Re: scheme function for staccato

[Mats Bengtsson]

It seems that the articulation event has to be added after the note 
event in order not to confuse
\relative. The following modification of Reinhold's code seems to work 
better.

% To modify a sequence of notes, it's easiest to use a filter:
#(define (addStaccatoFilterFunction event)
 (let ( (eventname (ly:music-property  event 'name)) )
   (if (eq? eventname 'EventChord)
     (let ( (elements (ly:music-property event 'elements)) )
       ; don't add staccato to rests!
       (if (not (eq? (ly:music-property (car elements) 'name) 'RestEvent))
         (set! (ly:music-property event 'elements)
           (append elements (list (make-music 'ArticulationEvent 
'articulation-type "staccato"))
           ))))))
)

addStaccato = #(define-music-function (parser location music) (ly:music?)
  (music-filter addStaccatoFilterFunction music)
)


For some reason it also works if you use Reinhold's code with
\addStaccato { \relative { ... }}
instead of
\relative { \addStaccato {...}}
