There are set excerpts for a number of the characters and a couple of general ensemble pieces. For each excerpt, below there is a link to the printed music, a piano backing track and a rehearsal track with guide vocals. The piano track (without guide vocals) will be used in the audition so although it's good to practice with guide vocals, you'll need to be comfortable singing without them.
