I think I meant that, when I wrote that list of chords & scales in chord
-names.scm, I didn't intend to be able to get the chord "C" out -
instead I want it to print "Cmaj7", since that signifies "use the C
major scale" to a jazz musician (or at least, to me :).

Yeah - I want to be able to type in a scale and get lily to print out
the appropriate chord/scale symbol.
This seems unnecessary for, say, a major 7th chord, but what about some
of the more complicated scales? e.g. whole tone. Or what about user-
defined scales?

This occurs in the 4th bar of the file ChordTest.ly which I sent. Bar 4
looks like Bar 5, but actually the notes are specified in a different order.

Well...I've got an idea, but yeah, it might be too simplistic. Who else
uses chord symbols other than for jazz, or pop charts? Surely they're
not used in classical music?
NB. My "p.s." there wasn't a criticism! I think lily is great. I've
just typeset an arrangement of "Summertime" using that modified chord-
names.scm, and it's looking sweet.
gav.
