The theremin is one of the oldest electronic instruments, and the only one known that you play without touching. Moving your hands in the space around its antennas controls pitch and volume. Like the Ethervox, the Etherwave is an authentic adaptation of inventor Leon Theremin's original design. The Etherwave The Etherwave is a quality theremin with a design that retains many characteristics of the original theremins, including a five-octave pitch range and reliable spacing between notes for sophisticated playability. Antennas are nickel-plated 3/8" brass tube and cabinets are furniture-grade hardwood, finished black. The Etherwave is fitted with an adapter for mounting on a standard microphone stand and is designed for use with a musical instrument amplifier such as the Moog TB-15.
