Leader playback control
The leader controls tempo, repeats, and the starting measure, so the whole ensemble moves as one. In personal-practice mode, each player loops just the passage they need.

Each part, prepared apart, comes together on the same measure.
The friction of rehearsing together
Finding scores, aligning parts, checking who's ready. The time to actually play together keeps getting pushed back by prep.

The latest scores, parts, and edits are strewn across chat and email, so you hunt them down before every rehearsal.
Page turns, finding repeats, checking notes — every leak of time is time you can't spend playing together.
It's hard to tell how far each part has prepared, so rehearsal time goes to status checks.
So Opusis gathers all of that prep into one rehearsal room.
Prepare ahead
From uploading scores to planning rehearsals and scheduling — everything that used to be scattered lives in one rehearsal room. On the day, there's nothing to line up; you just start playing.

What you can do
The leader controls tempo, repeats, and the starting measure, so the whole ensemble moves as one. In personal-practice mode, each player loops just the passage they need.

Leave a note on a specific measure and it shows up on everyone's screen.

Highlight only your part, or hide the ones you don't need.

Upload a standard score and parts, measures, and tempo are recognized automatically.

Desktop, tablet (portrait and landscape), and mobile landscape — every screen joins the same room.

Free during beta. Upload a score and invite your team, and from your next rehearsal you can play together right away.
Start for freeOpusis comes from “Opus is” — because a work isn't finished by the score alone. A work is made through rehearsal.
