Symphonic Dances, Op. 45, is an orchestral suite in three movements completed in October 1940 by Russian composer Sergei Rachmaninoff. It is his final major composition, and his only piece written in its entirety while living in the United States. The work allowed him to indulge in a nostalgia for the Russia he had known, much as he had done in the Symphony No. 3, as well as to effectively sum up his lifelong fascination with ecclesiastical chants. In the first dance, he quotes the opening theme of his Symphony No. 1, itself derived from motifs characteristic of Russian church music. In the finale he quotes both the Dies Irae and the chant "Blessed art thou, Lord" (Blagosloven yesi, Gospodi) from his All-Night Vigil. Background Rachmaninoff composed the Symphonic Dances four years after his Third Symphony, mostly at the Honeyman estate, "Orchard Point", in Centerport, New York, overlooking Long Island Sound. Its original name was Fantastic Dances, with movement titles of "Noon", "Twilight", and "Midnight". While the composer had written to conductor Eugene Ormandy in late August 1940 that the piece was finished and needed only to be orchestrated, the manuscript for the full score bears completion dates of September and October 1940. It was premiered by Ormandy and the Philadelphia Orchestra, to whom it is dedicated, on January 3, 1941. The work is fully representative of the composer's later style with its curious, shifting harmonies, the almost Prokofiev-like grotesquerie of the outer movements and the focus on individual instrumental tone colors throughout (highlighted by his use of an alto saxophone in the opening dance). The opening three-note motif, introduced quietly but soon reinforced by heavily staccato chords and responsible for much of the movement's rhythmic vitality, is reminiscent of the Queen of Shemakha's theme in Rimsky-Korsakov's opera The Golden Cockerel, the only music by another composer that he had taken out of Russia with him in 1917. The Symphonic Dances combine energetic rhythmic sections, reminiscent of Stravinsky's The Rite of Spring, with some of the composer's lushest harmonies. The rhythmic vivacity, a characteristic of Rachmaninoff's late style, may have been further heightened here for two reasons. First, he had been encouraged by the success of his Rhapsody on a Theme of Paganini as a ballet in 1939 and wanted to write something with which to follow it up. Second, he may have included material intended for a ballet titled
