The Russian avant garde was far ahead of the West in the development of electronic instruments. Leon Theremin, inventor of the first mass produced electronic instrument, is the best remembered experimenter of this period. The Theremin synthesizes motion and sound the same way the ANS sythesizes images and sound. But his eponymous instrument was hardly Theremin’s only experiment. “Theremin worked on countless projects, striving to bring music, light, movement, smell and touch together in a single technology,” Smirnov and Pchelkina wrote. Scriabin would have been proud.
