Your own arrangements

Write the arrangement your choir sings in the creator: sing the tune, get the other parts suggested, and change any note. Share it with your group like any of our songs.

Teachers and younger singers. Choir groups are for singers 18 and over for now, so they suit adult and community choirs. Singers from 13 can still learn any part on their own, and send you a link or a practice track.
