OK
here's a short hint created with the help of displayMusic:
% a dummy definition of create-staff
#(define (get-staff what)
(make-music 'ContextSpeccedMusic
'create-new #t
'property-operations '()
'context-type 'Staff
'element #{ c''4 #}))
% a scheme representation of \new StaffGroup
$(make-music
'ContextSpeccedMusic
'create-new #t
'property-operations '()
'context-type 'StaffGroup
'element (make-music
'SimultaneousMusic
'elements (map get-staff '(oboe flute))))
OK, I see how I can go about this.
But actually I have the impression that this will cause much more pain
that the original state with switching between LilyPond and Scheme. I
must say I get totally lost in that (considering that there are numerous
properties to get from function calls.
The point I got to
(https://git.openlilylib.org/bfsc/kayser/blob/Change-make-staff/includes/lib/make-staff.ily#L240)
does compile and seems to produce Staff objects but obviously the music
in it doesn't get through (note that this is another point than the
original make-score, this is in make-staff instead) ...
Well, maybe I return to that WIP commit after my brain cools down a
little bit again ...

Hi Urs,
I assume you know to build the music-expression for the score in
scheme.
No, not really.
I can replace \score {} with (ly:make-score) but that doesn't really
help me.
I have no idea how to map the nesting of the parallel contexts to
Scheme expressions within a single expression.
(get-staff returns Staff objects, but at a later (or earlier) point I
will also want to create the Staff with Scheme (the music itself will
stay in LilyPond language files).
