Description: Originally known as the ætherphone / etherphone, thereminophone or termenvox / thereminvox) is an electronic musical instrument controlled without physical contact by the thereminist (performer). It is named after the Westernized name of its Soviet inventor, Léon Theremin (Термéн), who patented the device in 1928. The theremin is controlled by two oscillators. The first antennae is the frequency oscillator, the second antennae controls the amplitude (volume). Due to its sound, the theremin is a staple in movie soundtracks and film scores.
