Re: Writing score definition in Scheme

[Jan-Peter Voigt]

OK
here's a short hint created with the help of displayMusic:

% a dummy definition of create-staff
#(define (get-staff what)
   (make-music 'ContextSpeccedMusic
     'create-new #t
     'property-operations '()
     'context-type 'Staff
     'element #{ c''4 #}))

% a scheme representation of \new StaffGroup
$(make-music
  'ContextSpeccedMusic
  'create-new #t
  'property-operations '()
  'context-type 'StaffGroup
  'element (make-music
            'SimultaneousMusic
            'elements (map get-staff '(oboe flute))))
