-@cindex voices, more -- on a staff
-When different melodic lines are combined on a single staff they are
-printed as polyphonic voices; each voice has its own stems, slurs and
-beams, and the top voice has the stems up, while the bottom voice has
-them down.
-
-Entering such parts is done by entering each voice as a sequence (with
-@code{@{...@}}), and combining these simultaneously, separating the
-voices with @code{\\}

-<< { a4 g2 f4~ f4 } \\
- { r4 g4 f2 f4 } >>
-@end lilypond
-
-For polyphonic music typesetting, spacer rests can also be convenient;
-these are rests that do not print. They are useful for filling up
-voices that temporarily do not play. Here is the same example with a
-spacer rest (@samp{s}) instead of a normal rest (@samp{r}),
-
-@lilypond[quote,verbatim,relative=2,fragment]
-<< { a4 g2 f4~ f4 } \\
- { s4 g4 f2 f4 } >>
-@end lilypond
-
-@noindent
-Again, these expressions can be nested arbitrarily
-
-@lilypond[quote,fragment,verbatim,relative=2,fragment]
-<<
- \new Staff <<
- { a4 g2 f4~ f4 } \\
- { s4 g4 f2 f4 }
- >>
- \new Staff <<
- \clef bass
- { <c g>1 ~ <c g>4 } \\
- { e,,4 d e2 ~ e4}
- >>

-More features of polyphonic typesetting are described in this manual

-Piano music is typeset in two staves connected by a brace. Printing
-such a staff is similar to the polyphonic example in @ref{More staves},
-
-@example
-<< \new Staff @{ @dots{} @}
- \new Staff @{ @dots{} @} >>
-@end example
-
-@noindent
-but now this entire expression must be interpreted as a
-@code{PianoStaff}
-
-@example
-\new PianoStaff << \new Staff @dots{} >>
-@end example
-
-Here is a small example
-
-@lilypond[quote,verbatim,relative=1,fragment]
-\new PianoStaff <<
- \new Staff { \time 2/4 c4 c g' g }
- \new Staff { \clef bass c,, c' e c }
->>
