๐ŸŽต AI Jam Session

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

๐ŸŽน Constraint Piano

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

๐ŸŽน Tensor MIDI โ€” Conservation in Music

Spectral conservation theory applied to harmony. The Conservation Ratio measures how well harmonic patterns preserve spectral energy โ€” real music scores CRโ‰ˆ0.87-0.94, random notes score CRโ‰ˆ0.25-0.35.

iiโ€“Vโ€“I in C:
CR=0.94 (+4.06ฯƒ)
12-bar blues:
CR=0.87
Random notes:
CR=0.31

Sweet Spot Under-constrained Over-constrained

๐Ÿ“Š Flow Hypothesis

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