A sign-up sheet for open mic nights
How the night runs
Open a session in open mic mode and share the code — on a poster, on the screen behind the stage, or read out from the mic. Anyone in the room can join with it, and they do not need an account.
From there the night runs in two lists. The board is what the room wants to hear. The running order is what is actually going to happen. A song moves from one to the other the moment somebody signs up to play it.
The room requests, performers sign up
Anyone can put a song on the board. If somebody has already requested it, a second request is counted as backing rather than a duplicate line — so forty people shouting for the same song is one entry with a big number beside it.
Backing sorts the board, which is how a performer scanning for something to play sees what the room actually wants. It does not buy a better place in line — only signing up to play does that.
First to be ready, first to play
A song takes its place in the running order when it finds its first player, not when somebody wished for it. A request that has sat there since the doors opened does not leapfrog one that found a guitarist an hour later.
It also keeps the night fair to small lineups: a solo acoustic number that finds its one player at 8:05 goes on before a five-piece that assembled at 8:10. Nothing is ordered by how many people are in the band.
If the lineup falls apart, the song steps back
Performers can sign off as well as on. If the last one drops out, the song returns to the board and loses its place — a slot in the running order with nobody to play it is exactly what the board exists to prevent. Sign back up and it rejoins at the back.
Once a song is playing or has been played, that is settled and it stays put.
What the host keeps control of
The host is not a gate on any of this — the room runs itself. But they can reorder the running order when the night needs it, and remove anything that should not be up there.
Put the list on the wall
The audience screen runs in any browser, so a laptop pointed at a TV shows the room who is up next along with the lyrics and the beat for whoever is playing. It needs no login, so it is safe to leave running all night.
Common questions
No. The session runs in a phone browser from the session code, with no account and no install. There is a mobile app if you want one, but the night does not depend on anyone having it.
Yes, but that is a separate mode. Voting mode lets the host open a round and have the room pick the next song from a shortlist. Open mic mode is the one where performers sign up to play.
A song can only be on the board once. A repeat request is counted as backing for the existing entry, and a song already in the running order cannot be requested again.
Yes. The mode can be changed at any time from the Manage sheet, and everyone in the room is told when it changes. The board is kept if you switch away and switch back.
