Resonance Cube

Resonance Cube is a perpetual music machine inspired by modern composers. Tap the cube to add balls that bounce and play — each one a note in a living, evolving chord. As the music plays, the colors respond.

Choose your key, chord, and instrument to shape the sound. Pick from vibraphone, piano, Rhodes, gamelan, warm pad, or crystal bowl.

Let a curated chord sequence play automatically, or explore freely in Free Play mode. Add up to 24 voices — 12 melodic, 12 pad — and watch the composition build. When the cube is full, tapping begins to subtract, winding the music back down.
