Les Sylphides is a short, non-narrative ballet blanc. Its original choreography was by Michel Fokine, with music by Frédéric Chopin orchestrated by Alexander Glazunov. Glazunov had already set some of the music in 1892 as a purely orchestral suite, under the title Chopiniana, Op. 46. In that form it was introduced to the public in December 1893, conducted by Nikolai Rimsky-Korsakov.
