How to make drill music in your browser

By Tongkit Leong · August 5, 2026 · 8 min read

Drill runs on an off-beat kick pattern, a sliding 808 bassline, and triplet hi-hat rolls, all sitting in a sparser arrangement than most trap-adjacent genres — and you can program all of it from scratch in the Tracks browser studio with no software to install and no account to create.

The anatomy of a drill beat

Drill shares some DNA with trap — the sliding 808, the half-time snare, the minor-key darkness — but a handful of details set it apart:

• Off-beat kick placement — kicks land in short, syncopated clusters that dodge the downbeat rather than anchoring it, leaving deliberate silence around the snare.
• Triplet hi-hats — instead of straight 16th-note grids, hats are grouped in threes, giving the beat a rolling, slightly lopsided swing that's the clearest fingerprint of the genre.
• Sliding 808 — the same gliding bass tone trap uses, but often held longer and left more exposed, since drill arrangements leave it more room to breathe.
• Sparse, cold arrangement — drill tends to strip elements out rather than pile them up, favoring space and tension over density.
• Dark string or piano melody — short minor-key phrases, often orchestral or piano-based rather than synth plucks, played with noticeable gaps rather than a continuous loop.

Tracks covers all of it out of the box — the 808/909 drum machine for the kick and hats, a subtractive synth for the sliding bass, a piano roll for writing every part, and a mixer with sidechain ducking to keep the low end under control.

Step 1: Set your tempo

Open the Tracks studio and set the BPM in the transport bar.

• Typical range: 130–150 BPM, which most drill producers write and hear as 65–75 BPM in half-time.
• 140 BPM is a solid, genre-typical default if you're starting from scratch.
• Writing at the doubled tempo (rather than the felt half-time tempo) makes it easier to place triplet hi-hat subdivisions precisely on the grid.

Lock the tempo in before programming hats — the triplet feel only reads correctly once the grid and the felt pulse line up.

Step 2: Program the off-beat kick and snare

Add a track and open the drum machine. On a 16-step grid representing one bar, place the snare or clap on step 9 — beat 3 — the same half-time anchor trap uses. This single placement sets the foundation; everything else is built around it.

Where drill diverges from trap is the kick. Instead of a steady, evenly syncopated pattern, place kicks in short clusters of two or three quick hits that land ahead of or behind the beat, then leave a noticeable stretch of the bar with no kick at all. That silence is intentional — drill kick patterns read as unpredictable and a little off-balance on purpose, rather than locking into a repeatable groove the way a house or trap kick does. Loop just the kick and snare and listen for gaps that feel like held breath rather than a steady pulse.

Step 3: Program triplet hi-hat patterns

This is the single most identifiable element of a drill beat. Instead of filling the 16-step grid with straight subdivisions, group your hi-hat hits in threes — a triplet feel — so the hats roll unevenly against the underlying 16th-note grid instead of ticking in lockstep with it.

A common approach: place a hi-hat, skip a fraction of a step, place another, skip again, place a third, then rest before the next triplet group starts. If your version of Tracks' step grid is set to straight 16ths, you can approximate the same feel by grouping three consecutive quick hits together and leaving the next one or two steps empty, repeating that three-hits-then-rest shape across the bar. Taper the velocity down slightly across each triplet group so it rolls rather than sounding like three identical clicks.

Open hats and rests

Use open hi-hats sparingly — one per bar is usually enough — to punctuate the end of a triplet run. Leave real silence between hi-hat groups rather than filling every gap; the space is as much a part of the drill hi-hat sound as the triplets themselves.

Step 4: Write a sliding 808 bassline

Add a new instrument track and open the subtractive synth. Set the oscillator to a sine wave, with a touch of saturation from the distortion effect if you want extra grit, and keep the filter open so the low end stays full.

Open the piano roll on the 808 track and write a bassline that follows your chord progression's root notes. Where drill differs from trap is duration — let 808 notes ring out across a full bar or more rather than chopping them up, and use pitch glides between notes a semitone or wider apart so the transitions slide instead of cut. A drill 808 often carries a section almost entirely on its own, with the kick pattern built around it rather than the other way around.

Leaving room for the kick pattern

Because the kick clusters in step 2 are syncopated and sparse, make sure your 808 note changes don't collide with a kick hit — offset them by a sixteenth note where they'd otherwise land together, so the low end reads as one coherent movement instead of two competing hits.

Step 5: Add a dark string or piano loop

On a separate track, use a string patch, an FM bell tone, or a minor-key piano SoundFont for the melodic layer. See SoundFont instruments explained for loading a realistic string or piano sound instead of a fully synthesized one. Drill melodies tend to favor minor and Phrygian-flavored scales — the same flattened second and sixth degrees that give trap its tension work here too, often with a more orchestral, cinematic color.

Write a short two- to four-note phrase and, unlike a continuously looping trap pluck, leave real gaps between repetitions of the phrase rather than looping it back to back. That space is part of what makes drill feel colder and more spacious than trap even at a similar tempo.

Step 6: Arrange with sparse space

Drill arrangements generally stay sparser for longer than trap arrangements do. A workable structure:

1. Intro (4–8 bars): string or piano loop alone, maybe with the 808 entering late, no drums yet.
2. Verse (8–16 bars): kick and snare pattern enters, triplet hats stay minimal at first.
3. Build (2–4 bars): hi-hat density increases, but resist the urge to add many more layers — drill builds tension through rhythm more than through stacking new elements.
4. Hook (8–16 bars): full kick, snare, hat, 808, and melody together, still leaving audible gaps rather than filling every beat.
5. Breakdown (4–8 bars): strip back to 808 and melody before the final section.

Use the Tracks timeline to duplicate sections and mute individual tracks so you can compare a sparser arrangement against a fuller one before committing — with drill, the sparser version is usually the right call.

Step 7: Mix and export

Before exporting, balance levels in the Tracks mixer:

1. Compress the 808 with a moderate ratio and a slower attack so the front of each slide stays punchy while the sustained tail evens out.
2. If the 808 and kick clash, add a light sidechain duck on the 808 triggered by the kick — see Sidechain compression explained for how to set it up in Tracks.
3. Keep an ear on the triplet hi-hat runs; fast clustered hits can clip if they're too hot. A limiter on the drum bus or master track keeps the peaks in check.
4. Send the string or piano loop to a reverb bus for atmosphere, but keep the wet level moderate so the phrase stays defined against the sparse arrangement.

Once the balance feels right, 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 whole time; Tracks never uploads it anywhere.

Frequently asked questions

What BPM is drill music?

Most drill sits between 130 and 150 BPM on the grid, with 140 BPM a common default, similar to trap. Because of the half-time snare and off-beat kick, it's usually felt closer to 65–75 BPM — the difference from trap is more about the triplet hi-hat feel and sparser arrangement than the tempo itself.

What makes drill hi-hats sound different from trap hi-hats?

Drill hats are grouped in triplets rather than straight 16th-note rolls, which gives them a rolling, slightly uneven feel instead of a smooth, evenly accelerating roll. Combined with more rests between groups, this triplet pattern is the fastest way to tell a drill beat apart from a trap beat at a glance — or a listen.

Do drill and trap use the same 808 technique?

Yes — both rely on a sliding sine-wave bass built with pitch glides between notes in the piano roll. The main difference is how it's used: drill 808s tend to hold longer notes with more space around them, letting the bass carry a section largely on its own, while trap 808s often move more actively alongside a busier drum pattern.

Do I need real drill drum samples?

No. Tracks' built-in 808 and 909 drum machines cover the kick, snare, clap, and hi-hat sounds drill is built on, and the sampler lets you load your own one-shots if you want a specific tone. Drill is defined much more by its rhythm — the off-beat kicks, the triplet hats, the space between hits — than by any particular sample pack.
