Hi,

some comments.


* Couldn't the print-method be added as a property to 
scm/define-music-types.scm for each type? (or perhaps as a list of methods?)

* I think it is better to call the routines xxx-display-yyy iso. 
xxx-print-yyy, to prevent any confusion between front-end and backend.

* If possible, the meta-machinery for printing and the actual methods 
should be in different files, the latter file being called 
define-music-display-methods.scm

* I notice that you mention GOOPS in a comment. We do use goops in a 
couple of places, but we should minimize this. I do not want LilyPond to 
be completely dependent on GUILE. It would be nice if we could switch to 
a different scheme interpreter with a relatively small amount of work. 
(specifically, I'm considering MzScheme for this.)
