-Keyboard instruments are usually notated with Piano staves. These are
-two or more normal staves coupled with a brace. The same notation is
-also used for harps and other keyed instruments. Organ music is normally
-written with two staves inside a @code{PianoStaff} group and third,
-normal staff for the pedals.

@node Changing staff manually
@subsubsection Changing staff manually
@funindex \change
Voices can be switched between staves manually, using the command
+
@example
\change Staff = @var{staffname}
@end example
@noindent
-The string @var{staffname} is the name of the staff. It switches the
-current voice from its current staff to the Staff called
-@var{staffname}. Typical values for @var{staffname} are @code{"up"}
-and @code{"down"}, or @code{"RH"} and @code{"LH"}.

Cross-staff notes are beamed automatically:

-of the staff that is closest to the beam. For a simple example of beam
