this is coming from


        (define-public (major-key pitch-list)
          "Characterise the key as major if the alteration of the 
        third scale note is the same as that of the main note.
        Note: MIDI cannot handle other tonalities than major/minor.
        "
          ;; This charactersition is only true for a scale that starts at `c'.
          (if (not (equal? (car pitch-list) '(0 . 0)))
              (begin
                (ly:warn "Attempt to determine tonality of transposed scale")
                #t)
              (eq? (cdr (list-ref pitch-list 4)) (cdr (list-ref pitch-list 6))))
          )

This an algorithm which seems completely bogus to me. I think we
should scrap it. How about simply outputting everything as a major scale?
