Re: chord name e2:m7(b5)/d

[Torsten Hämmerle]

Hi Ming and Robert,

While e:min7.5-/d is the correct LilyPond coding for of the chord in
question, the standard output still does not match Ming's specification.

*"Problem"*
(leaving away the /D, just looking at the main chord here)
A minor seventh chord with diminished 5th is nothing else but a
half-diminished seventh chord. 
In this case, LilyPond's standard output will produce an Eø.
Writing Em7(b5) is just an alternative that can't be achieved without
altering LilyPond's standards.

For this very likely reason, one may specify chord-exceptions to adapt the
output to personal taste as described in  Chord Name Exceptions
<http://lilypond.org/doc/v2.18/Documentation/snippets/chords#chords-chord-name-exceptions>
 
.

The notes contained in the "template chord" always refer to tonic C, so
we'll have to specify the notes of a Cm7(b5) in LilyPond's native (Dutch)
language:
<c ees ges bes>.
As demonstrated in the link, you may specify an arbitrary markup, in this
case something like

~~~
 chExceptionMusic = {
   <c ees ges bes>1-\markup {  m\super \concat { 7 (\teeny\raise #.3 \flat
5) } }
 }

HTH,
Torsten
