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

The subscription page has been rebuilt, and Home has a new opening.

• Subscription: the concert hall behind the whole page, with prices, button and terms at the bottom, where the photograph is dark and text reads.
• Home opens with the aria's title in the brand typeface, and the background takes its colour from the album cover.
• Difficulty is no longer shown: it was 5 for every piece.
• Italian TalkBack now says "Riproduci" for the listen control.
