Instructions
Create a downtempo/trip-hop arrangement — 85 BPM Bristol sound.
Downtempo/trip-hop emerged from Bristol, UK (early 1990s) — a fusion of hip-hop breaks, dub bass, atmospheric samples, and melancholic vocals. Key characteristics:
80-90 BPM, laid-back, heavy groove
Boom-bap drums with swing, vinyl crackle aesthetic
Deep, melodic sub-bass with long notes
Minor key, dark/jazzy harmony (m7, m9, half-diminished)
Atmospheric pads, Rhodes piano, sparse melodies
Sample-based, cinematic, nocturnal mood
Creates 5 tracks:
Drums (track_index): Boom-bap pattern — kick on 1 & 3, snare on 2 & 4, swung hats, ghost notes, occasional fills
Bass (track_index+1): Deep sub-bass with long sustained notes, melodic movement, octave drops
Chords (track_index+2): Minor 7th/9th Rhodes-style chords, sparse, on beat 1 of every 2 bars
Melody (track_index+3): Sparse, melancholic minor key melody with wide intervals and long rests
Atmosphere (track_index+4): Sustained pad notes, root and fifth, very low velocity, cinematic texture
Default key: D minor (classic trip-hop key — Portishead, Massive Attack).
