That's definitely going into the right direction - many thanks. I tried this:


    \new Staff <<
      {
        c'4 d'4 e'4 f'4
      }
      {
        \applyContext
          #(lambda (context)
            (make-music
              'SkipEvent
              'articulations
                (list (make-music
                  'AbsoluteDynamicEvent
                  'text
                  "ff"))
              'duration
                (ly:make-duration 0 0 1 (cdr (ly:context-property
                  context
                  'timeSignatureFraction)))))
      }
    >>


which is apparently valid, but the created skip event is not inserted into the 
music (which your reply already suggested).  I guess the problem boils down to 
how to get hold of the context without \applyContext.
