In 1875 Vladimir Begitchev asked Tchaikovsky to write a ballet about swans. Begitchev was the official in charge of the repertory of the Imperial Theatres. Tchaikovsky accepted his invitation to write the ballet. He told Rimsky-Korsakov, "I accepted the work, partly because I want the money, but also because I have long had the wish to try my hand at this kind of music." In August he had completed sketches for two acts. He finished the ballet on 10 April 1876.
