I see many references to this on the mailing list, but are these files anywhere standard? I grabbed an old jazz-chords.ly
from some mailing list message, but then it didn't work when I included it, and it had no version number so I couldn't figure out how to convert it.
What I actually want to do: single line melodies with chord symbols. I'm using the "Simple lead sheet" from http://lilypond.org/doc/v2.16/Documentation/snippets/chords
as an example, but I cannot for the life of me figure out how to do things like get an F7b9 symbol in there. Most of the "chords" examples I find lying around seem to be built around the idea that you want to show a bunch of pitches of a chord and then get the name automatically? What am I missing?
