Testimonials

The cori app is a wonderful help and enrichment for every singer in the choir to learn their own voice in a targeted and correct way. Especially helpful - among many other features - I find the ability to adjust the volume of other voices as desired. That way, you're practically already practicing at home with the whole choir! 😍💕

I'm really happy with cori, I use the app regularly to practice concert songs. A cool feature is e.g. the high score for practice days, because it gives you extra motivation to practice. As part of the organization team, it's also helpful to see how many members are coming to certain events.

Totally cool! There are so many things the app can do! The calendar, the challenges where I can select a specific passage... I think it's really great!

„Learning new songs has never been easier, in my opinion. Lyrics and sheet music are always available, no matter where you are. The ability to switch individual parts on and off is fantastic and really helps you become more confident in your own vocal range. You always have all the dates for rehearsals and concerts at a glance. Simply superb!“

„The app is very effective for independent practice. I especially like the ability to adjust the volume of my own part (alto) as needed or to check how confidently I can sing it on my own. It offers many helpful features, such as setting bookmarks, different views and selection tools.“

How cori works

Something happens between rehearsals now.

Innovative rehearsals, practice and organization. For more time making music together.
Between rehearsals

Every voice is ready before rehearsal

Choir singers practice with rehearsal recordings of the repertoire, hear their own voice clearly and get feedback while singing along. Everyone comes to rehearsal prepared.
  • Audio mixer: your voice louder, others quieter
  • Check intonation and rhythm in sing mode
  • Share announcements and hints on what to practice
  • Vocal exercises and warm-ups
  • Unlimited storage for recordings and sheet music!
cori Chor-App: Audio-Mixer zum Üben mit Stimmreglern für Sopran, Alt, Tenor und Bass – eigene Stimme lauter, andere leiser stellen und Noten mitlesen
During rehearsal

Sheet music ready, notes anytime.

All sheet music in one place. Mark breath marks, dynamics or cues directly with a stylus on any device.
  • Provide and manage sheet music and lyrics for the whole choir
  • Annotate with a stylus on tablet or smartphone
  • Your notes synced across all devices
  • Share notes live with each other

Rehearsals, concerts, setlists and announcements in one place. More time for what matters: singing together.
  • RSVPs for rehearsals and concerts
  • Build setlists for learning and concert day
