Hello Urs,

in my function I used define-music-function ( the - got lost during copy&paste).
The error locates also the error at line 46 in addons.ly (thats where the
function definition is located).

My question is: why does lilypond expect music when I put ly:pitch? as the
predicate?



rel = #(define-music-function                                              
                                    
     (parser location p notes)                                             
                                    
     (ly:pitch? ly:music?)
   #{
  \relative #p  #notes

   #})
