Choreography by Balanchine. Tchaikovsky Pas de Deux

An eight-minute display of ballet bravura and technique, Tschaikovsky Pas de Deux uses music that the composer belatedly created for Act III of Swan Lake. It was hurriedly composed for Anna Sobeshchanskaya, a Bolshoi prima ballerina who was scheduled to make her debut in the title role at the fourth performance of the 1877 Moscow production, and sought to enrich the part of Odile. Because the music was not in the original score, it was not published with the rest of Swan Lake, and disappeared for more than half a century. When it was discovered in the Bolshoi Theater archives in 1953, Balanchine sought — and was granted — permission to use it for his own choreography.
