Hi Sally,
While your article is interesting, lilypond is a tool for advanced music engraving, and this mailing list and the website focus on that and the use of the lilypond engraving software pretty much exclusively rather than music theory or practice matters. You may find a more appropriate forum elsewhere. There are lots of forums on theory.
The only thing I can think of that is relevant is that one of the list members engraved a very nice circle of fifths using lilypond techniques some while back - not easy in programs that can generally only do straight line layouts.
