The Ondes Martenot, a monophonic electronic instrument invented in 1928 by Maurice Martenot, has been used by composers including Honegger, Schmitt, Ibert and, perhaps most famously, Messiaen. Honneger even thought it might replace the contrabassoon in an orchestra. The Swiss composer remarked, ‘The instrument has power, a speed of utterance, which is not to be compared with those gloomy stove-pipes looming up in orchestras.’ Here's a brief guide to this atmospheric and rather specialo instrument.
undefinedWhat is the Ondes Martenot?
The Ondes Martenot is made up of two units. The main section is made up of a keyboard and pull-wire operated by a ribbon controller for the index finger. The keys are capable of slightly shifting, which has the effect of moving the pitch. Sliding the ribbon with the index finger creates glissando sweeps and expressive portamentos.
The left-hand uses the other unit of the instrument, which has controls accessed from a pull-out drawer. These are able to adapt and modify the articulation, dynamics and tone produced.
The instrument's modern-day fans
Modern-day fans of the instrument include Radiohead's Jonny Greenwood, who often tours with an Ondes Martenot. French pop duo Daft Punk have also used the instrument in many of their tracks.
Its mysterious sound has been compared to the human voice. In some instances it can sound like a soothing string quartet; in others it is eerie and ominous.
What works use the Ondes Martenot?
The most famous work to feature the Ondes Martenot is undoubtedly Messiaen's Turangalîla Symphony. You'll be able to hear a performance of the Turangalîla, featuring Cynthia Millar playing the instrument, at the 2024 BBC Proms.
