What happens between your rehearsals? With cori, singers practice at home and get feedback on intonation and rhythm. So rehearsal starts where the music begins: less note-learning, more musical work.
Come prepared to rehearsal
Practice your part with your choir's practice recordings. Mix the voices in the audio mixer just the way you need them: your part louder, the others quieter. Sing along and see straight away which notes and cues are solid. The lyrics scroll along in sync, and downloaded songs work offline too.
Learning path: ear, rhythm, voice
Short exercises for in between: recognise intervals, tap back rhythms, hit the notes. In small steps, with feedback on every attempt.
For choir directors: less explaining, more music
Create practice recordings directly in the app: sung in part by part, from audio files, or from MIDI and MusicXML. Share practice tips, build setlists for rehearsal and concert, and launch challenges for targeted practice.
Sheet music always with you
Scores and lyrics in one place. Mark breathing marks, dynamics and cues directly on your iPad or iPhone, with Apple Pencil support. Your annotations sync across all your devices, can be shared with the whole choir and exported as a PDF.
Everything around your choir
Rehearsals and concerts in the shared calendar, RSVPs at a glance, automatic reminders and calendar sync. Attendance, announcements and messages with attachments directly in the app instead of chat clutter. The file storage holds files and folders for the whole choir. In rehearsal mode the setlist, sheet music and recordings for the date are ready to go, and the seating chart shows everyone their place in the choir.
Sell concert tickets
One tap turns a performance in your calendar into a finished ticket shop: seating plans for a church or parish hall, ticket categories, concessions and promo codes. Your guests buy without an account, and the money reaches your own bank account daily, already during presale. No subscription and no base fee: you are only charged per ticket sold, payment fees included. The shop itself runs in the browser at tickets.cori.music; the app takes you there in one tap.
Practice that motivates
Streaks, badges and challenges turn practising between rehearsals into a habit, and you celebrate your progress as a choir.
