| Have you ever imagined yourself conducting while listening to your favorite music? Perhaps you like to play the "air-guitar". Can you imagine an instrument that follows the movements of your hands and converts them into musical sound? Back in the 1920s, a Russian scientist named Lev Termin (who later Americanized his name to Leon Theremin) was working with Radio Frequency (RF) equipment and discovered that he could control noises coming from the equipment by moving his hands nearby. Could he use the same principles to construct a fantastic new musical instrument? The Theremin has left and right antennae that sense the position of the performer's hands. Most commonly, the vertical right antenna (the rod) converts the right hand's position to pitch and the horizontal left antenna (the loop) converts the left hand's position to volume. The rod and loop antennae are reversed on a left-handed Theremin. |
