About this app

Sing your part.

Partbook is where your choir's practice tracks live. Your leader uploads a
recording per voice; Partbook renders the mixes, times the lyrics, and puts
the result in your pocket.

HEAR YOUR PART UP FRONT
One voice per part. Pull yours forward, or listen from inside the altos for a
while. Every part has its own ready-made mix, and the map is there when you
want to build your own.

LOOP THE CHORUS UNTIL IT STICKS
Lyrics follow the recording line by line. Tap a section to jump, loop the
chorus, stay on the hard bar as long as it takes.

ONE SHELF
New tracks appear for everyone at once, in order, with the notes that belong
to them. Voice notes from your leader sit under the song they explain.

PLAYED ONCE, DOWNLOADED
The songs travel with you. Rehearse on the train, in the car, in the summer
house with no signal.

THE SCORE FOLLOWS THE SONG
Add a MusicXML score and it follows the recording, bar by bar — your part
alone, or every voice on one ribbon. Early access.

Partbook is invite-only: you join through a link from your choir. Lead a
