Re: jazz chords in LilyPond

[PabloZum]

Thanks, Tao, but that's the Chord Name Chart I just mentioned. A longer chart is here:

 

http://lilypond.org/doc/v1.9/Documentation/user/out-www/lilypond/Chord-name-chart.html

 

However, this chart is misleading. Take the case below.

 

<<
   \new ChordNames {
             \set chordChanges = ##t
             \chordmode {  a2:m7 b:9 c:dim7 d:13  }
     }

  \new Voice = "one" { \autoBeamOff
    \relative c' { \key c \major  \time 4/4  a2 b c d }
    }
   >>

 

Notice that Am7, B9 and Cdim7 come out fine, but D13 appears as D9/add13. What to do for A7b9? If you follow the Chord Chart and input "a:7/b9", you get an error message calling it "spurious garbage following chord".

 

There should be a list somewhere, like:

 

a:min7 > Am7

a:aug > A+

??? > A7b9

 

LilyPond's chord name system seems OK up to a point, and I'd like to give it a try first, though it could do with further polishing.
