About this app

Opera One is a practice tool for singers. You choose an aria, the orchestra plays, you sing over it — and then you hear yourself back, in time with the music.

THE REPERTOIRE
Arias with professional backing tracks, organised by voice type — soprano, mezzo-soprano, contralto, tenor, baritone, bass — and by level, so you can tell at a glance whether a piece is for your voice.

THE SCORE
The score stays on screen while you sing, so you can follow the line instead of remembering it.

YOUR PERFORMANCE
Record with the microphone, or with the front camera as well. Opera One lines your voice up with the backing track, so what you play back is one performance and not two separate files. Listen to it, go back to the phrase that went wrong, then keep it or discard it.

SUBSCRIPTION
The full repertoire, the score and the recording are part of the subscription, which renews automatically until you cancel it from Google Play.

Opera One is made by Lisari.
Study your repertoire, sing over the orchestra, and listen back to yourself.

What’s new

Fixes to singing, right where the app does the thing it exists for.

• The score is visible while you record: pages were black ink on a black background, effectively invisible.
• Takes now reach playback: aligning your voice with the backing track failed every time, and a take always ended in an error.
• Each new take restarts the backing track from the beginning, instead of resuming where the previous one stopped.
