Check out the 2021 Fiddlerman “White Christmas” Group Project.
If you're like me, there can never be too many free music sites, even if you can't begin to play the music offered
Anywho, I just found another great site, the Violin Site, that offers a boatload of free violin music, free for the download. They also offer some links to other sites. This is for "violinists" vice "fiddlers", as the music primarily consists of classical scores. It is grouped by composer, and one nice thing is that, for string ensemble scores, they offer scores for individual instruments as well as a complete score (with all instruments). At least it's that way for J.S. Bach. I just thought I'd pass this on.
