+To typeset parallel pieces of music that have the same rhythm, they
+can be combined into a single @code{Voice} context, thus forming
+chords. To achieve this, enclose them in a simultaneous music
+construction:
+
+@lilypond[quote,relative=2,verbatim]

+@end lilypond
+
+This method leads to strange beamings and warnings if the pieces of
+music do not have the same rhythm. To typeset multiple, truly
+independent voices in a single staff, the @code{<<@{...@} \\
+@{...@}>>} construction is used, where the two (or more) voices are
+separated by double backslashes.
+
+@lilypond[quote,relative=3,verbatim]
+<<
+ { r8 r16 g e8. f16 g8[ c,] f e16 d }
+ \\
+ { d16 c d8~ d16 b c8~ c16 b c8~ c16 b8. }
+>>
+@end lilypond
+
+First and third voices get stems up, second and fourth voices get
+stems down, third and fourth voice noteheads are horizontally shifted,
+and rests move to avoid collisions. In the following example, the
+intermediate voice has stems up, therefore we enter it in the third
+place, so it becomes voice three which has the stems up as desired.
+
+@lilypond[quote,relative=3,verbatim]
+<<
+ { r8 g g g g f16 es f8 d }
+ \\
+ { es,8 r es r d r d r }

+ { d'8 s c s bes s a s }

+
+Spacing rests are often used to avoid too many rests, as seen in the
+example above.
+
+The method exposed creates two new voices when the @code{<<@{...@} \\
+@{...@}>>} construction is found in the code; to temporally add only
+one additional voice to an existing one, it is necessary to
+instantiate that voice explicitly. For these purposes, the
+@code{\voiceOne} ... @code{\voiceFour}, and @code{\oneVoice} commands
+can be used:
+
+@example
+<< @{ \voiceOne ... @} \new Voice @{ \voiceTwo ... @} >> \oneVoice
+@end example
+
+This is a better construction to keep the control of the voices, for
+example, to ease a consistent assign of lyrics to the proper voice
+context.

@knownissues
When using @code{merge-differently-headed} with an upstem eighth
half note head symbol.
@c investigate! Sometimes it works, sometimes not. --FV
-It is not clear in which circumpstances you can succesfully merge
-different note heads that are at the same time differently dotted.
+The requirements for successfully merging different note heads that
+are at the same time differently dotted are not clear.
There is no support for chords where the same note occurs with
different accidentals in the same chord. In this case, it is
recommended to use enharmonic transcription, or to use special
cluster notation (see @ref{Clusters}).
