cori – The App for Choirs

cori Tech

About this app

cori – the choir app for better rehearsals, confident singing and great performances.

Try cori free for 30 days with your entire choir.

What happens between your rehearsals? With cori, singers practice their part at home and even get feedback on intonation and rhythm. So your choir rehearsal starts where the music begins: less note-learning, more musical work.

🎵 Come prepared to choir rehearsal
Practice your choir part with personalized recordings from your choir director. Mix the voices in the audio mixer just the way you need them: your part louder, the others quieter. Sing along and get direct feedback on intonation and rhythm. Lyrics, cues and notes stick faster – and you sing with more confidence.

🎼 For choir directors: less explaining, more music
Create practice recordings directly in the app – even from MIDI files, no extra tools needed. Share practice tips, create setlists for rehearsals and concert day, and launch challenges for targeted practice. Your choir comes prepared to rehearsal and you have more time for expression, dynamics and choral sound.

🎶 Sheet music always with you
All scores and lyrics in one place. Mark breathing marks, dynamics or cues directly on your tablet or smartphone – with stylus support. Your annotations sync automatically across all your devices.

🗓️ Everything around your choir
Rehearsals and concerts in the shared choir calendar. RSVPs and absences at a glance. Automatic reminders and calendar sync. Announcements directly in the app – instead of endless chat clutter.

🏆 Practice that motivates
Practice streaks and challenges make practicing between rehearsals fun. Get more confident, sound better – and celebrate your progress as a choir.
