Well, not all changes were _necessary_, p.e. using 'parser location'
in music-functions still works. Superfluous, though.

You could do
quoteChordSecond = \quoteChord "second" \etc

Then here:
c1 d e f g a \quoteChordSecond { b } c

# is pass-through, $ creates a copy. Music that is used exactly once is
fine to pass through.

Glad I could help.

No need for 'parser location' in music-functions for 2.19.x, you could
delete them

I'd use $music instead, refer to the Extending manual for the difference.
Although I doubt it makes a difference here, I'm used to be a paranoiac ...

Likely more robust to do:
\new ChordNames = "chrds-2" { #(skip-of-length otherNotes) }

Hi,
you could try (ee inline comments):
chordTrack = \chordmode {
\repeat unfold 2 {
c1 d e f |
}
}
%% make 'chordTrack' quotable
\addQuote "chrds" { \chordTrack }
notes = \relative c' {
\repeat unfold 8 {
c4 d e f |
}
}
otherNotes = \relative c' {
c1 d e f
%% refer to the preexisting and named ChordNames-context, to put in the quotes
\context ChordNames = "chrds-2"
\quoteDuring "chrds" {
%% while putting quotes into the relevant ChordNames-context, refer to
%% the preexisting and named Staff-context to continue entering "normal"
%% stuff
\context Staff = "2" { g1 a }
}
b c
}
\score {
<<
\new ChordNames \chordTrack
\new Staff \notes
%% initiate a ChordNames-context which may be filled form 'otherNotes'
\new ChordNames = "chrds-2"
\new Staff = "2" \otherNotes
>>
}
Not sure, if someone would call it "elegent" ...
Cheers,
Harm
