Hi,
I am using org-babel to create music sheets with lilypond.
For some reason the fontification is not working anymore:

[2. text/x-org]
#+begin_src lilypond

  \relative c' {
    c d e f g
    }

#+end_src

[3. text/plain]
The syntax highlighting breaks when entering the "{". The error is:

Org mode fontification error in #<buffer dreiklang_improvisation.org> at 80
(80 is the line with #+end_src)

GNU Emacs 29.0.90 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.37, cairo version 1.16.0) of 2023-04-26
Org mode version 9.6.4 (release_9.6.4-9-g8eb209 @ /usr/local/share/emacs/29.0.90/lisp/org/)
GNU LilyPond 2.24.1 (running Guile 2.2)

Thanks for any help.
Regards,
Jonas

This is a problem with lilypond:

Debugger entered--Lisp error: (void-variable font-lock-reference-face)
  (eval font-lock-reference-face t)
  (#f(compiled-function (highlight) "Apply HIGHLIGHT following a match.\nHIGHLIGHT should be of the form MATCH-HIGHLIGHT, see `font-lock-keywords'." #<bytecode -0xf53eae0ec5f928c>) (0 font-lock-reference-face t))
  (font-lock-fontify-keywords-region 1 42 nil)
  (font-lock-default-fontify-region 1 42 nil)
  (font-lock-fontify-region 1 42)
  (#f(compiled-function (beg end) #<bytecode -0x19f31ec42bd98447>) 1 42)
  (font-lock-ensure)

`font-lock-reference-face' is an obsolete variable that has been removed
in Emacs 29.
