Well, here is an example.  Since you won't add variables to macros, I
*have* to use m4 or something similar to avoid extremely unreadable
ly files.  Other suggestions how to handle this are highly welcome.


  changequote([, ])
  define([TextVShift],
         [property Voice.TextScript \set #'extra-offset = #'(0 . $1)])
  changequote(,)

  < { \TextVShift(1) s1^"\\textbf{\\large Langsam}" } \\
      R1 > |
