Looking at the code, it appears that, for a lyrics event, the 'name
property of the music object will be 'LyricEvent whereas 'lyric-event
will be one of its 'types:
(LyricEvent
. ((description . "A lyric syllable. Must be entered in lyrics mode,
i.e., @code{\\lyrics @{ twinkle4 twinkle4 @} }.")
(iterator-ctor . ,ly:rhythmic-music-iterator::constructor)
(types . (rhythmic-event lyric-event event))
))
The music-is-of-type function checks the 'types list, so you would need
to check for 'lyric-event. If you are using ly:music-property, then you
would need to check the 'name for 'LyricEvent. It looks like 'LyricEvent
is the only class that includes lyric-event in its 'types, so as long as
that is true the two checks are equivalent (as far as I can tell).
