Please take a look at the collection I've done of fiddle tunes for viola, and let me know if it looks like what you want. I'm on a long road trip, and won't have access to my computer for another month, but I think I can access my LY files, and, if not, I should be able to explain what I did. You can download the PDFs of my collection at :
Yes! I mean, it's not the exact formatting I'd like to use, but it looks like you've solved the putting centered text under the tunes, not breaking them across pages, and having an index. That's most of the major issues I'm worried about. I'd love to see your LY files to see how you are doing this.
Thanks so much,
Sol
PS It's so trippy seeing tunes I know in alto clef!
