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. The Etherwave is an authentic adaptation of inventor Lev Termen's original design. The Etherwave is a quality musical instrument designed for ruggedness and portability. It has 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 with a custom Moog stain. The Etherwave is fitted with an adapter for mounting on a standard microphone stand and works best with Moog's TB-15 instrument amplifier. All Etherwaves ship with two video tutorials on one DVD: Clara Rockmore: the Greatest Theremin Virtuosa and Mastering the Theremin, featuring Lydia Kavin
