I'm currently working on a collection of fiddle tunes transcribed/transposed for viola. It includes copyrighted music, but I have explicit permission from the copyright holders to post the collection publicly on the internet. The collection is produced using LilyPond and Frescobaldi, although I was planning to do the introductory materials in another program and post the whole production as PDF. Would my collection be acceptable with copyrighted (copywritten?) materials? I could remove the copyrighted materials, but that would certainly make the collection less useful to other violists.
All the best,
Ralph
