The most famous music composed for Ballets Russes was that by the composer Igor Stravinsky. His ballets include "The Firebird", "Petrouchka", "The Rite of Spring", "Les Noces" and "Apollon musagète". The first time that "The Rite of Spring" was performed many in the audience hated it and booed and started to fight. Others thought it was brilliant. Stravinsky's music was original and shocking, and Nijinsky's choreography went beyond classical ballet technique. The audience found it difficult to understand the music and dance. They were used to the romantic music and classical ballet of the nineteenth century.
