ChoirKey helps singers learn their choir music with custom rehearsal tracks, flexible playback tools and a scrolling score, built for real practice. Enter your unique Choir Key to access your choir's repertoire, then choose the tracks you'd like to rehearse in your own time. Hear your own vocal line clearly, blend it with the accompaniment or a choral reduction, slow difficult passages without leaving the player, and loop short sections until you're confident with your part. When score files are available, ChoirKey lets you view the sheet music in the app and follow along as the audio plays. You can also download tracks for offline practice, keep favourites close to hand, and manage stored files from your repertoire list. Key features: - Secure access to your choir's custom rehearsal library - Separate vocal-part and accompaniment playback controls - Tempo adjustment for learning difficult passages - Repeat loops for focused practice - Score viewing with audio-following support where available - Favourites and local storage management - Offline access to downloaded rehearsal materials ChoirKey is designed for choir members, choral leaders, teachers, and singing groups who want rehearsal preparation to be quicker, clearer, and easier to fit around everyday life. Note: Access to most libraries requires a Choir Key provided by your choir, organisation, teacher, or rights holder.

About

Chorustr

Read full description

Chorustr is a choir practice app that helps singers learn their parts between rehearsals โ€” so choir leaders can spend more rehearsal time making music. Give your choir one simple place to practise the music you're working on. Singers can focus on their own voice part, work at their own pace and arrive at choir rehearsal better prepared. Whether they sing soprano, alto, tenor or bass, Chorustr gives everyone the tools to build confidence between rehearsals. PRACTISE YOUR PART, YOUR WAY Chorustr's part mixer lets singers choose how much of their own part and the rest of the choir they hear. Isolate a part while learning it, emphasise it as confidence grows, then practise with the full choir mix. Backing and click tracks can also be adjusted where the choir provides them. WORK ON THE DIFFICULT BITS Slow the music down when you need more time, repeat sections that need extra attention and jump quickly to useful points in the song. Instead of repeatedly finding your place in a long rehearsal track, spend your practice time on the passages that actually need work. KEEP THE MUSIC IN FRONT OF YOU Follow lyrics, view the score and read notes from your choir while you practise. Everything you need for a piece stays alongside the music you're learning. BUILT AROUND YOUR CHOIR Chorustr isn't trying to be an everything app for running a choir. It's focused on the journey from rehearsal, through practice, to performance. Choir leaders can keep their repertoire organised in Dropbox and choose exactly which songs and practice tracks members can access. Chorustr helps protect those materials by keeping access tied to active choir membership. At rehearsal, members check in with a quick QR scan from your choir's branded welcome screen, giving leaders a simple attendance record. New members can use the same experience to join the choir and get started with Chorustr. Upcoming concerts and events keep the practical details in one place, while focused set lists connect what you're performing directly to what singers need to practise. And rather than trying to replace the tools your choir already uses, your choir page can point members to useful resources such as your existing WhatsApp groups. BETTER PREPARED. BETTER REHEARSALS. Everyone learns at a different pace. Chorustr gives singers the space to learn their part, build confidence and arrive ready to make music together. For choir leaders, that means less rehearsal time reminding people how their part goes โ€” and more time listening, blending, shaping and singing together.
