Play the air.
Right hand steers pitch across the field. Left hand rides the volume — lift to swell, drop to hush. No camera? The instrument follows your mouse, finger, or the music keyboard row instead.

What is a theremin?
The theremin is the first instrument played without touching it. Two antennas<br>sense where your hands are: the vertical one sets pitch , the horizontal loop sets<br>volume . Two radio oscillators beat against each other and the difference between<br>them is the note you hear — heterodyning.
Leon Theremin<br>(Lev Termen) built it in Russia around 1920 and called it the termenvox — "Theremin's voice".<br>Clara Rockmore<br>turned it into a concert instrument. Here your webcam replaces the antennas: by default the<br>right hand takes pitch and the left rides volume, swappable under Gesture .
