Les Sylphides (French: [le silfid]) is a short, non-narrative ballet blanc to piano music by Frédéric Chopin, selected and orchestrated by Alexander Glazunov.

[1] Les Sylphides has no plot but instead consists of several white-clad sylphs dancing in the moonlight with the "poet" or "young man" dressed in white tights and a black tunic.

[5] The long white tutu that Pavlova originally danced in, and that the entire female corps de ballet adopted soon after, was designed by Léon Bakst and inspired by a lithograph of Marie Taglioni dressed as a sylph.

However, its authorized premiere on that continent, by Diaghilev Ballets Russes, was at the Century Theater, New York City, 20 January 1916, with Lydia Lopokova (who also featured in the unauthorized production five years earlier).

Nijinsky danced it with that company at the Metropolitan Opera on 14 April 1916, where it was paired with a similar work to a piano suite (by Robert Schumann), Papillons, also choreographed by Fokine.

A number of musicians have orchestrated the Chopin pieces for major ballet companies, including Maurice Ravel, Benjamin Britten, Alexander Gretchaninov,[6] Roy Douglas, and Gordon Jacob.
