The theremin (/ˈθɛrəmɪn/; 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 instrument’s controlling section usually consists of two metal antennas that sense the relative position of the thereminist’s hands and control oscillators for frequency with one hand, and amplitude (volume) with the other. The electric signals from the theremin are amplified and sent to a loudspeaker.
Miles Brown is a student of Russian theremin virtuosa Lydia Kavina, the first cousin twice removed of Léon Theremin.
Miles plays Moog Etherwave Pro and Moog Etherwave theremins. He also uses CV control outputs of these theremins to control other analogue synthesiser voices.
