Since lilypond only recognizes one possible pitch per scale degree,
you need to spell one of the b's as something else.
I've first tried this out for #9 b9 chords, spelling the b9 ike
bes:1.3.5.7.8+.9+
For some reason, the exceptions does not seem to work with 8-, so looks
like you'll have to spell it
bes:1.3-.5-.6.7+
\version "2.19.83"
jazzChordDefinitions={
% Just to demo that we can define the base diminished 7 chord
<c ees ges beses>-\markup { \super "o!" }
% I am not sure why this one does not work
<c ees ges beses ces>-\markup { \super "o7(△7)" }
% This one works
<c ees ges a b>-\markup { \super "o7(△7)" }
}
jazzChordExceptions=#(append
(sequential-music-to-chord-exceptions jazzChordDefinitions #t)
)
myChordSequence = \chordmode {
% For reference, two ways to specify the base diminished 7th chord
% Since 7 implies minor 7, the diminished 7 is 7-, and major 7 is 7+
bes1:dim7
bes1:1.3-.5-.7-
% Here are two ways to specify the enharmonic pitches
% using the base diminished 7 plus a lowered octave
% It is not clear to me why the exceptions don't work for these
bes1:dim7.8-
bes1:1.3-.5-.7-.8-
% Here is the one that works, by respelling the diminished 7th
interval as a 6th.
bes1:1.3-.5-.6.7+
