Theremin

The theremin or thereminvox (originally pronounced {{IPA|}} but often anglicized as {{IPA|}} http://www.thereminworld.com/faq.asp) is one of the earliest fully electronic musical instruments. Invented in 1919 by Russian Lev Sergeivitch Termen (also Termin, later gallicized to Léon Theremin), the theremin is unique in that it requires no physical contact in order to produce music and was, in fact, the first musical instrument designed to be played without being touched. The instrument consists of a box with two projecting radio antennas around which the user moves his or her hands to play.
