@TheHeartnet11 The instrument is a theremin, the world's oldest electronic musical instrument, unique in that it is played without physical contact. Essentially, a theremin uses two extremely sensitive antennae -- one for pitch, the other for volume -- to sense the position of the musician's hands in space. Sound is generated electronically based on the hands' positions.
