Ondes Martenot

The ondes Martenot is played with a keyboard or by moving a ring along a wire, creating "wavering" sounds similar to a theremin. It was invented in 1928 by the French cellist Maurice Martenot, who was inspired by the accidental overlaps of tones between military radio oscillators, and wanted to create an instrument with the expressiveness of the cello.

The French composer Olivier Messiaen used the ondes Martenot in pieces such as his 1949 symphony Turangalîla-Symphonie, and his sister-in-law Jeanne Loriod was a celebrated player. It appears in numerous film and television soundtracks, particularly science fiction and horror films. Contemporary users of the ondes Martenot include Tom Waits, Daft Punk and the Radiohead guitarist Jonny Greenwood.
