+@notation{Staves} (singular: @notation{staff}) are created with
+the @code{\new} or @code{\context} commands. For details, see
+@ref{Creating contexts}.
+
+The basic staff context is @code{Staff}:
+
+@lilypond[verbatim,quote,relative=2]
+\new Staff { c4 d e f }
+@end lilypond
+
+The @code{DrumStaff} context creates a five-line staff set up for
+a typical drum set. Each instrument is shown with a different
+symbol. The instruments are entered in drum mode following a
+@code{\drummode} command, with each instrument specified by name.
+For details, see @ref{Percussion staves}.
+
+@lilypond[verbatim,quote]
+\new DrumStaff {
+ \drummode { cymc hh ss tomh }
+}
+@end lilypond
+
+@code{RhythmicStaff} creates a single-line staff that only
+displays the rhythmic values of the input. Real durations are
+preserved. For details, see @ref{Showing melody rhythms}.
+
+@lilypond[verbatim,quote,relative=2]
+\new RhythmicStaff { c4 d e f }
+@end lilypond
+
+@code{TabStaff} creates a tablature with six strings in standard
+guitar tuning. For details, see @ref{Default tablatures}.
+
+@lilypond[verbatim,quote,relative=2]
+\new TabStaff { c4 d e f }
+@end lilypond
+
+There are two staff contexts specific for the notation of ancient
+music: @code{MensuralStaff} and @code{VaticanaStaff}. They are
+described in @ref{Pre-defined contexts}.
+
+The @code{GregorianTranscriptionStaff} context creates a staff to
+notate modern Gregorian chant. It does not show bar lines.
+
+@lilypond[verbatim,quote,relative=2]

+The lines of a staff belong to the @code{StaffSymbol} grob.
+@code{StaffSymbol} properties can be modified to change the
+appearance of a staff, but they must be modified before the staff
+is created.
+
+The number of staff lines may be changed. The clef position and
+the position of middle C may need to be modified to fit the new
+staff. For an explanation, refer to the snippet section in
+@ref{Clef}.
+
+@lilypond[verbatim,quote,relative=2]
+\new Staff \with {
+ \override StaffSymbol #'line-count = #3
+}
+{ d4 d d d }
+@end lilypond
+
+Staff line thickness can be modified. The thickness of ledger
+lines and stems are also affected, since they depend on staff line
+thickness.
+
+@lilypond[verbatim,quote,relative=1]
+\new Staff \with {
+ \override StaffSymbol #'thickness = #3
+}
+{ e4 d c b }
+@end lilypond
+
+Ledger line thickness can be set independently of staff line
+thickness. In the example the two numbers are factors multiplying
+the staff line thickness and the staff line spacing. The two
+contributions are added to give the ledger line thickness.
+
+@lilypond[verbatim,quote,relative=1]
+\new Staff \with {
+ \override StaffSymbol #'ledger-line-thickness = #'(1 . 0.2)
+}
+{ e4 d c b }

+The distance between staff lines can be changed. This setting
+affects the spacing of ledger lines as well.

+@notation{Ossia} staves can be set by creating a new simultaneous

+

+\new Staff \relative c'' {
+ c4 b d c
+ <<
+ { c4 b d c }
+ \new Staff { e4 d f e }
+ >>
+ c4 b c2
+}
+@end lilypond
+
+@noindent
+However, the above example is not what is usually desired. To
+create ossia staves that are above the original staff, have no
+time signature or clef, and have a smaller font size, tweaks must
+be used. The Learning Manual describes a specific technique to
+achieve this goal, beginning with
+@rlearning{Nesting music expressions}.
+
+The following example uses the @code{alignAboveContext} property
+to align the ossia staff. This method is most appropriate when
+only a few ossia staves are needed.
+
+@lilypond[verbatim,quote]
+\new Staff = main \relative c'' {
+ c4 b d c
+ <<
+ { c4 b d c }
+
+ \new Staff \with {
+ \remove "Time_signature_engraver"
+ alignAboveContext = #"main"

+ \override StaffSymbol #'staff-space = #(magstep -3)
+ \override StaffSymbol #'thickness = #(magstep -3)
+ firstClef = ##f
+ }
+ { e4 d f e }
+ >>
+ c4 b c2
+}
+@end lilypond
+
+If many isolated ossia staves are needed, creating an empty
+@code{Staff} context with a specific @emph{context id} may be more
+appropriate; the ossia staves may then be created by
+@emph{calling} this context and using @code{\startStaff} and
+@code{\stopStaff} at the desired locations. The benefits of this
+method are more apparent if the piece is longer than the following
+example.
+
+@lilypond[verbatim,quote,ragged-right]
+<<
+ \new Staff = ossia \with {
+ \remove "Time_signature_engraver"
+ \override Clef #'transparent = ##t

+@end lilypond
+
+
+Using the @code{\Staff \RemoveEmptyStaves} command to create ossia

+convenient when ossia staves occur immediately following a line
+break. For more information about
+@code{\Staff \RemoveEmptyStaves}, see @ref{Hiding staves}.

+It is very common for one voice to use the same notes as those from
+another voice. For example, first and second violins playing the same
+phrase during a particular passage of the music. This is done by
+letting one voice @emph{quote} the other, without having to re-enter the
+music all over again for the second voice.
+
+The @code{\addQuote} command, used in the top level scope, defines a
+stream of music from which fragments can be quoted.
+
+The @code{\quoteDuring} command is used to indicate the point where the
+quotation begins. It is followed by two arguments: the name of the
+quoted voice, as defined with @code{\addQuote}, and a music expression
+for the duration of the quote.

+Only the contents of the first @code{Voice} occurring in an
+@code{\addQuote} command will be considered for quotation, so
+@code{@var{music}} cannot contain @code{\new} and
+@code{\context Voice} statements that would switch to a different
+Voice.
+
+Quoting grace notes is broken and can even cause LilyPond to
+crash.
+
+Quoting nested triplets may result in poor notation.

+
+The simplest way to format cue notes is to explicitly create a
+@code{CueVoice} context within the part.
+
+@lilypond[verbatim,relative=1]
+R1
+<<
+ { e2\rest r4. e8 }
+ \new CueVoice {
+ \stemUp d'8^"flute" c d e fis2
+ }
+>>
+d,4 r a r
+@end lilypond
+
+The @code{\cueClef} command can also be used with an explict
+@code{CueVoice} context if a change of clef is required and will print
+an appropriately sized clef for the cue notes. The @code{\cueClefUnset}
+command can then be used to switch back to the original clef, again with
+an appropriately sized clef.
+
+@lilypond[verbatim,noragged-right,relative=1]
+\clef "bass"
+R1
+<<
+ { e2\rest r4. \cueClefUnset e,8 }
+ \new CueVoice {
+ \cueClef "treble" \stemUp d''8^"flute" c d e fis2
+ }
+>>
+d,,4 r a r
+@end lilypond
+
+The @code{\cueClef} and @code{\cueClefUnset} command can also be used
+without a @code{CueVoice} if required.
+
+@lilypond[verbatim,noragged-right,relative=1]
+\clef "bass"
+R1
+\cueClef "treble"
+d'8^"flute" c d e fis2
+\cueClefUnset
+d,,4 r a r
+@end lilypond
+
+For more complex cue note placement, e.g including transposition, or
+inserting cue notes from multiple music sources the @code{\cueDuring} or
+@code{\cueDuringWithClef} commands can be used. These are more
+specialized form of @code{\quoteDuring}, see @ref{Quoting other voices}
+in the previous section.
+
+The syntax is:
+
+@example
+\cueDuring #@var{quotename} #@var{direction} #@var{music}
+@end example
+
+and
+
+@example
+\cueDuringWithClef #@var{quotename} #@var{direction} #@var{clef} #@var{music}
+@end example
+
+The music from the corresponding measures of the @code{@var{quote name}}
+is added as @code{CueVoice} context and occurs simultaneously with the
+@code{@var{music}}, which creates a polyphonic situation. The
+@code{@var{direction}} takes the argument @code{UP} or @code{DOWN}, and
+corresponds to first and second voices respectively determining how
+the cue notes are printed in relation to the other voice.

+In the above example, the @code{Voice} context had to be
+explicitly declared, or else the entire music expression would
+belong to the @code{CueVoice} context.
+
+It is possible to adjust which aspects of the music are quoted with
+@code{\cueDuring} by setting the @code{quotedCueEventTypes}
+property. Its default value is @code{#'(note-event rest-event
+tie-event beam-event tuplet-span-event)}, which means that only
+notes, rests, ties, beams and tuplets are quoted, but not
+articulations, dynamic marks, markup etc.

+@end lilypond
+
+Markup can be used to show the name of the quoted instrument. Also,

+be restored at the end of the cue notes.
