Pentatonix: Sing: Upper Voices a Cappella: Vocal Score

This original song from a cappella supergroup Pentatonix is masterfully arranged by Wayne Grimmer, keeping all the fun and pop sensibilities of the original, and making it accessible for male, female, or mixed quartet or chorus in 4-part harmony. A great opener or high-energy point of any show, this chart is a fantastic addition to any music library.
