Disco

Build everything off a four-on-the-floor kick at 120 BPM and let an open hi-hat hit every offbeat (the '+' of each beat) to create that signature lift. Bass is the engine here: write a busy, octave-jumping or syncopated bassline that locks tight to the kick rather than just holding root notes. Keep the snare or clap on beats 2 and 4, and reserve syncopated 16th-note hats and percussion for the breakdowns. For nu-disco, push slightly faster toward 122 BPM, lean into sidechain compression, and swap live strings for warm analog-style synths and filtered chords. Layer string stabs, guitar 16ths, and brass risers to fill the mid-range without crowding the bass.

Disco tracks typically run long with an extended intro, verse-chorus sections, and a stripped breakdown that drops to bass, hats, and percussion before the full arrangement returns. The extended outro is built for DJ mixing, keeping the groove going well past the final vocal.
