Choir at rehearsal

In short

Gumb is a choir app for rehearsals and concerts. Choir directors set up the weekly rehearsal as a recurring event and concerts, rehearsal weekends and small performances with their own event type, and singers respond by the response deadline. Because every voice part is its own group, you see before the concert whether soprano, alto, tenor and bass are covered. Sheet music and lyrics sit right on the event or in the voice part's folder, and with a poll event the choir votes, for example on the song for a performance.

From chat chaos to a full choir

What costs choir directors time between two rehearsals, and how Gumb fixes it.

Without Gumb: Whether enough tenors turn up for the concert, you only learn at the dress rehearsal.

With Gumb: Every voice part is its own group. You see responses per voice and can react early.

Without Gumb: Sheet music gets copied, handed out and lost anyway.

With Gumb: Sheet music and lyrics sit on the event or in the voice part's folder, up to 50 MB per file.

Without Gumb: Which song to sing at the performance is debated in the chat without a result.

With Gumb: A poll event with your own answers shows right away what the choir votes for.

Without Gumb: Who helps at the till or the bar at the concert stays open until the last minute.

With Gumb: Helper shifts become tasks on the concert. Members sign up themselves.

With all my hobbies I always had a big muddle. With the Gumb app I can see who is coming when, and I can also ask why not... The layout is very user-friendly and modern. I think the app is very good and recommend it.

FAQ: the choir app

Can I see whether every voice is covered for the concert?

Yes. Create a separate group for every voice part. On the event you see responses live, in total and per group, so per voice.

How do I share sheet music with the choir?

Sheet music for a specific concert goes right on the event. Practice material for one voice belongs in the voice part's folder, which only that group sees. Files can be up to 50 MB each. Owners, admins and group leaders upload them.

Can the choir vote on a song or a date?

Yes, with an event type called “Poll”. The answer options stand for the choices, for example one song per answer. In the scheduler you see right away how people voted.

How do I organize helpers for the annual concert?

Create tasks such as till, bar or cloakroom and turn them on for the concert. Members sign up themselves, or admins assign them. Everyone sees who takes on what.

Can I analyze rehearsals, concerts and performances separately?

Yes. With your own event types you filter the attendance report by event type, period and voice part and export it as an Excel file.

How do parents cancel for their child in the children's choir?

Every child has their own account with their own email address. Parents log in with the same credentials and cancel for the rehearsal. Admins can create children's accounts upfront.

Can one director lead several choirs?

Yes. A member can belong to several groups and sees the rehearsals of every choir bundled in one place.
