Hi all. This is very interesting.
I quickly tried setting the org-babel-default-header-args:LANG using
exactly
the src emacs-lisp example block above.
However that variable remained nil before and after org export lilypond to PDF.
Am sure I must have done something wrong.
Thank you for drawing my attention to that variable, as it seems the right
place
for lilypond headers and options too.
Off-topic: Oliver is exporting/engraving to a fixed-resolution png. An
alternative
is to export scalable vector graphics of the score to PDF.
