About Open Opus

Finally, classical music and online streaming working together

Support Open Opus, Concertmaster and Concertino and keep transforming the online classical music experience

Online music is here to stay. But, the most successful platforms, Spotify and Apple Music, were created for popular music, based on singers, albums and, specially, tracks. Classical music demands a very different approach: it is based on composers, works, performers (a plenty of them) and movements. Concertmaster and Concertino bring the complex structure of classical music to Spotify and Apple Music. It combines composers and works info from the Open Opus library with automated analysis of the streaming services' metadata.

The result? Free, open source apps that make online streaming and classical music work together, at last.

We need your support!

Concertmaster, Concertino and Open Opus are free to use but they run on web servers that cost us money. You can help us by being a patron! $5 supporters get early access to new versions and an exclusive online board to talk about our future features.

Free and open source

Our software is open source. This means that you can not only see how it was made but contribute yourself with code! Bug fixes and new features implementation are always needed. And, of course, you can fork our code and create your own software - why not?

For the love of music

Open Opus composers and works database is an open, wiki-style repository of classical music metadata. You can review existing info or add new entries to the database - any help will be appreciated!
