To make a trap beat, set your tempo between 130 and 160 BPM, pick a minor key, write a dark two-to-four chord progression, add a simple melody on top, program half-time drums with rolling hi-hats, then give the 808 its own bassline that follows the chord roots. Arrange it into intro, verse, and hook sections, and finish by making sure the kick and 808 are not fighting each other. That is the whole recipe. The rest of this guide walks through each step with concrete numbers.
Step 1: Tempo and key
Start the project at 140 BPM. Almost all trap lives between 130 and 160, and 140 is the safe center. Trap is felt in half time: the snare lands on beat 3 instead of beats 2 and 4, so a 140 BPM beat grooves like a 70 BPM song. That is why trap can be fast on the grid and slow in your chest at the same time.
Pick a minor key before you write a single note. C minor, F minor, and G minor are the workhorses. Everything you write from here, chords, melody, and 808, should stay inside that key.
Step 2: Chords
Trap harmony is simple and dark. Two to four chords, minor, looping every 4 or 8 bars. In C minor, try Cm (C, Eb, G) to Ab (Ab, C, Eb) to Eb (Eb, G, Bb) to G (G, B, D): the raised B in that last chord comes from the harmonic minor scale and gives you the tension trap loves. Keep the voicings low-mid and let them ring as pads, bells, or dark keys.
Here is the honest shortcut: this step is where most beats die, and it is the one step you can legitimately outsource. Start from a composer-written MIDI progression, drag it in, pick your own sound, and move on. Browse the trap MIDI packs or go straight to DARK TRAP Vol.1. If you want to learn the theory behind these moves, read dark trap chord progressions.
Step 3: Melody
Write the melody from the notes of your chords, one octave above them. Trap melodies are short: a 2-bar phrase that repeats, often with heavy space between notes. A bell, a plucked keys patch, or a detuned flute all work. Do not overwrite it. If your melody has more than 8 to 10 notes per 2 bars, cut some.
Step 4: Drums
Program in this order:
- Snare or clap on beat 3 of every bar. This single placement creates the half-time feel.
- Hi-hats on straight 8th notes as the base layer. Then add rolls: switch short sections to 16th notes, 32nd notes, or triplets. One roll every 2 bars is plenty.
- Kick pattern with syncopation. Beat 1 is the anchor; the rest of the kicks land off the grid lines, usually 2 to 4 hits per bar. Leave gaps.
- Percussion accents like an open hat on the offbeat or a rim every 4 bars.
Step 5: The 808
The 808 is the bassline, not a sub-thump under the kick. Write it as notes: follow the root of each chord (C under Cm, Ab under Ab, and so on), copy your kick rhythm as the starting point, then add one or two slides between roots for movement. Tune the 808 to the key, always. An out-of-tune 808 will make a correct progression sound wrong.
Step 6: Arrangement
Trap arrangements are built from 8-bar blocks. A standard map: 4 to 8 bars of intro (melody alone or filtered), 16-bar verse (full drums, 808), 8-bar hook (add a layer, open the filter), second verse, second hook, 4-bar outro. Create contrast by removing elements, not adding them: drop the 808 for the last 2 bars before the hook and the hook will hit twice as hard.
Step 7: Mix basics
Two moves cover most of a trap rough mix. First, resolve the kick vs 808 clash: either sidechain the 808 to the kick or cut the kick below 40 Hz and let the 808 own the sub. Second, keep the melody and hats out of the 808's way with a high-pass filter around 200 to 300 Hz on everything that is not bass or kick.
Start from real chords, finish faster
A MIDI file will not mix your beat or program your hats for you: that part is still your job. But it removes the blank piano roll, which is the step that actually stalls sessions. FFUNK progressions and melodies are written by composers with Gold and Platinum records, and Key Sync delivers every file already transposed to your working key.
