How to share sheet music with your band

A PDF in a group chat is a copy, and copies drift. Change a key, cut a verse or fix a wrong chord and you now have two versions in circulation with no way to tell which is which. The person who missed the message plays the old one, and nobody finds out until the chorus.

It also puts the music in the wrong place. Sheet music buried in a chat thread is three taps and a scroll away at the exact moment you have a guitar in your hands — and a file that has to be found is a file somebody will stop looking for and just busk.

Upload a Guitar Pro file to a song in Coda and it belongs to the song, not to a message. Everyone in the session opens the same tab on their own phone, and when you change it, it changes for everyone — there is only ever one version, so there is nothing to keep in step.

The file renders as readable notation and tablature in the browser and in the mobile app, which means nobody in the band needs tab software installed to read what you sent. That is usually the part that quietly stops a band sharing anything at all.

Not every player reads tab, and not every song needs it. Chord charts and timed lyrics are shared the same way and from the same song, so the guitarist can be on the tab, the keys player on the chart and the singer on the words — all of them on the same song at the same moment.

Timed lyrics scroll themselves as the song plays, holding the current line a quarter of the way down the screen so you can see what is coming rather than what has just gone. Scroll it yourself and it stops following; a few seconds later it catches back up to wherever the band has got to, instead of making you find your place again.

Whoever is hosting picks the song, and every screen in the room follows to it. There is no “what are we doing next” and no page two people are on different sides of.

The tempo is shared too. Every device runs off one clock, kept within about ten milliseconds across the room, so the count-in, the metronome and the beat agree everywhere rather than drifting phone by phone.

Anyone can join a session with the session code and nothing else — no account, no install, no invitation to accept. That matters more than it sounds: the function of most sharing tools is lost the moment one person in the room is not signed up, and a dep who turns up an hour before the gig will not be making an account.

An account is only needed to host a session or to keep setlists between rehearsals.

Point a laptop at a TV or a projector and open the audience screen. It shows the current song, the lyrics and the beat to the whole room at once — useful at a gig, and just as useful in a rehearsal space where nobody wants to be looking down at a phone.

It needs no account and no app, so the venue’s own machine in the corner will do.

Sometimes there is nothing to share because nobody has written it down. Coda has a tab editor that runs in the browser, so the arrangement your band actually plays — the one that is nowhere on the internet — can be written out once and then shared like anything else.
