How to make boom bap in your browser

By Tongkit Leong · August 20, 2026 · 8 min read

Boom bap is built from a chunky, swung kick-and-snare break, a chopped soul or jazz sample looped into a hook, and a dusty, lo-fi texture on top — all sitting around 85 to 95 BPM — and you can program all three from scratch in the Tracks browser studio in an afternoon, with no software to install and no account to create.

The anatomy of a boom bap track

Boom bap gets its name from the sound of its two most important drum hits — a booming kick and a snappy, cracking snare (the "bap") — and it's the production style that defined East Coast hip-hop through the late '80s and '90s. Modern producers still reach for it because it's built from a small number of clear, deliberate parts:

• A tempo around 85 to 95 BPM — slower and heavier-feeling than trap or drill, closer to a relaxed walking pace than a rush.
• A chunky, swung drum break — a kick and snare with real weight behind them, played with enough swing that the groove leans back instead of sitting dead-on-grid.
• A chopped sample loop — a short phrase pulled from a soul, jazz, or funk record, sliced into pieces and reassembled into a new melodic hook rather than looped whole.
• A simple, supportive bassline — usually just the sample's own root notes reinforced, not a separate melody competing for attention.
• A dusty, lo-fi texture — the crackle, hiss, and slight distortion of a sampled vinyl record, often added on purpose even when the source is digital.

Tracks has what you need for this built in — the drum machine for the break, the 16-pad sampler for chopping and flipping a sample, a subtractive synth for the bassline, and the bitcrusher for the dusty top end.

Step 1: Set your tempo

Open the Tracks studio and set the BPM in the transport bar to somewhere between 85 and 95. Slower boom bap, closer to 85, tends to feel heavier and more head-nodding; faster boom bap, closer to 95, feels a touch more urgent without ever approaching the energy of trap or drill. Pick a number in that range and stay there — boom bap doesn't use tempo changes within a track.

Step 2: Program the chunky, swung drum break

Add a track and open the drum machine. Start with a kick on beat one and a snare or clap on beat three — the classic "boom... bap" backbone — then layer in a steady 8th or 16th-note hi-hat pattern underneath. Keep the kick and snare simple and let their tone do the work rather than piling on extra hits.

Swing is what separates a boom bap break from a stiff, modern trap pattern. Push the hi-hat swing up so the off-beat hats land slightly late instead of exactly on the grid — this is what gives the classic MPC-sampler "head-nod" feel. See Quantize and swing explained for how much swing to dial in and why it makes a static pattern feel human.

Drum tone

Boom bap kicks and snares are usually punchy and a little compressed rather than clean and hi-fi — a short, tight kick and a cracking, slightly saturated snare read more authentic than a modern, ultra-clean drum sound. Light compression on the drum bus helps glue the kick and snare together into one solid hit.

Step 3: Chop and loop a soul or jazz sample

Add a new track and open the 16-pad sampler. Load a sample — a soul, jazz, or funk phrase with some harmonic movement works best — and chop it into short slices at the sampler's natural breakpoints: a chord change, a horn hit, a vocal phrase. Assign each slice to a pad so you can trigger them in a new order.

This is the "flip" — rearranging the chopped slices into a new 2- or 4-bar loop that didn't exist in the original recording. Reordering pieces, repeating a favorite slice, or dropping one out entirely all count. See How to chop and flip a sample for the full mechanics of slicing, pad-mapping, and building a loop this way in Tracks.

Keeping the chop in time

If the source sample's tempo doesn't match your project BPM, use time-stretching to bring it into the pocket before you chop it, so every slice lines up cleanly with your drum break. See Time-stretch and repitch explained for how that works without changing the pitch.

Step 4: Add a simple bassline

Add a synth track and keep the bassline deliberately plain — its job is to reinforce the sample's own low end and lock to the kick, not to introduce a new melody. Open the piano roll and write a part that mostly follows the sample loop's root notes, landing right on or just after each kick hit.

See How to lock a bassline to the kick for the mechanics of keeping bass and kick from smearing into each other in a low-tempo groove like this one.

Step 5: Add a dusty, lo-fi texture

Part of the boom bap sound is the texture of an old sampler chewing on a vinyl record — crackle, a slightly narrowed frequency range, and a touch of grit. Add a bitcrusher to the sample track and dial it in gently; you're after character, not obvious digital distortion. A little saturation or light high-frequency roll-off on the same track pushes it further toward "sampled record" and away from "clean digital file." See Creative FX: chorus, phaser, and bitcrusher for how to dial in texture effects without overdoing them.

Keep this treatment on the sample loop, not the drums or bass — dirtying up the whole mix at once tends to just sound muddy rather than vintage.

Step 6: Arrange the track

Boom bap arrangements are usually loop-based and built around the sample flip rather than a long, evolving structure. A dependable shape looks like this:

1. Intro (4–8 bars): drums alone, or drums with a stripped-down version of the sample loop, to establish the groove.
2. Verse (16 bars): the full loop — drums, sample, and bass together — repeating with minimal variation under a rap vocal or as a standalone instrumental.
3. Hook (8 bars): a variation on the sample flip, a different chop order, or a filtered-down version for contrast.
4. Breakdown (4 bars): drop the drums out and let the sample loop play alone before the next verse re-enters.
5. Outro (4–8 bars): fade or strip elements back to just the drum break.

See How to arrange a song for building sections like these from scratch on the Tracks timeline.

Step 7: Mix and export

Before you export, spend a few minutes balancing levels in the Tracks mixer:

1. Balance the kick and bass first — with a low tempo and few elements, a weak low end is the fastest way for a boom bap beat to feel thin.
2. Make sure the sample loop and drum break feel locked together rather than fighting for the same frequency range; a little EQ carving on the sample around the kick's fundamental usually fixes this.
3. Keep the overall mix a touch darker and less bright than a modern pop mix — boom bap leans warm, not glossy.
4. Use the mixer's group buses if you're layering multiple drum or sample tracks, so you can balance the whole break against the whole sample loop as two units. See Mix group buses and sends explained.

When the balance feels right at a comfortable volume, export to WAV for a clean master file or MP3 to share online — see How to export your song to MP3 or WAV for the full walkthrough. Your project stays in your browser the entire time; Tracks never uploads it anywhere.

Frequently asked questions

What BPM is boom bap?

Most boom bap sits between 85 and 95 BPM. That's noticeably slower than trap or drill, which is part of why the genre feels heavier and more head-nodding rather than urgent.

Do I need an actual vinyl sample to make boom bap?

No. The genre's texture comes from technique, not source material — chopping a phrase into new slices, adding swing to the drums, and applying a bitcrusher or light saturation will get you most of the way there even starting from a clean digital sample or a part you played yourself.

Why does my chopped sample sound out of time with the drums?

Usually a tempo mismatch between the source sample and your project. Time-stretch the sample to your project BPM before you chop it, so every slice already lines up with the grid instead of drifting against the drum break.

How much swing should I use on a boom bap beat?

Enough that the hi-hats clearly sit behind the beat rather than dead-on-grid, but not so much that the groove starts to feel unstable. Start around a moderate swing amount and adjust by ear against the kick and snare — see Quantize and swing explained for reference amounts.

Can I make boom bap without a rap vocal?

Yes. Boom bap instrumentals are a complete genre on their own and are commonly released and played without any vocal at all. A finished, mixed instrumental built in Tracks is a valid end point, and also a solid base if you later want to record a vocal over it.
