Thanks again, but now I've tried to use this ...

I'm assuming that \default and \markup return stencils, but I don't seem
to be able to pass them to stencil-add.

Reading the manual, I tried the following two:#

stencilAdd = #(define-music-function (parser location stencila stencilb)
(ly:stencil? ly:stencil?)
        stencil-add stencila stencilb
)

#(define (combineStencils stencil-a stencil-b)
        stencil-add stencil-a stencil-b
)

which seem to compile fine (and I get the impression they're actually
identical, just defined differently :-) But both of them object when I
try to pass them any arguments. I get "unexpected \default" or
"unexpected \markup" or "unexpected STRING" or whatever ...

\stencilAdd { \default \markup "Little Bird, Little Bird" }
\combineStencils \markup "123" \markup "abc"
\combineStencils  "123"  "abc"

E:/Documents and Settings/Anthony/My Documents/My
Music/lilypond/Concert/_ManOfLaMancha/voiceStaff.ly:71:22: error: syntax
error, unexpected STRING
\combineStencils  "123
                      "  "abc"

Am I wrong in thinking \default and \markup return stencils? Or what's
going wrong? It seems clear to me that I'm not passing in what's
expected to the function, but, to my (very limited) understanding, it
all appears correct...

Cheers,
Wol
