Hi Jean,
I just finished my reply when I saw your next message. :)
Sorry, I was starting to forget about the "transposing" bit.
Well, how about
\version "2.22.2"
t =
#(define-music-function (text) (markup?)
#{
\once \set chordNameFunction =
#(lambda (sorted-pitches bass inversion context)
(let* ((root (first sorted-pitches))
(root-namer
(ly:context-property context 'chordRootNamer))
(root-markup (root-namer root #f))
(bass-markup
(if (ly:pitch? bass)
#{ \markup { / #(root-namer bass #f) } #}
"")))
#{ \markup { #root-markup \super #text #bass-markup }
#}))
#})
bass = \withMusicProperty bass ##t \etc
myChordNames =
\relative {
\t "6-9" c1
\t "6-9" << c \bass g >>
}
<<
\new ChordNames \myChordNames
\new ChordNames \transpose c d \myChordNames
>>
Yeah, judging from some quick tests, that seems to do what I want. Thanks a lot! This is very useful.
I still think it could be nice to try to write a longer-term solution. I
saw it was you who wrote that newer Current_chord_text_engraver, with
the goal of making a chord name grid. Do you think there would be any interest in specifying the chord suffixes like that, directly from markup? I'd be happy to contribute to some
other kind of chord engraver or chord name function that behaves like that, if
anyone else thinks it's useful. (I imagine jazz musicians might?)
To clarify again: the immediate reason was
that if I transpose all of the pitches in a chord and then naturalize
double accidentals, it messes up the intervals and the symbol changes.
The
longer-term reason is that to me, at least in the specific use case of printing
a harmonic background, the layer of calculating chords from internal pitches is redundant anyway. There are many
ways to think about a chord, and I change the way I think about them all
the time: I just want to write it down and I don't need LilyPond to
reason about it. :) (Although a root and a bass note are still useful.)
Cheers,
Koen
