Piano Phrase Painter

Karel's real piano recording listens to itself — onset detection, harmonic chromagram, and phrase-boundary analysis drive when a new image is dreamed and what it depicts. The returning image bends the piano back. A closed audio → image → audio loop that follows musical structure.

No audio file? Begin plays Karel's Ghost-journey recording (when logged in) or a warm synthesized piano that resolves on purpose — both drive real musical analysis.
