The Theremin was the first music synthesizer. The Junior Theremin is a smaller version of this classic electronic instrument. Move your hand towards and away from the wire antenna, and the Theremin responds by changing the pitch of the note being played. The device can play both single notes and vary the tone of a single note.

How the Junior Theremin works: The Junior Theremin is a smaller version of this classic electronic instrument. It is played without even touching it. Move your hand towards and away from the wire antenna, and the Theremin responds by changing the pitch of the note being played. The Junior Theremin has two operating modes: continuous and discrete mode. After inserting the battery, the Junior Theremin is in continuous operation. Press both buttons simultaneously to switch between the two operating modes. In discrete mode, as the name suggests, individual or discrete notes are played, not a continuously variable tone. There are eight notes over a single octave. In discrete mode, the pitch of the notes can be changed using both buttons. The left button (-) lowers the pitch, while the right button (+) raises it. You must hold the buttons down to change the pitch. In continuous operation, these buttons do not function.
