The Rite of Spring ("Le Sacre du Printemps") is a ballet in two parts. The entire ballet was a concept developed by Igor Stravinsky. He wrote the music. The set and costumes were designed by Nicholas Roerich. The dances, which Stravinsky hated, were choreographed by Vaslav Nijinsky. Stravinsky complained that Nijinsky had no understanding of the rudiments of music.
