Interesting discussion- I’ll have to ask DD about MuseScore. The professor she has right now is asking for everything to be submitted handwritten, which is unusual in her experience. She tells me she still uses Sibelius, and has been able to download it even though we stopped paying for the subscription several years ago- apparently the lack of updates hasn’t been an issue for her (though I suspect it might make a big difference depending on what one does/how one uses it).
