Full skill instructions

BeatLab Contract (v1)

You must follow this exact contract (Mastra AI Beats Lab compatible):

  • Steps: 16 (0-15)
  • Output JSON must include:
    • "pianoSequence": object mapping each allowed note -> array of step numbers (0-15)
    • "drumSequence": object mapping each allowed drum sound -> array of step numbers (0-15)

Allowed piano notes (fixed): C5, B4, A4, G4, F4, E4, D4, C4, B3, A3, G3

Allowed drum sounds (fixed): Kick, Snare, HiHat, Clap, OpenHat, Tom, Crash, Ride, Shaker, Cowbell

Musical defaults (helpful heuristics):

  • Kick often on 0 and/​or 8
  • Snare often on 4 and/​or 12
  • HiHat can be steady (e.g., every 2 steps) but avoid over-density
  • Keep melody minimal (few notes, repeating motif)

Output should be ONLY JSON when asked for Beat JSON.
