New York City Ballet
The following is the current artistic staff (except dancers, who are listed at List of New York City Ballet dancers):The 66-member NYCB Orchestra is an important symphonic institution in its own right, having played for virtually all of the thousands of performances NYCB has given over the decades. It is one of the most versatile orchestras in the world, on any given week performing perhaps three or four times the repertoire that another symphony might be expected to do. Principal players of the orchestra also perform the majority of the concertos, other solos, and chamber music in the NYCB repertory as well. The orchestra accompanies the ballet on all of its North American tours, and while the ballet uses local orchestras on its international tours, members of the NYCB Orchestra often go along as soloists or extras.
