Sing into a scale that has no octave

Hum or sing into the mic. Your voice is tracked and snapped onto a Bohlen–Pierce lattice — a 13-tone scale that repeats not at the octave but at the tritave (3:1), built on odd harmonics. Every node you land on lights up, glides a tone to meet you, and rings its harmonic neighbours sympathetically until the room blooms into a strange, gorgeous chord.
