Practising with Sing-Along and exercises
Use real-time pitch feedback to practise your part and warm up with exercises.
Mobile app
Sing-Along turns practice into a game: you sing your part while cori listens through your phone's microphone and shows, in real time, how close you are to each note. Pair it with the built-in vocal exercises to warm up and steadily improve. Both live in the cori mobile app.
Sing-Along and exercises use your microphone, so they're only available in the cori app for iOS and Android — not in the browser. The first time you use them, allow microphone access when prompted.
Sing along to a song
In your setlist, tap the on the song you want to practise. This opens the Sing-Along setup for that song.
Pick the part you want to practise under Which voice do you want to practice?. You can also Select part to loop one tricky passage, or leave it on Whole song. Then tap Start.
After a short Get Ready! countdown the song plays. Sing your part out loud — cori listens and draws your voice on screen as you go.
Reading the pitch feedback
As the song plays, the notes of your part scroll towards the sing line — the marker that shows "now". A coloured line traces the pitch you're actually singing, so you can see at a glance whether you're sitting inside each target note or drifting sharp or flat. Land a note cleanly and a little pulse confirms the hit; at the end you get an accuracy score, and a new best! badge when you beat your previous run.
You don't need a soprano's range to practise the soprano line. cori automatically detects if you're singing a whole octave higher or lower and follows you there, so anyone can practise any part. You still need to hit the right note within your octave — only the register is forgiven.
Warm up with exercises
Open Home›Exercises to reach your learning path of guided vocal exercises. They start gently and unlock harder levels as you earn stars. The types include:
- Warm-up — easy patterns like Do Re Mi to wake up your voice.
- Range — gradually climbing or descending lines to stretch your range.
- Sustain — holding a steady note without drifting flat.
- Harmony — keeping your note while other voices sound around you.
- Jumps — leaping cleanly between wider intervals.
Each exercise gives the same live pitch feedback as Sing-Along, plus a star rating and your best score so you can track progress.
Headphones keep the backing track and exercise tones out of your microphone, so cori hears only your voice and the pitch feedback is far more accurate.
