About this app

BandBook puts your program's entire book on every player's phone. Your director publishes it once; every player carries their own part, their own markings, and a live cue when the call changes on the field.

EVERY PART, EVERY SHOW, ALWAYS ON YOU
The whole book in one place (show music, stands tunes, pep charts, concert season) sorted and searchable, with your part already downloaded. Browse by section, jump by letter, or search by title. Newly added and recently rehearsed charts surface at the top, so nobody shows up to rehearsal with last week's version.

MARK UP YOUR PART, JUST LIKE ON PAPER
Draw, highlight, and add text notes directly on your part. Breath marks, cuts, dynamics, that one lick the staff keeps rewriting; mark it up the way you would with a pencil, except it survives the season. Undo and erase when the arrangement changes again.

THE WHOLE BAND, ON THE SAME CHART
Start a performance and every player's screen follows the set. When the call changes, every device jumps to the right chart at once. No shouted numbers down the line, no flipping pages in a dark stadium. Push alerts for cuts, repeats, and last-second changes to the entire band in one tap.

DRUM MAJORS AND DIRECTORS CALL THE SET
Conductors get a live HUD: what's playing now, what's up next, and what's already been played. Queue the halftime show ahead of time or call stands tunes on the fly, and send an alert to the whole band without leaving the screen.

BUILT FOR THE FIELD
• Parts download to the device; a stadium with no signal doesn't matter
• Tempo and time signature on every chart, with a visual pulse to set off
• Dark mode for night games and pit rehearsals
• Tags to organize the book your own way
• Performance history, so you know exactly what you played and when

INVITE-ONLY, ONE BAND AT A TIME
BandBook is not a public music service. There is no public sign-up and no catalog to browse. Each program uploads its own material to its own private library, visible only to its own members. To join, ask your director or section leader for a join code. For new bands, contact support at support@bandbook.band

BandBook does not supply or distribute sheet music. Each band is responsible for holding the rights it needs for anything it uploads.
