Marble Music Track Turns a Falling Marble Into a Musical Sequencer

Field notes

Marble Music Track uses a fixed marble path as both sequencer and performance: notes are placed on a canvas, then triggered in order as the marble falls and moves across rails. The page lists four instrument families—marimba, glass, glockenspiel, and kalimba—plus thirteen visual styles. A scale lock is intended to keep placed notes compatible, while saved machines, undo, pan-and-zoom, and vertical video export support repeated experimentation on a mobile device.
