Compass Theremin

The Compass Theremin is a sensor-based music instrument which uses readings from your phone's gyroscope (compass), to control the pitch of a synth oscillator.

Simply put - to play this instrument you hold your phone and turn it around in different directions, or alternatively hold it in one direction and turn around yourself.

It's a lot of fun and you'll get the hang of it very quickly.

You can choose between different scales, attack / release times, wave forms, and vibrato amounts.
