The Theremin
An oddity here in that it is the
only electronic instrument. The theremin is played by moving your hands (or any
part of your body) in proximity to two aerials. One controls pitch, the other
volume.
The sound is produced in a smooth
continuous tone like a trombone or violin, not in steps like on a piano or
guitar.
They are great for encouraging movement and
particularly useful for activities such as rowing where their physical and
sonic properties both reinforce the nature of the action.
The haunting, ethereal sound is
particularly effective when played through electronic effects such as digital
delay and it can greatly contribute to the atmosphere of a creative session.
