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 EtherMusic Festival Moog Music produces the EtherMusic Festival to promote education, performance and networking in the theremin community. The 2008 festival was a rousing success.
