Re: (doc help) scheme: why not start with define-music-function ?

[Mats Bengtsson]

I would start with the last example of current 11.1.6 (or some other
similar example(s)). Then, we can introduce the basics of how to
replace some of the embedded LilyPond code with Scheme code
to get more flexibility. This second step, of course, is an excellent
example of how to use \displayScheme.
