This article makes a lot of good points. I think about doing some of the things they recommend that the current SerpentPublications.org transcriptions don’t do. I don’t think I’d have even as many people to play with as I do now if I kept the original clefs. I’ve had trouble with the lilypond spacing when I’ve tried to go to the original note shapes, but I could work harder. And certainly I should do more work on transcribing the mensuration symbols better. And I’ve been pretty lazy about putting brackets in for the ligatures, which isn’t hard at all.
