cori's player is built for practising, not just listening. Every song carries separate tracks for each voice part, so you can turn your own voice up, slow a tricky passage down and follow along — all from one screen. This guide gives you the overview and points to the deeper guides for each feature.
Open a song
Go to Setlists and open the setlist you're rehearsing. A setlist is just the collection of songs your choir is working on.
Tap or click a song to start it. The player opens at the bottom of the screen — on mobile, pull it up to see the full controls; on the web it expands into the bar along the bottom.

Player controls
Use the central play / pause button to start and stop. Drag the timeline to jump to any point, or use the 15-second skip buttons to nudge back and forth.
The previous and next buttons step through the songs in your setlist, so you can run a whole programme without leaving the player.
Choose and balance your voices
Open the Mixer tab to control which voice parts you hear. The quick presets let you switch in one tap between Own voice, Own voice louder and All voices. Tap a voice to mute or solo it, and use its slider to set the exact volume.
Start with Own voice louder so your line sits on top of the others, then switch to All voices once you're confident and want to blend in.

Change the tempo
Use the Speed control to slow a song down while you learn the notes — the pitch stays the same, so everything still sounds in tune. Wind it back up to full tempo as you improve.
Loop a tricky passage
The Repeat button cycles through repeat options. Set it to repeat the current track to drill a difficult bar over and over without reaching for play each time.
