ChoirZone is your personal practice studio for choir singing. Bring your score, learn your part, and walk into rehearsal ready. PRACTICE STUDIO See the sheet music and hear each voice at the same time, always in sync. Solo your part, mute the rest, slow it down, and loop the tricky four bars until they finally stick. Works with PDF and MusicXML scores. MARK UP YOUR MUSIC Add notes and musical stamps exactly where you need them, or draw freehand with your finger or Apple Pencil. Read continuously or page-by-page, like a book. TRAIN YOUR EAR AND VOICE On-device exercises that actually listen to you: interval training, sight-reading, rhythm, and a "drift" exercise that shows when you're slipping off pitch. Check your vocal range, warm up, and record yourself to listen back. All pitch detection runs privately on your device. YOUR WHOLE CHOIR IN ONE PLACE Share the set list, see who's coming to rehearsal, and point everyone at the exact score. Your singers arrive already knowing the notes β so rehearsal is for making music, not teaching parts. FREE TO PRACTISE ChoirZone is free for your own practice. Running a choir with members is available as a subscription. Made by choir singers, for choir singers. Support: support@choirzone.com Privacy: https://choirzone.com/privacy
