Check out the “Let it Snow” Xmas 2020 Group youtube project!”
I went to this site, which has the complete book "Hill Country Tunes" free for download. It contains 95 tunes as well as other interesting commentary. This is American fiddle music, so the ornamentation is probably a little different from Celtic or Canadian music. I have yet to delve deep into the book, but thought I would share what I found.
Keep Calm and Fiddle (or Viddle) On!
