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.
