This is a small git repository (13 commits) with Lily sources of a choir part from 3rd movement of Antonin Dvorak's Stabat Mater. I think it's a very good example of LilyPond at work, problems with default output, and the beautification progress itself, especially that the commit history was specifically hand-crafted to show and document each stage of beautification. I think it could be an entertaining and informative demonstration to show these commits with respective compiled scores to people in music industry. Using interactive git rebase you could even add some fake typos inside :P This engraving was created by me from a version used by my choir. I don't know what the original edition was, but i'm pretty sure that it should be in public domain, so consider yourself free to use it under the terms of GNU GPL 3 or higher. Feedback is welcome!
