Choir management software
Choir management that gives you the rehearsal back
Rehearsal dates, attendance, sheet music, recordings and announcements in one place. Singers see exactly what they need, and nothing is maintained twice.
Up and running in minutes. Servers in Germany, GDPR compliant.

The work is rarely the singing
Between rehearsals a choir runs on spreadsheets, group chats and mail threads that know nothing about each other. That patchwork is where the evenings go.
Attendance in a spreadsheet
Who is coming to the dress rehearsal? The answer is in three chat threads and a list someone types up afterwards.
Sheet music in an email attachment
Only the people who found the right email have the current version. New members start from nothing.
Recordings passed around by hand
Last Tuesday's sectional is on somebody's phone and never reaches the people who need it.
Six tools become one
The jobs stay the same. They just stop living in six places that someone has to reconcile by hand.

A repertoire that carries everything
Every song in cori carries what the choir needs for it: sheet music, practice recordings per voice and the choreography. Open a piece and you get the current state, not the version from an old email.
Multitrack audio editor: record and cut practice tracks right in the app
Choreography videos per voice for moves and performances
Sheet music annotations that sync to a voice part or the whole choir

Rehearsal planning that keeps itself up to date
Set the weekly rehearsal up once, including the exceptions and the extra calls. Everyone sees the next date with time and place, and a change reaches the whole choir straight away.
Recurring dates with one-off exceptions
Concerts, extra rehearsals and socials in the same calendar
The setlist attached to the date, so nobody wonders what you are rehearsing
Tuesday rehearsal
19:30 · Community hall
Sectional: tenors & basses
18:45 · Room 2
Summer concert
17:00 · Town hall
Attendance without chasing anyone
People accept or decline in the app, with a reason if they want to give one. You can see how each voice part is covered and plan the rehearsal around it.
Responses per date and per voice part
A picture of the whole season, not one evening at a time
Export for your committee and funding applications

Shared files everyone can actually find
The repertoire already carries the music and recordings; the shared files cover everything else: folders for the paperwork, open to the whole choir.
Bylaws, minutes and concert plans in one place
Share any file straight into the choir chat
Anyone who joins is immediately as up to date as everybody else

Announcements that land
What matters goes in the choir chat instead of a group that also carries holiday photos. Anyone who missed a rehearsal can read back what was decided.
One channel for the whole choir
Messages stay findable instead of scrolling away
No need to share private phone numbers
Push notifications so nothing slips through
Anna
Choir director
Thursday's rehearsal moves to the parish hall. We start with the Kyrie, bring the Mozart.
Thanks! See you Thursday.
Practice happens between rehearsals
You can set practice goals, say a passage five times a week. The choir sees the shared progress, and you see where it is still not landing.
Weekly goals for individual pieces
Progress visible to the whole choir
Per-voice practice recordings right next to them

Everything a choir season needs
Beyond the big five, cori covers the long tail of choir life, so nothing extra has to be bolted on later.
Members and roles
Voice parts, contact details and manager rights in one register that stays current.
Setlists and repertoire
Build the programme per concert and rehearse from the same list everyone sees.
Voice-part recordings
Practice tracks for every voice, with a balance each singer controls.
Sheet music in the app
PDFs open right in cori, in the rehearsal room and on stage.
Streaks and challenges
Small nudges that keep practice going between rehearsals.
Concert tickets
Sell tickets for your concerts with cori Tickets, from the same account.
Several choirs, one login
Switch between ensembles and projects without signing out.
Works offline
Music and downloads stay available when the rehearsal room has no signal.
GDPR by default
Servers in Germany, full export, and your members' data stays yours.
And much more.

One app, three jobs
Directors, committees and singers look at the same choir and each see the part that is theirs.
For choir directors
Plan the music, not the logistics: who is coming, what is on, and where practice stands.
Voice-part coverage before every rehearsal
The setlist attached to every date
Practice progress per piece
For committees and treasurers
The paperwork side: a clean register, attendance records and pricing that scales with the choir.
A member list that keeps itself current
Attendance export for grants and annual meetings
Fair per-member pricing
For singers
One place to look and practice: the next date, the right music and the recording for your part. Singers who practice with cori come to rehearsal prepared, and whoever misses one catches up on the music at home.
Accept or decline in two taps
Your part's recordings, also offline
Streaks that make practice a habit
The switch
What changes in the first month
Less admin
Replies, lists, and sheet music mostly take care of themselves.
More music
Real practice happens between rehearsals, and you can hear it.
Without cori
Chasing replies across three chats before every concert
Resending the same PDF because nobody can find the mail
Typing up the attendance list again after the rehearsal
Answering “when is it again?” a dozen times a week
Miss a rehearsal and you fall behind
With cori
Replies arrive by themselves, sorted by voice part
One music library that is current for everyone
Attendance records itself as people respond
The calendar answers before anyone has to ask
Whoever misses a rehearsal catches up at home
Set up within one rehearsal
There is no project plan. Most choirs are done before the warm-up.
1
Create the choir
Name, voice parts, done. It takes two minutes.
2
Invite the members
One link goes to your mailing list. People join themselves, so you never add anyone by hand.
3
Add the first date
Put the next rehearsal in, attach the setlist, and from there the calendar largely maintains itself.
Jawaban Praktis
Jujur saja: satu kali latihan sudah cukup. Buat paduan suara, kirim tautan undangan, masukkan jadwal pertama, selesai. Partitur dan rekaman bisa ditambahkan pelan-pelan, tidak ada yang harus siap di malam pertama.
Hampir selalu berjalan lebih baik dari yang dikira. Happy Voices dari Zeiskam, misalnya, memakai cori dengan anggota dari usia dua puluhan awal sampai di atas tujuh puluh, lintas semua generasi. Untuk ikut serta memang cukup dua gerakan: konfirmasi hadir atau tidak, dan membuka partitur atau rekaman. Fitur lainnya boleh dipakai siapa saja, tapi tidak ada yang wajib. Dan siapa pun yang tidak mau memasang aplikasi bisa memakai cori langsung di browser.
Ya, sebanyak yang kalian mau. Kalian berpindah antar paduan suara di aplikasi dengan satu ketukan, tanpa masuk lagi. Paduan suara proyek untuk satu konser berjalan sama persis dengan paduan suara yang sudah bertahun-tahun latihan tiap Selasa.
Di Jerman. Semua data tersimpan di server Jerman sesuai GDPR dan menjadi milik paduan suara kalian: kalian bisa mengekspornya secara lengkap kapan saja dan juga menghapusnya.
Kalian membayar per anggota: paduan suara kecil membayar lebih sedikit, yang besar lebih banyak, dan sekolah serta institusi punya tarif sendiri. Cara terbaik adalah langsung mencoba: 30 hari gratis dengan semua fitur, tanpa kartu kredit.
Ya! Partitur dan rekaman yang sudah diunduh tetap tersedia offline, termasuk di aula tanpa wifi. Jawaban dan pesan tersinkron sendiri begitu ponsel kembali mendapat sinyal.
Santai saja, tanpa tanggal batas: kalian mulai berdampingan dengan yang sudah ada. Buat paduan suara, kirim tautan undangan, masukkan jadwal-jadwal berikutnya. Anggota mengisi data mereka sendiri saat bergabung, jadi tidak ada yang perlu dipindahkan manual. Kebanyakan paduan suara berjalan ganda selama satu dua minggu, lalu spreadsheet lama tertidur dengan sendirinya.
Untuk itu ada peran, dan kalian bisa mengubahnya kapan saja. Pengelola merencanakan jadwal, mengurus partitur dan berkas, serta melihat kehadiran seluruh paduan suara. Penyanyi melihat jadwal, partitur, dan rekaman mereka sendiri dan menjawab untuk diri sendiri. Hak pengelolaan bisa diberikan kepada sebanyak mungkin orang, supaya tidak ada yang bergantung pada satu orang saja.
