Leonard Cohen's Hallelujah has been covered countless times, by solo artists, choirs, even instrumentalists. This arrangement is inspired by the rendition by the a cappella group Pentatonix. It features dissonant harmonies that set it apart from most other interpretations. This five-part work can be performed with a large choral ensemble, a group of just five singers, or any chamber group in between, with plenty of opportunity for both solo and group singing.
