Handsong tech demo

The first open version of the instrument, where it all began. It shows what hands and a camera can do — no painted world, only sound.

Best on a laptop with Chrome · the camera image never leaves your device

Who it's for

For curious musicians and anyone who wonders how an instrument without an instrument works: modes from around the world, unusual tunings, two-handed play.

What's inside

Dozens of modes and sounds, effects on the second hand. One hand plays the notes, the other shapes the sound: echo, brightness, wave.

What's next

The full Handsong — with an editor, recording and saving your melodies — is in the works. The tech demo stays open until it's out.
