Know your part before rehearsal

Your part, alone or in the mix

Listen to your part, sing along with it, then sing it on your own while the other parts carry on around you. Stuck on a phrase? Loop it, or slow it down.

When your director uses Stackapella

In a choir group, your director shares the songs and tells you your part. You join free, and the group's songs are open to you while you're in it. Your director sees only whether you've started or recorded your part. Choir groups are for singers 18 and over.

Practice tracks

Export a track of everything but your part, to sing along with, or of your part louder, the way choirs use them. Both are free.
