A variety of symbols that denote articulations, ornamentations,
and other performance indications can be attached to a note using
this syntax:

@example
@var{note}\@var{name}
@end example

The possible values for @var{name} are listed in @ref{List of
articulations}.  For example:

@lilypond[verbatim,quote,relative=2]
c4\staccato c\mordent b2\turn
c1\fermata
@end lilypond

@cindex marcato
@cindex stopped
@cindex tenuto
@cindex staccatissimo
@cindex accent
@cindex staccato
@cindex portato

Some of these articulations have shorthands for easier entry.
Shorthands are appended to the note name, and their syntax
consists of a dash (@tie{}@code{-}) followed by a symbol
signifying the articulation.  Predefined shorthands exist for
@notation{marcato}, @notation{stopped}, @notation{tenuto},
@notation{staccatissimo}, @notation{accent}, @notation{staccato},
and @notation{portato}.  Their corresponding output appears as
follows:

@lilypond[verbatim,quote,relative=2]
c4-^  c-+  c--  c-|
c4->  c-.  c-_
@end lilypond

The rules for the default placement of articulations are defined
in @file{scm/@/script@/.scm}.  Articulations and ornamentations
may be manually placed above or below the staff, see
@ref{Direction and placement}.

@code{\ppppp}, @code{\pppp}, @code{\ppp}, @code{\pp}, @code{\p},
@code{\mp}, @code{\mf}, @code{\f}, @code{\ff}, @code{\fff},
@code{\ffff}, @code{\fp}, @code{\sf}, @code{\sff}, @code{\sp},

A @notation{crescendo} mark is started with @code{\<} and
terminated with @code{\!}, an absolute dynamic, or an additional
crescendo or decrescendo mark.  A @notation{decrescendo} mark is
started with @code{\>} and is also terminated with @code{\!}, an
absolute dynamic, or another crescendo or decrescendo mark.
@code{\cr} and @code{\decr} may be used instead of @code{\<} and
@code{\>}.  @notation{Hairpins} are engraved by default using this
notation.

@lilypond[verbatim,quote,relative=2]

Spacer rests are needed to engrave multiple marks on one note.

@lilypond[verbatim,quote,relative=2]
c4\< c\! d\> e\!
<< f1 { s4 s4\< s4\> s4\! } >>
@end lilypond

@cindex espressivo articulation

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

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

@cindex crescendo
@cindex decrescendo
@cindex diminuendo

Crescendos and decrescendos can be engraved as textual markings
instead of hairpins.  The built-in commands that enable these text
modes are @code{\setTextCresc}, @code{\setTextDecresc},
@code{\setTextDecr}, and @code{\setTextDim}.  The corresponding
@code{\setHairpinCresc}, @code{\setHairpinDim}, and
@code{\setHairpinDecresc} commands will revert to hairpins again:

@lilypond[verbatim,quote,relative=2]
c4\< d e f\!
e4\> d c b\!
\setTextCresc
c4\< d e f\!
\setTextDecresc
e4\> d c b\!
\setHairpinCresc
c4\< d e f\!
@end lilypond

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

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

@node New dynamic marks
@unnumberedsubsubsec New dynamic marks

@cindex new dynamic marks
@cindex dynamic marks, new

The easiest way to create dynamic indications is to use
@code{\markup} objects.

@lilypond[verbatim,quote]
moltoF = \markup { molto \dynamic f }

\relative c' {
  <d e>16 <d e>
  <d e>2.._\moltoF
}
@end lilypond

@cindex dynamics, editorial
@cindex dynamics, parenthesis

Markup mode makes possible, for instance, to add
editorial dynamics, printed in round parenthesis or square
brackets.  Its syntax is described in @ref{Formatting text}.

@lilypond[verbatim,quote]
roundf = \markup { \center-align { \line { \bold { \italic ( }
         \dynamic f \bold { \italic ) } } } }
boxf = \markup { \bracket { \dynamic f } }
\relative c' {
  c1_\roundf
  c1_\boxf
}
@end lilypond

Markup objects are treated differently from authentic dynamic marks.
Defining dynamic objects that will be entered and printed exactly like
standard dynamic marks is also possible, using the following function:

@cindex make-dynamic-script

@lilypond[verbatim,quote]
sfzp = #(make-dynamic-script "sfzp")
\relative c' {
  c4 c c\sfzp c
}
@end lilypond

@noindent
Note that the dynamic font only contains the characters 
@code{f,m,p,r,s} and @code{z}.  To switch to other font families,
it is necessary to use markup mode in its Scheme form, as
explained in @ref{Markup construction in Scheme}.

@lilypond[verbatim,quote]
moltoF = #(make-dynamic-script (markup 
                      #:normal-text "molto"
                      #:dynamic "f"))
\relative c' {
  <d e>16 <d e>
  <d e>2..\moltoF
}
@end lilypond

@noindent
Font settings in markup mode are described in
@ref{Common markup commands}.

@notation{Slurs} are entered using parentheses:

@lilypond[verbatim,quote,relative=2]

Slurs can be solid, dotted, or dashed.  Solid is the default slur
style:

@lilypond[verbatim,quote,relative=2]

@end lilypond

Typographically, a 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.  Phrasing
slurs may be manually placed above or below the notes, see
@ref{Direction and placement}.

@lilypond[verbatim,quote,relative=1]

@node Arpeggio
@unnumberedsubsubsec Arpeggio

@cindex arpeggio
@cindex broken chord
@cindex chord, broken

An @notation{arpeggio} on a chord (also known as a broken chord)
is denoted by appending @code{\arpeggio} to the chord construct:

@lilypond[verbatim,quote,relative=1]
<c e g c>1\arpeggio
@end lilypond

The direction of an arpeggio is indicated by adding an arrowhead
to the wiggly line.  The commands @code{\arpeggioUp} and
@code{\arpeggioDown} are used for this task.
@code{\arpeggioNeutral} reverts back to an arrow-less arpeggio:

@lilypond[verbatim,quote,relative=1]
\arpeggioUp
<c e g c>2\arpeggio
\arpeggioDown
<c e g c>2\arpeggio
\arpeggioNeutral
<c e g c>1\arpeggio
@end lilypond

The command @code{\arpeggioBracket} can be used to create a square
bracket on the left of a chord, indicating that the chord should
@emph{not} be arpeggiated.  @code{\arpeggioNeutral} reverts back
to a regular arpeggio:

@lilypond[verbatim,quote,relative=1]
<c e g c>2
\arpeggioBracket
<c e g c>2\arpeggio
\arpeggioNeutral
<c e g c>1\arpeggio
@end lilypond

A @emph{parenthesis} style bracket may be attached to a chord
construct instead of a square bracket.

@c Maybe create a new \arpeggioParen command, or something
@c like that. -pm

Long running trills are made with @code{\startTrillSpan} and

trill is shown combined with grace notes.  To achieve precise
