MuseScore is the world's leading free and open-source software for writing
music, with a user-friendly interface and immensely powerful features.
It is free to install on Windows, Mac, and Linux.

$ sudo snap connect musescore:cups-control
$ sudo snap connect musescore:network-manager
$ sudo snap connect musescore:alsa
But most of the application functionality works without them.
