Ballet in one act with choreography by Robbins, music by Chopin, costumes by J. Eula, and lighting by T. Skelton. Premiered 22 May 1969 (gala benefit preview, 8 May) by New York City Ballet at the State Theater, New York, with McBride, Villella, A. Kent, Leland, Mazzo, Verdy, A Blum, J. Clifford, Maiorano, and Prinz. It was first conceived as a pas de deux for McBride and Villella but grew as Robbins enlarged his chosen music to include a selection of études, waltzes, mazurkas, a nocturne, and a scherzo. In its final form, five couples dance in response to the music and to the changes in landscape and mood evoked by the lighting. It was dedicated to Jean Rosenthal (who died 1 May 1969) and has been revived for Royal Ballet (1970) and Paris Opera Ballet (1991), both in stagings by Robbins himself, also by San Francisco Ballet in 2002.
