Fête des belles eaux, for 6 ondes martenot, II/14

Fête des belles eaux (French: Festival of the beautiful waters) is a 1936 suite of incidental music by French composer Olivier Messiaen. The suite, commissioned for the 1937 Paris Exposition, has eight movements, and was scored for six ondes Martenots. It was written to accompany the movements of the fountains and fireworks at the exposition.

The work remained unpublished until 2003, ten years after Messiaen's death, when it was issued by Éditions Alphonse Leduc.
