In 1910, The Firebird was put into development for the Ballets Russes. Tcherepnin was hired to write the music, but lost interest. The job was given to Lyadov. Diaghilev grew disappointed with Lyadov. He was slow to get started. The impresario recalled his impression with Stravinsky and  decided the young composer was the man to write the score for The Firebird. Stravinsky was hired.
