The instrument is based on the principle of induction and the natural capacitance of the human body. Sound is generated by two high-frequency oscillators – one with a fixed frequency, the other variable – and the difference between them. The position of the right hand in respect to the right antenna alters the amount of the capacitance of the variable oscillator and thus determines pitch. The position of the left hand to the left antenna controls volume via changes in voltage.
