More music in every rehearsal, less note-bashing

One evening a week has to carry it all

Two hours a week have to fit warming up, note-bashing, musical work and the organisation around it. Usually the music gets what is left.

Note-bashing eats the evening

You play a line, one section repeats it, three sections wait. And what almost sat on Tuesday has faded by the following week.

You plan the evening blind

Whether you can work on the hard piece depends on who turns up. You find out at half past seven, when the plan is already made.

Practice at home is a black box

Maybe you even hand out recordings, and then you hope. Who opens them, and where people struggle, you only hear when it goes wrong in rehearsal.

Voice-part recordings in minutes, not weekends

Record each part directly in cori, or import what you already have: MIDI files or a multitrack recording. Published once, every singer finds their own part, with the other voices underneath.

  • Record in the app, no studio or editing software

  • MIDI import and multitrack recordings work just as well

  • Singers pick their voice and the passage to practice

Mark it once, it's in everyone's score

You draw a breath mark, a dynamic or a cut into the score, and the change appears on your choir's devices right away. You decide who sees it: only you, one voice section or everyone. No more "please write this in", and no more that one copy where it's missing after all.

  • Draw breath marks, dynamics and cuts straight into the score

  • Changes appear live on every device

  • Visible only to you, to one voice section or to the whole choir

Practice at home with feedback, not just playback

Your singers sing along with their part and get feedback on pitch and rhythm. Hard passages loop at reduced speed until they sit, and everything works offline too. And the learning path builds the fundamentals on the side: short ear and rhythm exercises that adapt to each singer's level.

  • Feedback on pitch and rhythm after every run

  • Loop a passage, slow it down, bring it back up to tempo

  • No score-reading required

  • A learning path trains ear and rhythm on the side

A weekly challenge keeps the whole choir practicing

Set a challenge in seconds: one passage five times, one exercise from the learning path ten times. The choir sees its shared progress, streaks reward the routine, and you see where the choir stands without chasing anyone.

  • Challenges tied to real pieces and passages

  • Streaks and a choir board for gentle competition

  • Practice stats for every challenge

See the lineup before you plan the evening

Everyone accepts or declines per date, and you can see days ahead how each voice part is covered. Rehearse what will work, and move what won't hold.

  • Coverage per voice part, days in advance

  • Responses for rehearsals, concerts and sectionals

  • Attendance across the season, not single snapshots

Program, seating plan and choir chat in one place

The setlist hangs on the rehearsal date, scores and recordings live with the piece. In the choir chat you link a piece directly, and one tap starts the recording. Questions like "Who is singing at the Christmas market?" get settled with a poll instead of forty replies.

  • Setlists attached to rehearsals and concerts

  • Link pieces in the chat: one tap and they play

  • Polls with a deadline and a view of who has voted

Sell the concert tickets while you're at it

cori Tickets turns the concert in your cori calendar into a ticket shop, with a seating plan, concessions, discount codes and PDF tickets. The audience buys without an account, and the money goes straight to your choir's account.

  • Numbered seats or open seating

  • Entry via phone scanner, even offline

  • 5% + €0.50 per ticket, no subscription, no setup fees

Set up within one rehearsal

No IT project, no training session. Most directors are done before the warm-up.

  1. 1
    Create the choir

    Name and voice parts, two minutes. One invitation link goes to your mailing list and people join themselves.

  2. 2
    Add your repertoire

    Upload scores, import MIDI files or record the voice parts for the next concert.

  3. 3
    Set the first goal

    Enter the next rehearsal and a small weekly challenge. Practice starts now, not at the next rehearsal evening.

Practical Answers

Minutes per part, not hours. You record each voice once in the app, and if you already have MIDI files or finished recordings, you simply import them: cori turns them into practice material for every section.

No, your phone is plenty. Your singers need to hear their part clearly, not a studio production. And if you have professional recordings, you can of course use those just as well.

Yes, and usually more than you would expect. To take part, two moves are enough: accept or decline, and open your own part to practise. Everything beyond that is there to use, but nobody has to. Anyone without a smartphone opens cori in the browser. And a small weekly challenge gets more people practising than any appeal from the podium.

Yes, as many as you like. You switch between your choirs in the app with one tap, without signing in again, and each choir has its own repertoire, members and calendar.

You pay per member: small choirs pay less, large ones more, and there is a separate plan for schools and institutions. The best way to find out is to simply try it: 30 days free with the full feature set, no credit card needed.
