Opera One
Read full descriptionHide full description
Your singing studio, always with you. Opera One brings together what you need to study an aria: the orchestral backing track, a score that follows the music, and a recording of how you sang it. SING WITH THE ORCHESTRA Every piece in the catalogue comes with its own backing track. Choose an aria, press play and sing: the tempo is right, the key is the one in the score. THE SCORE FOLLOWS YOU, NOT THE OTHER WAY AROUND While you sing, the score scrolls in time with the track. Want to go back over a passage? Scroll it with your finger, and when you are ready a single tap hooks it back to the music. No pages to turn mid-phrase. WATCH YOUR PERFORMANCE BACK Record in portrait, with your voice and the backing track together. The video is saved to your Photos library, yours alone: review it, compare attempts, share it with your teacher if you want to. A REPERTOIRE THAT KNOWS YOUR VOICE Operatic arias with their text, composer, source work and tessitura, so you can tell at a glance whether a piece sits well for you. PRIVACY Your recordings stay on your device and in your Photos library. You can export or delete your data whenever you like, straight from the app. ā Opera One Premium unlocks the full catalogue and study features. ⢠Monthly: EUR 9.99 ⢠Yearly: EUR 89.99 Prices may vary by country.

Your voice is different every day. Your warm-up should be too. VoxReady builds one clear vocal warm-up from the range that feels comfortable today, the time you have, and what you are preparing for. Choose a rehearsal, lesson, audition, recording, performance, daily practice, or gentle reset. VoxReady assembles the sequence and generates the accompaniment locally. BUILD A ROUTINE FOR TODAY ⢠Set exact low and high notes ⢠Choose 5, 10, 15, or 20 minutes ⢠Select your goal and exercise focus ⢠Adjust tempo with the built-in metronome ⢠Reorder, remove, or add exercises SING WITHOUT SEARCHING FOR TRACKS Follow the timer, pitch lane, and current exercise. Pause, repeat, or skip whenever you need. Every pattern is placed inside the range you selected. KEEP A PRIVATE PRACTICE RHYTHM Save routines, schedule warm-up reminders, and add a short private reflection after each session. See your consistency without turning practice into a score.

Stop if an exercise feels painful, strained, or unusually uncomfortable.
