+Two variants of @code{\lyricmode} additionally set an associated
+context used to synchronise the lyric syllables to music. The more
+convenient @code{\addlyrics} immediately follows the musical content
+of the Voice context with which it should be synchronised, implicitly
+creating a Lyrics context of its own. The more versatile
+@code{\lyricsto} requires both specifying the associated Voice context
+by name and explicitly creating a containing Lyrics context. For
+details see @ref{Automatic syllable durations}.
