Me not being a scheme professional by any means, nevertheless try:

#(define (hyphen? mus) (music-is-of-type? mus 'hyphen-event))
#(define (lyric? mus) (music-is-of-type? mus 'lyric-event))

#(display (map
           (lambda (j) (if (lyric? j)
                           (any hyphen? (ly:music-property j 
'articulations))))
           (ly:music-property words_one 'elements)))

*Question to the acutal experts:* In some snippets I found on the 
user-list, there are constructions like:

#(define (name-of music)
   (ly:music-property music 'name))

#(define (lyric? music)
   (eq? (name-of music) 'LyricEvent))

in contrast to my above definition of "lyric?" using music-is-of-type?.

1) Which variant is to be preferred?
2) What is the difference between 'LyricEvent and 'lyric-event ?
