🎵 AI Jam Session

Generate an 8-bar jam using constraint-based algorithms. Pick a preset and hit play.

🎹 Constraint Piano

Play a virtual piano where keys snap to lattice positions. Toggle snap on/off to hear the difference. See the A₂ lattice grid overlay in real time.

Sweet Spot Under-constrained Over-constrained

📊 Flow Hypothesis

The Goldilocks curve of musical constraint. Too few constraints = boring. Too many = chaotic. The sweet spot produces flow states.
