For church and community choirs
You make the music, cori handles the admin
The rota, responses, sheet music and practice recordings in one place. You know before every service who will be there, and nobody hunts for the right folder again.
Up and running in minutes. Servers in Germany, GDPR compliant.
A church year is a rhythm
Between the first Sunday of Advent and the end of the church year, a choir easily clocks 60 commitments: rehearsal and service every week, plus the great feasts when everyone wants to be there.
Rehearsals and services
Passiontide and Easter
Pentecost
Summer break
Advent
Christmas
And in between: baptisms, weddings and funerals on a few days' notice. In cori that is one new entry, and everyone knows. The weekly rehearsal simply keeps running as a series.
A church choir plans differently from a project choir
There isn't one concert a year; there is a service every Sunday. The admin often hangs on a single person, and that is exactly what makes it fragile.
The rota lives on paper
Who is singing on Advent Sunday, who at Easter? The rota is pinned up in the parish hall, and nobody has it when they need it.
You only learn the turnout on Sunday
Whether the tenors are covered only shows during the warm-up. So on Thursday you rehearse settings that will not hold on Sunday.
The repertoire repeats, and so does the hunt
Much of it returns every church year, yet somebody still often gathers last year's scores and recordings from scratch.
Services and rehearsals in one calendar
The weekly rehearsal runs as a series, with feasts and occasional offices added individually. Everyone can see what is next without digging through the parish newsletter.
Recurring rehearsals with exceptions for holidays
Services, occasional offices and concerts side by side
Time and place on the entry, including for deputies
Choir rehearsal
Thursday, 7:30 pm
Sunday service
Sunday, 10:00 am
Wedding
Saturday, 2:00 pm
Know before Sunday who will be there
People accept or decline for individual dates. You see the coverage per voice part and can decide in rehearsal whether the four-part setting will hold or whether the three-part version is the safer call.
Responses per service rather than in general

When the repertoire comes round, the music is ready
Scores, recordings and paperwork sit in folders by church season. What you sang last Christmas is ready again the following Advent.
Scores as PDFs, readable right in the app
Recordings live with the piece, not in email
New members are immediately as up to date as everyone else
Advent and Christmas
14 pieces
Passiontide and Easter
11 pieces
Baptisms and weddings
8 pieces
Locus iste
Anton Bruckner
Short-notice changes reach everyone in time
The changed start time, the swapped anthem, the stand-in at the organ: things like that go through the choir chat instead of a phone chain. Anyone who was away simply reads back.
One channel for the whole choir
Messages stay findable
No need to share private phone numbers
Even occasional singers stand secure on Sunday
In every community choir somebody is missing every week for good reasons. With per-voice recordings they catch the setting up at home, hear their own part louder, and still stand secure on Sunday.
Recordings per voice part, your own turned up
Works offline, even with poor signal
No score reading required

W. A. Mozart

From the noticeboard to one place for everything
Most choirs run on a mix of paper, messenger and email. It works as long as the one person who holds it all in their head keeps going.
The rota hangs in the parish hall
Every date in one calendar, with accepts and declines
Apologies arrive by phone, in the chat, or not at all
Coverage per voice part visible before every service
Scores are buried in email attachments and copy folders
Scores live with the piece, offline too
Practice recordings travel by link or USB stick
Per-voice recordings right in the app
Set up within one rehearsal
You do not need anyone who is good with technology.

Practical Answers
Yes, and it almost always goes better than expected. The Happy Voices from Zeiskam, for example, sing with members from their early twenties to well over seventy, and every generation there uses cori. To take part, two moves are enough: accept or decline, and open a score or a recording. Everything beyond that is there to use, but nobody has to. Anyone without a smartphone simply opens cori in the browser on their computer.
Yes, all of them together. The chancel choir, children's choir and brass ensemble are separate choirs with their own music and dates, and anyone singing in several switches in the app with one tap, without signing in again.
Usually the parish: in most congregations the church or the friends' association covers the cost, billed per member. For institutions there is a separate plan that pays off as soon as several choirs sing under one roof.
In Germany. All data is stored on German servers, GDPR compliant, and it belongs to your choir: you can export it in full at any time and delete it again too.
That works, a brief agreement beforehand is all it takes. cori is aimed at mixed choir groups, and use by minors is best cleared with parents and your parish in advance, just as you do for photos or group chats.
No problem! Downloaded sheet music and recordings work fully offline. Responses and messages sync on their own as soon as the phone is back online.
For everything around the choir: yes. Dates, responses and announcements come together in cori and stay findable, instead of sinking between holiday photos. And nobody has to hand out a private phone number for it.
Yes, just as well. Recurring rehearsals, responses, sheet music and recordings work exactly the same for choral societies, city choirs and gospel choirs. Only the examples on this page have a church flavour.
