This success led Diaghilev to hire Stravinsky to write the score for another ballet, "The Rite of Spring". The idea for this ballet was Stravinsky's, and based on a dream he had had about a virgin forced to dance to death to propitiate the god of spring. Stravinsky knew that writing this score would take a long time. He tired of it, and started to work on a concert piece for piano and orchestra to refresh himself. Stravinsky thought of this new piece as a contest between the orchestra and the piano. The orchestra finally overwhelms the piano to emerge the winner.
