step (eighth notes), with swing

Then break it: move a kick, drop a hat, add a ghost note before the snare. The best boom bap patterns sound like someone played them, not like a grid.

Swing is the pocket

Straight eighths sound stiff. Push the offbeat hats late with your DAW's swing or groove setting until the beat leans back, then nudge individual hits by hand. Slightly late snares feel lazy in a good way; slightly early ones feel anxious. Chopped breaks bring their own swing, so match your programmed parts to the break rather than to the grid.

Process the kit as one

Boom bap drums sound like a single performance because they're treated like one. Route everything to a drum bus. Low-pass the samples a little to take the digital sheen off the top, and high-pass anything below the kick's body. Compress the bus until it squashes and the room comes up (drum bus compressor settings has the numbers), then add saturation for density (how to saturate drums).

BEEFY is for a break that needs to stop being so polite. The demo on the page is 28 seconds.

How to make boom bap drums, step by step

  1. Set the tempo between about 80 and 100 BPM.
  2. Load a chopped break, or kick, snare and hat one-shots with some grit.
  3. Program the starting pattern above and add swing to the hats.
  4. Nudge a few hits off the grid by hand.
  5. Route the drums to a bus; low-pass and high-pass gently.
  6. Compress the bus for squash, then add saturation.
  7. Soft clip the loudest hits so the drums can sit up front.
  8. Compare with a reference at matched loudness.

Structure

Boom bap beats are usually a four- or eight-bar loop that changes by subtraction: drop the kick for the intro, pull the drums out for a bar before the hook, strip back to kick and snare under a verse. The drums hold the song together; the changes keep the rapper interested.

Questions people ask

What drums are used in boom bap?

Punchy kicks and cracking snares, usually sampled from old records, either as a full break or as individual hits, with hats or a shaker. The character comes from the sampled source and from heavy bus compression and saturation.

What is the drum pattern for a boom bap beat?

A common starting point is the kick on the first beat and the "and" of the third beat, the snare on beats 2 and 4, and swung eighth-note hats, at around 80 to 100 BPM. Variations on the kick placement give each beat its bounce.

How do I structure a boom bap beat?

Build a four- or eight-bar loop, then arrange by taking things away: an intro without drums or kick, drop-outs before the hook, and lighter drums under verses. Most of the arrangement is subtraction.

What BEEFY does

BEEFY is our saturation and loudness plugin. On a drum bus it pulls the hits and the body closer together, and it's there for a break that needs to stop being so polite. BEEF adds weight, density and loudness, COOK moves the tone from rounder toward brighter and more bitten, and SOFT CLIP, on by default, rounds off the loudest hits.

No carpet on your walls, probably. The drums can still sound like there is.
