The function expects `text' to be a string. So

Thank you, now it works. And I learned how to do calculations in scheme
along the way as well. So the narrator function should be
narrator=#(define-music-function
(dim text) (number? string?)
#{
s1^\markup
\with-dimensions #(cons 0 (+ dim 2)) #'(0 . 0)
\whiteout
\override #(cons (quote line-width) dim)
\translate #'(0 . -1.5)
\wordwrap-string #text
#})

Auke
