You can read about the way scores are processed in Erik Sandberg's masters
thesis:

<http://lilypond.org/web/images/thesis-erik-sandberg.pdf>

As far as determining the internal representation of any music, the easiest
way to do that is through the use of \displayMusic, which is documented in
Notation Reference 6.3.1. Displaying music expressions.

<http://lilypond.org/doc/v2.12/Documentation/user/lilypond/Displaying-music-
expressions>

Jon, could you add

@cindex displaying music expressions
@cindex internal representation, displaying
@index displayMusic

to that section of the docs?

Thanks,

Carl
