Ah, that's something I understand...
The parser compiles the first expression:
aNotes = \relative c' { c1 e g }
N
aNotes = \relative c' { c1 e g }
#(define dummy #f)
#(if (not (defined? 'bNotes))
(define bNotes aNotes))
\score {
\bNotes
}
When the 'define dummy' is removed, it doesn't work anymore.
The doc say it is due to "parser lookahead" :

Meanwhile, I'm still struggling with the easy task of using one
identifier for another:
aNotes = \relative c' { ... }
%%From template:
\score {
#(if (not (defined? bNotes))
(define bNotes aNotes))
\bNotes
}
The intention is clear, but LilyPond/Scheme refuses to compile it

A very interesting approach, and very illustrative for the powers of
LilyPond programming! I learned a lot from your examples.

These two functions should help. (Suggestions for improvement would be
appreciated.) You will either need to define your optional music to be
Hi,
In a template file I want to check if a particular identifier has been
defined, and act accordingly.
For example:
\score {
\allMusic
\layout {
}
}
\score {
\unfoldRepeats \allMusic
\midi {
}
}
In the MIDI block, I would like to use identifier allMusicForMID
