Relax. Revive. Repeat.
Invented in 1927, Leon Theremin’s eponymous Theremin was a device far ahead of its time. The the- remin was the first ever electronic musical instrument, and (until very recently) the only one played without physical contact with its performer. It uses the capacitance between the performer’s hands and two antenna-like metal rods attached to opposite sides of the device to determine the pitch and ampli- tude of the sound it creates. Thus, by moving their right hand close to the pitch antenna and their left hand far away from the amplitude antenna, a performer would produce a loud high-pitched tone. Be- cause it responds to extremely subtle changes in hand position, the theremin can be an extremely re- sponsive and expressive musical device. More importantly, it set off a hundred years of musical and technological development.
