More than any other twentieth-century composer, Stravinsky stands out within ballet modernism. He wrote more scores for dance or for theatre events with a significant dance element (eighteen in total) than any other major composer of his time. It was dance too, primarily Diaghilev’s Ballets Russes, which gave Stravinsky the key platform from which to launch his career, including the opportunity to work with the modernist choreographer George Balanchine (1904–83). Together, Stravinsky and Balanchine formed the most celebrated composer–choreographer collaboration of the century.
