Solange Knowles composing music for New York City Ballet

Solange Knowles is composing an original piece for the New York City Ballet, the singer announced on Tuesday. She said the piece will accompany choreography by Gianna Reisen — who, at 18 years old, became the youngest person ever to choreograph for the ballet in 2017, according to Playbill.

The composition will debut at the ballet's annual Fall Fashion Gala on Sept. 28 at Lincoln Center. The event will be chaired by Laverne Cox and Andy Cohen, among others, and will honor actress Sarah Jessica Parker, who serves as the ballet's vice chair. 

The piece will also be performed at four shows in October and five in May.
