This seems to work for me:

#(define-public myBool #t)

myMusicFunc =
#(define-music-function (parser location) ()
    (display "\nIn myMusicFunc\n")
    (display "myBool: ")(display myBool)(newline)
    (set! myBool #f)
    (display "myBool: ")(display myBool)(newline)
    (make-music 'SequentialMusic 'void #t))

\relative c'' {
  c4  
    \myMusicFunc
    c c c 
}


Was there something else you were trying to do?
