How does it work? The main interface of the ondes martenot was originally a metal ring, worn on the player's right index finger that, when slid up and down a wire, would create theremin-like sweeps in tone (through oscillations in vacuum tubes).

How is the ondes martenot played?

The ondes Martenot can be played with a metal ring worn on the right index finger. Sliding the ring along a wire produces "theremin-like" tones, generated by oscillations in vacuum tubes, or transistors in the seventh model.

How does a theremin work?

How does a theremin work? A theremin stands in front of an instrument and moves their hands along with the two antennas. The distance from an antenna determines its frequency and pitch while the distance from the other determines the amplitude. The sound is then amplified and sent through a speaker.
