+In some instances of complex polyphonic music, you may need additional
+voices to avoid collisions between notes. Additional voices are added
+by defining an identifier, as shown below:

+voiceFive = #(context-spec-music (make-voice-props-set 4) 'Voice)

Normally, note heads with a different number of dots are not merged, but
when the object property @code{merge-differently-dotted} is set in
-the @internalsref{NoteCollision} object, they are merged
+the @internalsref{NoteCollision} object, they are merged:
+
@lilypond[quote,verbatim,fragment,ragged-right,relative=2]
\new Voice << {
g8 g8
@end lilypond
Similarly, you can merge half note heads with eighth notes, by setting
-@code{merge-differently-headed}
+@code{merge-differently-headed}:
+
@lilypond[quote,ragged-right,fragment,relative=2,verbatim]
\new Voice << {
c8 c4.
\new Voice << c''4 \\ r4 >>
@end lilypond
+If three or more notes line up in the same column,
+@code{merge-differently-headed} cannot
+successfully complete the merge of the two notes that should be merged.
+To allow the merge to work properly, apply a @code{\shift} to the note that
+should not be merged. In the first measure of following example,
+@code{merge-differently-headed} does not work (the half-note head is
+solid). In the second measure, @code{\shiftOn} is applied to move the
+top @code{g} out of the column, and @code{merge-differently-headed}
+works properly.
