Designed and built in 1928 in France by Maurice Martenot, the Ondes Martenot (Martenot Waves) was used by Oliver Messiaen, Darius Milhaud, Edgard Varèse, Pierre Boulez, and other well-known composers.

In its most recognizable form, it was a keyboard instrument with some unusual performance features, among them a finger-ring attached to a ribbon that could be pulled to achieve portamento and other pitch-bending effects, a lever located under the keyboard to control timbral change, and a loudness controller to the left of the keyboard.
