The Ondes Martenot is an electronic musical instrument invented in 1928 by Maurice Martenot in France. It produces eerie, ethereal sounds using a keyboard and a sliding ring. Its unique, haunting tones have been featured in film scores and classical compositions. The instrument is similar to the theremin but offers greater control and expression.
