Polyphony is a group dance choreographed by Peter Kyle in 2008. The work in three sections features Chopin's Nocturne in B Major, Op. 9, No. 3; a rhythmic score by Kyle; and a choral polyphony, O Magnum Mysterium by Morten Lauridsen. The piece was originally created for and performed by dancers at Marymount Manhattan College in New York City.
