+The value of the property (here: @code{"lala"}) should be the name
+of a @code{Voice} context. For technical reasons, the @code{\set}
+command must be placed one syllable before the one to which the
+change in voice is to apply.
+
+Here is an example demonstrating its use:
+
+@lilypond[quote,ragged-right,verbatim]
+<<
+ \new Staff <<
+ \time 2/4
+ \new Voice = "one" \relative c'' {
+ \voiceOne
+ c4 b8. a16 g4. r8 a4 ( b ) c2
+ }
+ \new Voice = "two" \relative c' {
+ \voiceTwo
+ s2 s4. f8 e8 d4. c2
+ }
+ >>
+% takes durations and alignment from notes in "one" initially
+% then switches to "two"
+ \new Lyrics \lyricsto "one" {
+ No more let
+ \set associatedVoice = "two" % must be set one syllable early
+ sins and sor -- rows grow.
+ }
+>>
+@end lilypond

+
+In some complex vocal music, it may be desirable to place lyrics
+completely independently of notes. In this case do not use
+@code{\lyricsto} or @code{\addlyrics} and do not set
+@code{associatedVoice}. Syllables are entered like notes --
+but with pitches replaced by text -- and the duration of each
+syllable is entered explicitly after the syllable.
