The Polovtsian Dances (or Polovetsian Dances) (Russian: Половецкие пляски, Polovetskie plyaski from the Russian name of the Turkic Polovtsy people) form an exotic scene in Alexander Borodin's long opera Prince Igor.
The work remained unfinished when the composer died in 1887, although he had worked on it for more than a decade. A performing version was prepared by Nikolai Rimsky-Korsakov and Alexander Glazunov, appearing in 1890. Several other versions, or "completions," of the opera have been made. The dances are performed with chorus and last between 11 and 14 minutes. They occur in Act I or Act II, depending on which version of the opera is being used. Their music is popular and sometimes given in concert. At such performances the choral parts are often omitted. The opera also has a "Polovtsian March," which opens Act III, and an overture at the start. When the dances are given in concert, a suite may be formed: Overture, Polovtsian Dances and March from "Prince Igor."
