Create "handsfree" weird and wonderful music!

The original Theremin was produced in the 1920s by Leon Theremin, and the basic idea has been periodically reborn since then. The Theremin is probably more popular now than at any time in the past, and still manages to keep some of its mystique in this technological age when just about anything seems possible.

A Theremin is an electronic musical instrument that is played without any physical contact being made with the instrument. The pitch is controlled by moving one hand closer to an “aerial” or sensor plate to produce an increase, or moving it further away to provide a reduction in pitch.

A similar method is used to vary the volume. Moving the other hand closer to a second aerial gives an increase in volume, and moving it further away produces a reduction in volume.
