Random Zelda Theme

The theremin is an early electronic musical instrument controlled without contact from the player. It is named after its Russian inventor, Professor Leon Theremin, who patented the device in 1928. It was originally known as the 'termenvox' or 'aetherphone', the former of which was subsequently anglicised to 'theremin.' The controlling section usually consists of two metal antennas which sense the position of the player's hands and control radio frequency oscillators for frequency with one hand, and volume with the other. The electric signals from the theremin are amplified and sent to a loudspeaker.
