Rapcore, rap at 92 BPM, built around a tense minor-key piano ostinato, gritty electric bass, and tight boom-bap drums with crisp snare cracks and swung hi-hats. Give each verse a distinct, confrontational cadence, with clipped phrasing, sharp pauses, and close-miked delivery; layer subtle doubles and brief delay throws. The hook opens into wider synth chords and heavier kicks, then drops back to a sparse beat.
