About

Chorustr

Read full description

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 — soprano, alto, tenor, or bass — and Chorustr emphasises it on every song, automatically. Switch temporarily for any track without losing your default setting. When your choir provides stem tracks, unlock the live mixer: drag faders to balance your part against the rest of the choir with fine-grained control. Four one-tap presets make it even faster: • All Parts — the full ensemble sound • Emphasised — your line cut through clearly • Solo — only your part, nothing else • Muted — sing along with your part silenced to test what you really know PRACTICE ANYWHERE, ANY TIME Songs download automatically when you first open the app. Once they're on your device, practice on the train, in the car, or wherever inspiration strikes — no internet required. When your choir leader adds something new, it appears the next time you open the app. No links to click, no files to download manually. TACKLE THE TRICKY BITS Slow down a difficult passage without changing the pitch, then speed back up once you've nailed it. Drop custom loop markers around any section of a song and repeat it until it's second nature. Star the songs that need the most work and run a targeted session with only those pieces. LYRICS AND SHEET MUSIC INCLUDED Follow along in the app while you listen. If your choir leader uploads a PDF — lyrics sheet, notation, or both — it appears automatically alongside the audio. TWO MODES FOR EVERY SITUATION • Practice mode — tap a song to open the player and work on your part at home • Rehearsal mode — disable audio and tap any song to pull up its sheet music when you're singing with the group JOIN IN SECONDS Download the app, enter the choir code your leader gives you (or scan the QR code at rehearsal), pick your voice part, and your songs start downloading straight away. There's no complicated setup. --- Chorustr is free to download and use as a choir member. A subscription is required for choir leaders who want to set up their own choir.
