Published by Andrew Smith (A0.1455658). Jacob Collier's World O World is a powerful choral work that challenges the musicians to embrace many different consonant and dissonant harmonies throughout the piece. This concert band arrangement is meant to be performed chorale or hymn-like. The length of pauses and cut-offs at the breath marks can be modified by conductor, but they should be similar to the original recording's phrasing. No percussion parts are included due to the a cappella style of the original.
