There's a snippet for this, but here's a rebroadcast:
chExceptionMusic = {
<c e g d'>1-\markup { \super "add9" }
}
chExceptions = #(append
(sequential-music-to-chord-exceptions chExceptionMusic #t)
ignatzekExceptions)
Chords =
\chordmode {
\set chordNameExceptions =
#chExceptions
d1:9^7
}
The exceptions you define applies to any chord of that voicing, regardless of the key. I do
all of my exceptions in the key of C, for clarity.
