The Theremin is a musical instrument controlled entirely without physical contact. One of the most intriguing inventions, it “revolutionised music as the predecessor of the modern synthesiser, among others. When radio waves were still a new phenomenon in technology, a young scientist was experimenting with it in his laboratory at the Physical Technical Institute in Saint Petersburg — then called Petrograd — when he noted that the apparatus made strange sounds when he moved his hands around it. Lev Sergeyevich Termen [d.1993] — who later became famous by the name Léon Theremin — was also a classical musician, trained in the cello, and the strange observations piqued his interest. He “played” with the sounds for a while and concluded that he had created a new musical equipment, one that was played without touching” (Nath). It was the world’s first electronic instrument that came to be known as the Theremin.
