Ok, I just updated "chord-names.scm" and "american-chords.ly" to incorporate
Atte's jazz chords (c-n.scm) and supply a missing seventh chord (a-c.ly).
There's no need to use scheme in your .ly file for jazz chords: Just use
\property ChordNames.chordNameStyle = "jazz" where appropriate.

I did check out your previous post (the one with 'atte-jazz-chords.ly) and I
saw that I was missing dominant 7th flat 5. D'oh! Cmaj6 spelled as C6 is
also probably better, so that would make only 5 deviations from the american
style. I know of the "+" being shorthand for "aug", but I think that comes
down to a matter of taste (I know more than a few people who hate using "+"
for "aug", but I couldn't begin to tell you why).

Look at my chord-names.scm for the appropriate place (after
'names-alist-jazz') to make any changes you need to in order to make a
proper "jazz" style and post it here so it can be incorporated...
