Chord Name Exceptions

[Gabriel Borin]

Hello,

I have been trying to write a bass part for a big band. Although I am mostly happy with the general output of chord names, I don´t like half-diminished notation in Lilypond. I prefer the descriptive "m7(b5) or min7(b5)".

I have been trying to use the snippet under this link with no success:  https://lilypond.org/doc/v2.19/Documentation/notation/displaying-chords.en.html

Can somebody help me, please?

Sincerely,

Gabriel Borin
