Robert Schumann’s “Davidsbündlertänze” is one of the last major works made by New York City Ballet's founding choreographer and balletmaster-in-chief George Balanchine.
 It is set to Robert Schumann's "Davidsbündlertänze" ("Dances of the League of David"), Op. 6 (1837).
 The idea for setting this piano work very likely came from a work created by Robert Joffrey for his own Joffrey Ballet Company, the premier of which took place at the City Center Theater in the late 1970s.
 Joffrey, in turn, received his inspiration from Jonathan Watts, a protege of Joffrey's and director of the Joffrey apprentice company, who, at the suggestion of pianist Neil Stannard (yours truly), created a ballet titled "Evening Dialogues" to this same score.
 This initial version of the Schumann cycle was featured on tour with the Joffrey second company in the mid 1970a.
Romeo and Juliet is ballet created by John Cranko to Sergei Prokofiev's eponymous score for the Stuttgart Ballet in 1962 and first seen in America in 1969.
