Beta · Free during pilot
Share sheets with your ensemble — for a week, then they vanish.
Make a private room. Upload your annotated sheet music (PDFs). Send the link to your orchestra members. They open the sheets on their own tablets, phones, or laptops. After seven days everything auto-deletes — or you can end the room early.
No sign-up for your members — they just open the link.
How it works
Three steps, no apps to install
Create a room + upload
Sign in, name your room, drag in your PDFs. Each file can be up to 25 MB. Up to 30 files per room.
Share the link
Copy the room URL. Send it through Messenger, email, a group chat — however your ensemble communicates.
Members view & download
No sign-up. They tap a sheet, it opens in their device's PDF viewer. They can save or print as needed.
7-day lifetime, then gone
Each room expires 7 days after you create it. We delete the files automatically — nothing lingers on our servers. End the room early to delete immediately.
Private by URL
The room URL is a long random token (16 characters). Only people with the link can view. We don't list rooms publicly or index them in search.
Bring your own annotations
Mark up sheets in forScore, GoodNotes, Notability, MuseScore — whatever you already use. Export as PDF and upload here. Your bowings and fingerings come along.
No collaborative editing
Rehearsal Rooms is a shelf, not a whiteboard. Each member views the PDF on their own device, independently. No shared cursors, no live drawing — just a calm place to read.
Before you upload
Only upload sheet music you have the right to share with your members — for example: public-domain editions, material you own, scores your ensemble has licensed or purchased parts for, or your own arrangements. Don’t upload commercial editions you haven’t paid for.
We’ll ask you to confirm this on every room you create. If you spot something on Rehearsal Rooms that shouldn’t be there, please report it.
FAQ
Is this free?
Yes, during the beta. We may add a paid tier later for ensembles needing longer retention or larger rooms, but the free plan stays.
Do my members need a Corona Strings account?
No. Only the room creator (you) signs in. Members just open the URL — they can view and download right away.
What happens after 7 days?
The room and all its files are deleted automatically. If your rehearsal cycle is longer, just create a new room when needed and re-upload.
Can I draw on the sheets inside the platform?
No. Use your favorite annotation app (forScore, GoodNotes, Notability, MuseScore) to mark up the PDF before uploading — your annotations are baked into the file and travel with it. Rehearsal Rooms just hosts and displays.
Will Corona Strings see what's in my room?
Only if there's a takedown report or a serious problem. We don't routinely look inside rooms — they're private to you and your members.
Can I have more than 30 files in a room?
Not in this version. If you need more, split into two rooms or let us know what use case you have — feedback at hello@coronastrings.com.
