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).

Hi Urs,

I assume you know to build the music-expression for the score in scheme. 
With that you can make use of #(scorify-music mymusic).
That creates a score object *and* creates the necessary music for << \\ 
>> constructs an thew like. If you don't need that you can simply use 
#(ly:make-score mymusic).

Hi all,

I have a scheme-function that returns a \score expression, and I'm 
sure I wouldn't have to hop around between LilyPond and Scheme syntax 
like this:


make-score =
#(define-scheme-function (movement-path)(symbol-list?)
   #{
 \score {
   <<
 \new GrandStaff <<
   #(get-staff movement-path 'clarino-one)
   #(get-staff movement-path 'clarino-two)
   #(get-staff movement-path 'corno-one)
   #(get-staff movement-path 'corno-two)
 >>

 #(get-staff movement-path 'tympano)

 \new ChoirStaff <<
   #(get-staff movement-path 'soprano)
   #(get-staff movement-path 'alto)
   #(get-staff movement-path 'tenor)
   #(get-staff movement-path 'bass)
 >>
 \new StaffGroup <<
   \new GrandStaff <<
 #(get-staff movement-path 'violin-one)

 #(get-staff movement-path 'viola)
   >>
   #(get-staff movement-path 'bc)
 >>
   >>
   \midi {}
   \layout {}
 }
   #})


The function is also called from within Scheme code, so I would like 
to write the same using Scheme only, without switching to LilyPond 
with #{ #} but also back to Scheme within these expressions.


How would I go about this and/or where would I look up the reference 
for this?


Thanks
