. A forerunner of the synthesizer, it consists of a wooden box fitted with two radio-frequency oscillators and two metal antennas, a vertical rod on the instrument's right and a horizontal ring on its left. The player moves the hands in the air around the antennas without touching them, creating changes the antennas' electromagnetic fields. The right hand controls the pitch, the left hand, the volume. The sine-wave tones that are produced are then amplified and fed into a loudspeaker.

The theremin's sound has been described as like that of a violin but more spooky and otherworldly. While some classical composers have written for the instrument, e.g., Henry CowellCowell, Henry Dixon

Theremin

 

(etherophone), an electrophonic musical instrument, invented in 1921 by the Soviet engineer L. S. Termen. In order to produce a musical tone, the theremin makes use of audio-frequency electrical oscillations produced by a vacuum-tube generator; the oscillations are amplified and then converted into sound by a loudspeaker. An upright, metal rod attached to a metal arc is used to change the frequency and amplitude of the oscillations generated (the pitch and loudness of the sound); the rod and arc serve as the generator’s oscillatory system. The performer controls the theremin by changing the position of the palms of his hands: the hand near the rod controls the pitch, and the hand near the arc controls loudness. The theremin can be made to sound like a violin, cello, flute, or other musical instrument; the timbre of the sound is determined by the operating mode of the generator.
