To make a lofi beat, set the tempo between 70 and 90 BPM, write a jazzy progression built on seventh chords, add a sparse melody, program a swung boom-bap drum pattern, keep the bass on simple roots, then bury the whole thing in texture: vinyl crackle, tape wobble, and a low-pass filter. The chords and the swing do most of the work; the texture layer is what makes it read as lofi instead of just slow hip hop.
Step 1: Tempo and key
Start at 80 BPM. The genre lives between 70 and 90, and anything above 90 starts to feel like boom bap instead of study-playlist material. Keys with flats feel at home here, but any key works. What matters more than the key is the chord quality: lofi runs on sevenths and ninths, not plain triads.
Step 2: Chords
The classic lofi move is a jazz turnaround. In C major: Dm7 (D, F, A, C) to G7 (G, B, D, F) to Cmaj7 (C, E, G, B) to Am7 (A, C, E, G). That is a ii-V-I-vi, and it loops forever without getting old. Play it on an electric piano or soft keys, keep the voicings in the middle of the keyboard, and drag some notes a few ticks off the grid so it sounds played rather than programmed.
If jazz voicings are not in your fingers yet, this is the honest shortcut: start from a MIDI file a real composer wrote, then make the sound and groove choices yourself. The lo-fi MIDI packs are built for exactly this, and Lofi Beats Vol.1 is the place to start. For the theory behind the voicings, read lofi chord progressions.
Step 3: Melody
Lofi melodies are more of a comment than a statement. Take 3 to 5 notes from the chord tones, play a short phrase, then leave a bar of space. Muted guitar, kalimba, soft saxophone, or the same keys patch an octave up all fit. Lower the velocity: melody notes in lofi should sit behind the chords, not in front of them. If a phrase feels too polished, nudge one note late and shorten another. Imperfection is the aesthetic here, and the piano roll grid is your enemy.
Step 4: Drums and swing
Program a simple boom-bap skeleton first: kick on beat 1 and the "and" of beat 2, snare on beats 2 and 4, hats on 8th notes. Then apply the two changes that make it lofi:
- Swing at 55 to 65 percent. This delays every offbeat hat and gives the drunk, head-nod feel. Straight 50 percent swing is the most common reason a lofi beat feels stiff.
- Soft, dusty samples. A snare that cracks like a trap clap is wrong here. Pick muffled kicks and snares, or low-pass the drum bus around 6 to 8 kHz.
Step 5: Bass
Keep it humble. Play the root of each chord (D under Dm7, G under G7) as long, soft notes, one or two per bar. An upright bass patch or a round sine bass works. Lofi bass supports; it never leads. If you want one flourish, add a short walk-up into the next root at the end of a bar, once per loop, and leave the rest alone.
Step 6: The texture layer
This is the signature step. Add at least two of these: vinyl crackle, tape hiss, rain or cafe ambience, and subtle pitch wobble on the keys (a slow chorus or a tape emulation plugin). Then low-pass the whole mix gently, around 10 to 15 kHz. A rule of thumb worth keeping: if the beat sounds slightly broken, it is finished.
Step 7: Arrangement and rough mix
Lofi arrangements are loops with breathing. A workable map: 4-bar intro (chords plus crackle), 16 bars full, 8 bars with the drums dropped, 16 bars full again, 4-bar outro. For the mix, keep the drums quieter than you would in hip hop, let the chords be the loudest element, and check the low end in mono so the bass and kick do not blur.
Skip the blank piano roll
The one thing MIDI cannot do is the texture and swing work: that is your taste, and it is the fun part. What it can do is hand you a progression that already sounds like a record. FFUNK files are written by composers with Gold and Platinum records, you can audition every file in the browser first, and Key Sync transposes downloads to your working key automatically.
