Geophone (percussion instrument)

From Wikipedia, the free encyclopedia

This article is about the percussion instrument. For the electronic seismic recorder, see Geophone.

The geophone is a percussion instrument, invented by the French composer Olivier Messiaen for use in his piece for piano and orchestra Des canyons aux étoiles… ("From the canyons to the stars…"). It consists of a drum filled with thousands of small lead pellets, and is played by swirling it around slowly so that the noise of the pellets resembles the sound of dry shifting earth.

Messiaen commissioned a Parisian instrument maker to construct one to his design, and he carried this instrument worldwide to early performances of the piece (which was given its first performance in New York). Messiaen's wife, Yvonne Loriod, commented that when she and the composer first collected the new instrument from the maker in her car it made a "splendid crescendo" whenever they went round a corner.

Other notable works that use the geophone include Asyla by Thomas Adès and ...towards a Pure Land by Jonathan Harvey (composer).
