The terpsitone is a variant of the theremin, and has a metal plate beneath a dance platform that acts as an antenna, thus allowing the vertical movement of the entire body to regulate changes in pitch. A second antenna behind the dancer is used to control volume through horizontal movement. A special mechanism limits the instrument to semitones only.
