Yes, I have to change the value of myBool within a
stencil callback.
Like this:
\version "2.13.3"
#(define myBool #f)
myMusicFunc =

From what I see on the console output, the calls of \myMusicFunc
are evaluated first, so myBool is #t and the callbacks come in action
afterwards (the first slur claims #t, every other slur reads #f), so
apparently they don't influence each other the way I expect

For the music-function you can do this:
% you can also do:
% mybool = ##f
#(define mybool #f)
Why not just change this to
#(define-public mybool #f)
then use mybool

I tried this first, but it seems that it doesn't work inside a

Sorry if this is a stupid question, but here im totally stuck:
I need to define a boolean which is to be changed within a music-function
and a stencil callback.
I tried
#(define mybool #f)
at the beginning and later
myfunc = #(define-music-function (parser location note) (ly:music?)
