I've also had some extensive looks at the elisp-code and what I think that the 
lilypond syntax-table is supposed to accomplish is to provide different 
font-locking for different parts of the .ly file. The lyrics should get 
different font-locking from the notes, etc. Unfortunately, this does not seem 
to work as in lyrics like `a nice foo bar', the `a' gets font-locked as the 
note `a' and the rest doesn't get font-locking.

It also does define the parentheses to be normal characters, so functions like  
beginning-of-defun (C-M-a) and backward-sexp (C-M-b) and their functional 
opposites don't work. Also it prevents the blinking of parentheses.

Unfortunately, all of the above doesn't bother me enough to do something about 
it ;-) But if you can make LilyPond-mode work like it should[1], you have my 
vote!

In all the gnu-emacsen I've used (19 - 22) this is the default key-binding.


HTH,

[1] It should do the emacs thing when it comes to parentheses, but it should 
also do context-based font-locking. I do have a sample-file lying around 
somewhere, where I use a function to determine the font-locking a word 
receives. Perhaps something similar could be done here? See 
<http://zaaf.nl/emacs/beatnik.html> for font-locking based on the scrabble 
value of a word.
