% I tried the following for note-name->lily-string (which I changed to define-public):
% This does not work at all:
%   #(use-module (scm display-lily))
% This works, but then $defaultlayout is not available any more:
%  #(ly:load "define-music-display-methods.scm")

#(define add-one-note-score 
   (let ((pitch 0))
