+1 but music-map will not show the tied event, because music-map doesn't care  
of 'articulation property (in my memory, in the past, it does). So you have to 
make it by hand.

%%%%%%%
\version "2.18.2"
#(define (name-of music) (display-scheme-music (ly:music-property music 
'name)))

#(define (show-names music)
(let ((elts (ly:music-property music 'elements))
      (elt (ly:music-property music 'elements))
      (arti (ly:music-property music 'articulations)))
  (name-of music)
  (if (ly:music? elt) (show-names elt))
  (if (pair? elts)(map show-names elts))  
  (if (pair? arti) (map show-names arti))
  music))
  
musNam = #(define-music-function (parser location myx ) (ly:music?)
(show-names myx))
            
music = {c ~ c}
\musNam #music
%%%%%%%

NB
Reading "music-function.scm", you can see that music-filter does care of  
'articulation property, but i don't really understand why music-map doesn't.
