A variety of symbols can appear above and below notes to indicate
different characteristics of the performance.  They are added to a
note by adding a dash and the character signifying the
articulation.

See @ref{List of articulations}.

The meanings of these shorthands can be changed.  See
@file{ly/@/script@/-init@/.ly} for examples.

The script is automatically placed, but the direction can be
forced as well.  Like other pieces of LilyPond code, @code{_} will
place them below the staff, and @code{^} will place them above.

@lilypond[quote,ragged-right,fragment,verbatim]

Other symbols can be added using the syntax
@var{note}@code{\}@var{name}.  Again, they
can be forced up or down using @code{^} and @code{_},
e.g.,

@commonprop

The vertical ordering of scripts is controlled with the
@code{script-priority} property.  The lower this number, the
closer it will be put to the note.  In this example, the
@internalsref{TextScript} (the sharp symbol) first has the lowest
priority, so it is put lowest in the first example.  In the
second, the prall trill (the @internalsref{Script}) has the
lowest, so it is on the inside.  When two objects have the same
priority, the order in which they are entered decides which one
comes first.

@lilypond[verbatim,relative=3,ragged-right,fragment,quote]

A crescendo mark is started with @code{\<} and terminated with
@code{\!} or an absolute dynamic.  A decrescendo is started with
@code{\>} and is also terminated with @code{\!} or an absolute
dynamic.  @code{\cr} and @code{\decr} may be used instead of
@code{\<} and @code{\>}.  Because these marks are bound to notes,
you must use spacer notes if multiple marks are needed during one
note

@end lilypond

@noindent
A hairpin normally starts at the left edge of the beginning note
and ends on the right edge of the ending note.  If the ending note
falls on the downbeat, the hairpin ends on the immediately
preceding barline.  This may be modified by setting the
@code{hairpinToBarline} property,

@lilypond[quote,ragged-right,fragment,verbatim,relative=2]
\set hairpinToBarline = ##f
c4\< c2. c4\!
@end lilypond

In some situations the @code{\espressivo} articulation mark may be
suitable to indicate a crescendo and decrescendo on the one note,

@lilypond[quote,ragged-right,fragment,verbatim,relative=2]
c2 b4 a g1\espressivo
@end lilypond

This may give rise to very short hairpins.  Use
@code{minimum-length} in
@internalsref{Voice}.@internalsref{Hairpin} to lengthen them, for
example

@example
\override Voice.Hairpin #'minimum-length = #5
@end example

@cindex al niente
@cindex niente, al

Hairpins may be printed with a circled tip (al niente notation) by
setting the @code{circled-tip} property,

@lilypond[quote,ragged-right,fragment,relative=2,verbatim]
\override Hairpin #'circled-tip = ##t
c2\< c\!
c4\> c\< c2\!
@end lilypond


@cindex crescendo
@cindex decrescendo
@cindex diminuendo

You can also use text saying @emph{cresc.} instead of hairpins

@lilypond[quote,ragged-right,fragment,relative=2,verbatim]
\setTextCresc
c\< d e f\!
\setHairpinCresc
e\> d c b\!
\setTextDecresc

@lilypond[quote,ragged-right,fragment,relative=1,verbatim]
\set crescendoText = \markup { \italic "cresc. poco" }
\set crescendoSpanner = #'dashed-line
a'2\< a a a\!\mf
@end lilypond

To create new dynamic marks or text that should be aligned with
dynamics, see @ref{New dynamic marks}.

Vertical positioning of dynamics is handled by
@internalsref{DynamicLineSpanner}.


@commonprop

Dynamics that occur at, begin on, or end on, the same note will be
vertically aligned.  If you want to ensure that dynamics are
aligned when they do not occur on the same note, you can increase
the @code{staff-padding} property.

@example
\override DynamicLineSpanner #'staff-padding = #4
@end example

You may also use this property if the dynamics are colliding with
other notation.

Crescendi and decrescendi that end on the first note of a new line
are not printed.  To change this behavior, use

@example
\override Score.Hairpin #'after-line-breaking = ##t
@end example

Text style dynamic changes (such as @emph{cresc.} and @emph{dim.})
are printed with a dashed line showing their extent.  To surpress
printing this line, use

@example
\override DynamicTextSpanner #'dash-period = #-1.0
@end example

@node Ties
@unnumberedsubsubsec Ties

@cindex tie
@funindex ~

A tie connects two adjacent note heads of the same pitch.  The tie
in effect extends the length of a note.  Ties should not be
confused with slurs, which indicate articulation, or phrasing
slurs, which indicate musical phrasing.  A tie is entered using
the tilde symbol @samp{~}

@lilypond[quote,ragged-right,fragment,verbatim]
e' ~ e' <c' e' g'> ~ <c' e' g'>
@end lilypond

When a tie is applied to a chord, all note heads whose pitches
match are connected.  When no note heads match, no ties will be
created.  Chords may be partially tied by placing the tie inside
the chord,

@lilypond[quote,ragged-right,fragment,verbatim,relative=1]
<c~ e g~ b> <c e g b>
@end lilypond

A tie is just a way of extending a note duration, similar to the
augmentation dot.  The following example shows two ways of
notating exactly the same concept

@lilypond[quote,fragment,ragged-right]
\time 3/4 c'2. c'2 ~ c'4
@end lilypond

@noindent
Ties are used either when the note crosses a bar line, or when
dots cannot be used to denote the rhythm.  When using ties, larger
note values should be aligned to subdivisions of the measure, such
as

@lilypond[fragment,quote,ragged-right]
\relative {
  r8 c8 ~ c2 r4 | r8^"not" c2 ~ c8 r4
}
@end lilypond

If you need to tie a lot of notes over bars, it may be easier to
use automatic note splitting (see @ref{Automatic note splitting}).
This mechanism automatically splits long notes, and ties them
across bar lines.

@funindex \repeatTie

When a second alternative of a repeat starts with a tied note, you
have to repeat the tie.  This can be achieved with
@code{\repeatTie},

@lilypond[fragment,quote,ragged-right,relative=2]
r <c e g>\repeatTie
@end lilypond

@cindex repeating ties
@cindex volta brackets and ties

@commonprop

Ties are sometimes used to write out arpeggios.  In this case, two
tied notes need not be consecutive.  This can be achieved by
setting the @code{tieWaitForNote} property to true.  The same
feature is also useful, for example, to tie a tremolo to a chord.
For example,

@lilypond[fragment,verbatim,relative=1,ragged-right,quote]
\set tieWaitForNote = ##t
\grace { c16[~ e~ g]~ } <c, e g>2
\repeat tremolo 8 { c32~ c'~ } <c c,>1
e8~ c~ a~ f~ <e' c a f>2
@end lilypond

Ties may be engraved manually by changing the
@code{tie-configuration} property.  The first number indicates the
distance from the center of the staff in staff-spaces, and the
second number indicates the direction (1=up, -1=down).

@lilypond[fragment,verbatim,relative=1,ragged-right,quote]
<c e g>2~ <c e g> |
\override TieColumn #'tie-configuration =
  #'((0.0 . 1) (-2.0 . 1) (-4.0 . 1))

@refbugs

Switching staves when a tie is active will not produce a slanted
tie.

Changing clefs or octavations during a tie is not really
well-defined.  In these cases, a slur may be preferable.


@node Slurs
@unnumberedsubsubsec Slurs

@cindex Slurs

A slur indicates that notes are to be played bound or
@emph{legato}.  They are entered using parentheses

@lilypond[quote,ragged-right,relative=2,fragment,verbatim]
f( g a) a8 b( a4 g2 f4)
<c e>2( <b d>2)
@end lilypond

The direction of a slur can be specified with
@code{\slur@emph{DIR}}, where @code{@emph{DIR}} is either
@code{Up}, @code{Down}, or @code{Neutral} (automatically
selected).

However, there is a convenient shorthand for forcing slur
directions.  By adding @code{_} or @code{^} before the opening
parentheses, the direction is also set.  For example,

@lilypond[relative=2,ragged-right,quote,verbatim,fragment]
c4_( c) c^( c)
@end lilypond

Only one slur can be printed at once.  If you need to print a long
slur over a few small slurs, please see @ref{Phrasing slurs}.


@commonprop

Some composers write two slurs when they want legato chords.  This
can be achieved in LilyPond by setting @code{doubleSlurs},

@lilypond[verbatim,ragged-right,relative,fragment,quote]
\set doubleSlurs = ##t
<c e>4 ( <d f> <c e> <d f> )
@end lilypond

@node Phrasing slurs
@unnumberedsubsubsec Phrasing slurs

@cindex phrasing slurs
@cindex phrasing marks

A phrasing slur (or phrasing mark) connects notes and is used to
indicate a musical sentence.  It is written using @code{\(} and
@code{\)} respectively

@lilypond[quote,ragged-right,fragment,verbatim,relative=1]
\time 6/4 c'\( d( e) f( e) d\)
@end lilypond

Typographically, the phrasing slur behaves almost exactly like a
normal slur.  However, they are treated as different objects.  A
@code{\slurUp} will have no effect on a phrasing slur; instead,
use @code{\phrasingSlurUp}, @code{\phrasingSlurDown}, and
@code{\phrasingSlurNeutral}.

You cannot have simultaneous phrasing slurs.
