I have managed to get this working, by adding this to .emacs=20
(unfortunately, this is not exposed as a defcustom).

(setq ly-nix-ly-path "/usr/bin/lilypond -dpreview")

Incidentally, it would be very useful if babel offered a header argument=20
for commandline switches. If there is one, it was not obvious at [1] which=20=

one it should be.

Then, this actually compiles and displays well enough:

#+name: pitches
#+begin_src lilypond -i :exports both :file pitches.png :prologue=20
\header{tagline=3D##f}
\include "english.ly"
{ c' e' g' fs' a' c'' ef'' d' }
#+end_src

Next up: I would like ":prologue \header{tagline=3D##f}" to be buffer wide. I=
=20
tried this:

#+PROPERTY: header-args:lilypond :prologue \header{tagline=3D##f}

.. but it didn't work at first.

[5 minutes]

OK, I had to refresh the buffer setup. That wasn't obvious in the=20
documentation.

So it all seems to be working now.
