Trap drums are sparse where hip-hop is busy, and busy where it's sparse. Understanding that inversion is the whole thing.
Trap is written at around 140 BPM but felt at 70. The snare lands on beat 3 only, rather than on 2 and 4.
That single choice creates the genre's signature: slow, heavy backbone with fast detail on top.
Over one bar at 140:
- Kick: syncopated, sparse, often on 1 and somewhere in the second half of the bar. Not steady.
- Snare or clap: beat 3.
- Hi-hats: 8ths or 16ths as the base, with rolls.
- 808: following the kick, tuned to the key.
The most recognisable element. A roll is a burst of fast subdivisions — 32nds, 64ths, sometimes triplets — usually at the end of a bar or leading into a section change.
How to make them sound performed:
- Vary velocity across the roll. Ramp up into the next downbeat, or ramp down. Flat velocity sounds like a computer.
- Vary the subdivision. Mixing 32nds and triplets inside one roll is much more interesting than a uniform burst.
- Pitch the hats slightly across the roll for movement.
- Don't overdo it. One or two rolls per four bars. Constant rolls become noise.
The 808 is bass and kick simultaneously, and it must be tuned to the key. An untuned 808 makes the whole track sound wrong in a way people can't name.
Glide (portamento) between notes creates the sliding effect. Set a short glide time and overlap the notes — the slide only happens between overlapping notes.
Length matters. Long 808s create sustained bass; short ones punch. Vary them across the pattern.
Saturate it. A pure sine 808 is inaudible on phone speakers. Saturation or distortion adds harmonics higher up the spectrum, so the note is still perceived when the sub isn't reproduced. This is essential, not optional.
Sidechain the 808 to the kick if you're layering a separate kick, or the two will cancel each other in the low end.
Trap is defined as much by what isn't there. Long gaps, single elements, sudden drops to just an 808. If your trap beat feels cluttered, delete something.
Generated patterns tend to be too even and too busy. The fixes: sparsen the kick, put the snare on 3 only, add velocity curves to the rolls, tune and saturate the 808.
