orbits that play piano / strings bowed by finger / drawings that sing
Instruments should fight back a little. We hang music on physics — flung orbs, bowed strings, wind, ink — and you curate what it sings.
A tiny solar system that plays piano. Fling orbs, bend their orbits with a draggable gravity well, and let the ricochets land in key — you set up the conditions; the physics does the playing.
No keys, no samples — your finger is the bow. Where you touch is the note, how fast you move is the stroke, and it squeaks if you lean on it. Real violins are also like this.
The sequencer with no piano roll. Paint rectangles — where one sits is when and what it plays, its size is how long and how loud. Four colors, four voices, one canvas.
Ink is the score. Draw strokes and beams of light read them back — pitch from where you drew, timing from when the beam arrives. The audience sees every note at the moment they hear it.
