Chorustr

About this app

Chorustr is a choir practice app built for singers who want to learn their part properly. Whether you are a new chorister or an experienced one, you can play your own voice part, slow tracks down, loop the tricky bars, and rehearse offline wherever you are. Every practice track stays on your device without a connection, so you can prepare on your commute, in the park, or in the ten minutes before rehearsal starts.

🎛️ HEAR YOUR PART, YOUR WAY
Set your voice part once and Chorustr emphasises it on every song, automatically. When your choir provides stem tracks, unlock a live mixer with per-track faders and four one-tap presets:
• All Parts — the full ensemble, just like rehearsal
• Emphasised — your line boosted and the others pulled back
• Solo — only your part, everything else silent
• Muted — sing along with your part switched off to test yourself properly

✈️ PRACTICE ANYWHERE
Songs download to your device and play with no internet connection — on the train, in the car, or at home. New songs from your choir leader appear automatically the next time you open the app. No links, no manual downloads, no fuss.

🐢 MASTER THE HARD BITS
Slow a difficult run down to half speed — pitch stays the same. Drop loop markers around any tricky passage and repeat it on a loop until it sticks. Star the songs that need the most attention and run a focused session with only those pieces.

📄 LYRICS AND SHEET MUSIC
If your choir leader uploads a PDF alongside a track, it appears right in the app. Follow the words or the notation while you listen, without switching apps.

🎭 TWO MODES FOR HOME AND REHEARSAL
Switch between Practice mode (audio player, for home practice) and Rehearsal mode (sheet music only, for when you're singing in the room) from the top of the songs tab.

🚀 SECONDS TO SET UP
Download the app, enter the choir code your leader gives you or scan a QR code at rehearsal, choose your voice part, and your songs start downloading immediately.
