Apollo (ballet) festival of contemporary music to be held the following year at the Library of Congress in Washington, D.C. The story centres on Apollo, the Greek god of music, who is visited by three Muses: Terpsichore, muse of dance and song; Polyhymnia, muse of mime; and Calliope, muse of poetry. The ballet takes Classical antiquity as its subject, though its plot suggests a contemporary situation. It is concerned with the reinvention of tradition, since its inspiration is Baroque, Classical, or even post-baroque/rococo/galant. It is scored for chamber orchestra of 34 string instruments (8.8.6.8.4). Stravinsky began composing "Apollo" on 16 July 1927
