This section explains how to include text (with various
formatting) in music scores.

@noindent
Some text elements that are not dealt with here are discussed in other
specific sections: @ref{Vocal music}, @ref{Titles and headers}.

@subsection Writing text

This section introduces different ways of adding text to a score.

@cindex Text, other languages
@warning{To write accented and special text (such as characters
from other languages), simply insert the characters directly into
the LilyPond file.  The file must be saved as UTF-8.  For more
information, see @ref{Text encoding}.}

@node Text scripts
@unnumberedsubsubsec Text scripts

@cindex Text scripts
@cindex text items, non-empty
@cindex non-empty texts
@cindex quoted text

Simple @qq{quoted text} indications may be added to a score, as
demonstrated in the following example.  Such indications may be
manually placed above or below the staff, using the syntax described
in @ref{Direction and placement}.

@lilypond[quote,verbatim,relative=2]
a8^"pizz." g f e a4-"scherz." f
@end lilypond

This syntax is actually a shorthand; more complex text
formatting may be added to a note by explicitly using a
@code{\markup} block, as described in @ref{Formatting text}.

@lilypond[quote,verbatim,relative=2]
a8^\markup { \italic pizz. } g f e
a4_\markup { \tiny scherz. \bold molto } f
@end lilypond

By default, text indications do not influence the note spacing.
However, their widths can be taken into account:
in the following example, the first text string does not affect
spacing, whereas the second one does.

@lilypond[quote,verbatim,relative=2]
a8^"pizz." g f e

@knownissues

Checking to make sure that text scripts and lyrics are within the
margins is a relatively large computational task.  To speed up
processing, LilyPond does not perform such calculations by
default; to enable it, use

@example
\override Score.PaperColumn #'keep-inside-line = ##t
@end example


@node Text spanners
@unnumberedsubsubsec Text spanners

@cindex text spanners

Some performance indications, e.g., @notation{rallentando} or
@notation{accelerando}, are written as text and are extended over
multiple notes with dotted lines.  Such objects, called @qq{spanners},
may be created from one note to another using the following syntax:

@lilypond[verbatim,quote,relative=2]
\override TextSpanner #'(bound-details left text) = "rit."
b1\startTextSpan
e,\stopTextSpan
@end lilypond

@cindex text spanners, formatting
@cindex formatting text spanners

@noindent
The string to be printed is set through object properties.  By default
it is printed in italic characters, but different formatting can be
obtained using @code{\markup} blocks, as described in @ref{Formatting
text}.

@lilypond[quote,relative=2,verbatim]
\override TextSpanner #'(bound-details left text) =
  \markup { \upright "rit." }
b1\startTextSpan c
e,\stopTextSpan
@end lilypond

The line style, as well as the text string, can be defined as an
object property.  This syntax is described in @ref{Line styles}.

Various text elements may be added to a score using

@c attached to an object like \markup is). -vv

@lilypond[verbatim,quote,relative=2]
c4
\mark "Allegro"
c c c
@end lilypond

This syntax makes it possible to put any text on a bar line;
more complex text formatting may be added using a @code{\markup}
block, as described in @ref{Formatting text}:

@lilypond[quote,verbatim,relative=1]
<c e>1
\mark \markup { \italic { colla parte } }
<d f>2 <e g>
<c f aes>1
@end lilypond

@noindent
This syntax also allows to print special signs, like coda, segno
or fermata, by specifying the appropriate symbol name as explained in
@ref{Music notation inside markup}:

@lilypond[quote,verbatim,relative=2]
<bes f>2 <aes d>
\mark \markup { \musicglyph #"scripts.ufermata" }
<e g>1
@end lilypond

@noindent
Such objects are only typeset above the top staff of the score; depending on
whether they are specified at the end or the middle of a bar, they
can be placed above the bar line or between notes.  When specified at a
line break, the mark will be printed at the beginning of the next line.

@lilypond[quote,verbatim,relative=2]

@cindex markup
@cindex text markup

@cindex typeset text

@funindex \markup
@funindex markup

A @code{\markup} block is used to typeset text with an extensible
syntax called @qq{markup mode}.

@cindex markup expressions
@cindex expressions, markup
@cindex markup syntax
@cindex synatax, markup

The markup syntax is similar to LilyPond's usual syntax: a
@code{\markup} expression is enclosed in curly braces @code{@{
@dots{} @}}.  A single word is regarded as a minimal expression,
and therefore does not need to be enclosed with braces.

Unlike simple @qq{quoted text} indications, @code{\markup} blocks may
contain nested expressions or markup commands, entered using the
backslash @code{\} character.  Such commands only affect the first
following expression.

@lilypond[quote,verbatim,relative=2]
a1-\markup intenso
a2^\markup { poco \italic più forte  }
c e1
d2_\markup { \italic "string. assai" }
e
b1^\markup { \bold { molto \italic  agitato } }
c
@end lilypond

@cindex special characters in markup mode
@cindex markup mode, special characters
@cindex reserved characters, printing
@cindex printing reserved characters
@cindex printing special characters
@cindex quoted text in markup mode
@cindex markup mode, quoted text

A @code{\markup} block may also contain quoted text strings.  Such
strings are treated as minimal text expressions, and therefore any
markup command or special character (such as @code{\} and @code{#})
will be printed verbatim without affecting the formatting of the text.
Double quotation marks themselves may be printed by preceding them
with backslashes.

@lilypond[quote,verbatim,relative=2]
a1^"\italic markup..."
a_\markup { \italic "... prints \"italic\" letters!" }
a a
@end lilypond

To be treated as a distinct expression, a list of words needs to be
enclosed with double quotes or preceded by a command.  The way markup
expressions are defined affects how these expressions will be stacked,
centered and aligned; in the following example, the second
@code{\markup} expression is treated the same as the first one:

@lilypond[quote,verbatim,relative=2]
c1^\markup { \center-column { a bbb c } }
c1^\markup { \center-column { a { bbb c } } }
c1^\markup { \center-column { a \line { bbb c } } }
c1^\markup { \center-column { a "bbb c" } }
@end lilypond

Markups can be stored in variables.  Such variables may be
directly attached to notes:

@lilypond[quote,verbatim]
allegro = \markup { \bold \large Allegro }

{
  d''8.^\allegro
  d'16 d'4 r2
}
@end lilypond


@noindent
An exhaustive list of @code{\markup}-specific commands can be found in
@ref{Text markup commands}.

@cindex switching fonts

@funindex \italic

Basic font switching is supported in markup mode:

@lilypond[quote,verbatim,relative=2]
d1^\markup {
  \bold { Più mosso }
  \italic { non troppo \underline Vivo }
}
r2 r4 r8

@cindex text size

@funindex \fontsize
@funindex fontsize

The size of the characters can also be altered in different ways:
@itemize
@item
the font size can be set to predefined standard sizes,

@item
the font size can be set to an absolute value,

@item
the font size can also be changed relatively to its previous value.
@end itemize

@noindent
The following example demonstrates these three methods:

@lilypond[quote,verbatim,relative=1]
f1_\markup {
  \tiny espressivo
  \large e
  \normalsize intenso
}
a^\markup {
  \fontsize #5 Sinfonia
  \fontsize #2 da

}
bes^\markup { (con
  \larger grande
  \smaller emozione
  \magnify #0.6 { e sentimento } )
}
d c2 r8 c bes a g1
@end lilypond

@cindex subscript
@cindex superscript

@funindex \super
@funindex super
@funindex \sub
@funindex sub

Text may be printed as subscript or superscript.  By default these are
printed in a smaller size, but a normal size can be used as well:

@lilypond[quote,verbatim]
\markup {
  \column {
    \line { 1 \super st movement }
    \line { 1 \normal-size-super st movement
      \sub { (part two) }  }
  }
}
@end lilypond

@cindex font families

The markup mode provides an easy way to select alternate font
families.  The default serif font, of roman type, is automatically
selected unless specified otherwise; on the last line of the following
example, there is no difference between the first and the second word.

@lilypond[quote,verbatim]
\markup {
  \column {
    \line { Act \number 1 }
    \line { \sans { Scene I. } }
    \line { \typewriter { Verona. An open place. } }
    \line { Enter \roman Valentine and Proteus. }
  }
}
@end lilypond

@noindent
Some of these font families, used for specific items such as numbers
or dynamics, do not provide all characters, as mentioned in @ref{New
dynamic marks} and @ref{Manual repeat marks}.

@c \concat is actually documented in Align (it is not
@c a font-switching command). But we need it here. -vv

When used inside a word, some font-switching or formatting commands
may produce an unwanted blank space.  This can easily be solved by
concatenating the text elements together:

@lilypond[quote,verbatim]
\markup {
  \column {
    \line {
      \concat { 1 \super st }
      movement
    }
    \line {
      \concat { \dynamic p , }
      \italic { con dolce espressione }
    }
  }
}
@end lilypond

An exhaustive list of font switching commands and custom font usage
commands can be found in @ref{Font}.

Defining custom font sets is also possible, as explained in
@ref{Fonts}.

This subsection discusses how to place text in markup mode.  Markup

@funindex \left-align
@funindex left-align
@funindex \center-align

@funindex \right-align

Markup objects may be aligned in different ways.  By default, a text
indication is aligned on its left edge: in the following example,
there is no difference between the first and the second markup.

@lilypond[quote,verbatim,relative=2]
d1-\markup { poco }
f
d-\markup { \left-align poco }
f
d-\markup { \center-align { poco } }
f
d-\markup { \right-align poco }
@end lilypond

@funindex \halign
@funindex halign

Horizontal alignment may be fine-tuned using a numeric value:

@lilypond[quote,verbatim,relative=2]
a1-\markup { \halign #-1 poco }
e'
a,-\markup { \halign #0 poco }
e'
a,-\markup { \halign #0.5 poco }
e'
a,-\markup { \halign #2 poco }
@end lilypond

@noindent
Some objects may have alignment procedures of their own, and therefore
are not affected by these commands.  It is possible to move such
markup objects as a whole, as shown for instance in @ref{Text marks}.

@cindex text, vertical alignment
@cindex vertical text alignment

@funindex \raise
@funindex raise
@funindex \lower
@funindex lower
@funindex \null
@funindex null

@c QUERY Should the function of ``\null'' be clarified? rp

Vertical alignment is a bit more complex.  As stated above, markup
objects can be moved as a whole; however, it is also possible to move
specific elements inside a markup block.  In this case, the element to
be moved needs to be preceded with an @emph{anchor point}, that can be
another markup element or an invisible object.  The following example
demonstrates these two possibilities; the last markup in this example
has no anchor point, and therefore is not moved.

@lilypond[quote,verbatim,relative=1]
d2^\markup {
  Acte I
  \raise #2 { Scène 1 }
}
a'
g_\markup {
  \null
  \lower #4 \bold { Très modéré }

}

@end lilypond

@funindex \general-align
@funindex general-align
@funindex \translate
@funindex translate
@funindex \translate-scaled
@funindex translate-scaled

Some commands can affect both the horizontal and vertical alignment of
text objects in markup mode.  Any object affected by these commands
must be preceded with an anchor point:

@lilypond[quote,verbatim,relative=1]
d2^\markup {
  Acte I
  \translate #'(-1 . 2) "Scène 1"
}
a'
g_\markup {
  \null
  \general-align #Y #3.2 \bold "Très modéré"

A markup object may include several lines of text.  In the following
example, each element or expression is placed on its own line, either
left-aligned or centered:

@lilypond[quote,verbatim]
\markup {
  \column {
    a
    "b c"
    \line { d e f }

  }
}
@end lilypond

Similarly, a list of elements or expressions may be spread to fill the
entire horizontal line width (if there is only one element, it will be
centered on the page).  These expressions can, in turn, include
multi-line text or any other markup expression:

@lilypond[quote,verbatim]
\markup {
  \fill-line {
    \line { William S. Gilbert }
    \center-column {
      \huge \smallCaps "The Mikado"
      or
      \smallCaps "The Town of Titipu"
    }

Long text indications can also be automatically wrapped accordingly to

as shown in the following example.

@lilypond[quote,verbatim]
\markup {

explicitely specify the size of the drawing, as demonstrated below:

  \combine
    \epsfile #X #10 #"./context-example.eps"
    \with-dimensions #'(0 . 6) #'(0 . 10)

@node Music notation inside markup
@unnumberedsubsubsec Music notation inside markup

@cindex notation inside markup
@cindex music inside markup
@cindex markup, music notation inside

Various musical notation elements may be added to a score, inside a
markup object.

Notes and accidentals can be entered using markup commands:

@lilypond[quote,verbatim,relative=2]
a2 a^\markup {
  \note #"4" #1
  =
  \note-by-number #1 #1 #1.5
}
b1_\markup {
  \natural \semiflat \flat
  \sesquiflat \doubleflat
}
\glissando
a1_\markup {
  \natural \semisharp \sharp
  \sesquisharp \doublesharp
}
\glissando b
@end lilypond

Other notation objects may also be printed
in markup mode:

@lilypond[quote,verbatim,relative=1]
g1 bes
ees-\markup {
  \finger 4
  \tied-lyric #"~"
  \finger 1
}
fis_\markup { \dynamic rf }
bes^\markup {
  \beam #8 #0.1 #0.5
}
cis
d-\markup {
  \markalphabet #8
  \markletter #8
}
@end lilypond

More generally, any available musical symbol may be included
separately in a markup object, as demonstrated below; an exhaustive
list of these symbols and their names can be found in @ref{The Feta
font}.

@lilypond[quote,verbatim,relative=2]
c2
c'^\markup { \musicglyph #"eight" }
c,4
c,8._\markup { \musicglyph #"clefs.G_change" }
c16
c2^\markup { \musicglyph #"timesig.neomensural94" }
@end lilypond

Another way of printing non-text glyphs is described in @ref{Fonts
explained}.  This is useful for printing braces of various sizes.

The markup mode also supports diagrams for specific
instruments:

@lilypond[quote,verbatim,relative=2]
c1^\markup {
  \fret-diagram-terse #"x;x;o;2;3;2;"
}
c^\markup {
  \harp-pedal #"^-v|--ov^"
}
c
c^\markup {
  \combine
    \musicglyph #"accordion.accDiscant"
    \combine
      \raise #0.5 \musicglyph #"accordion.accDot"
      \raise #1.5 \musicglyph #"accordion.accDot"
}
@end lilypond

@c The accordion diagram is actually taken from a snippet.

@noindent
Such diagrams are documented in @ref{Instrument Specific Markup}.

@cindex score inside markup
@cindex markup, score inside

A whole score can even be nested inside a markup object.  In such a
case, the nested @code{\score} block must contain a @code{\layout}
block, as demonstrated here:

@lilypond[quote,verbatim,relative=1]
c4 d^\markup {
  \score {
    \relative c' { c4 d e f }
    \layout { }
  }
}
e f |
c d e f

@funindex \justified-lines

@funindex \wordwrap-lines
@funindex wordwrap-lines

Although standard markup objects are not breakable, a specific syntax
makes it possible to enter lines of text that can spread over multiple
pages:

@lilypond[quote,verbatim]
\markuplines {
  \justified-lines {
    A very long text of justified lines.
    ...
  }
  \wordwrap-lines {
    Another very long paragraph.
    ...
  }
  ...
}
@end lilypond

This syntax accepts a list of markups, that can be
@itemize
@item
the result of a markup list command,
@item
a list of markups,
@item
a list of markup lists.
@end itemize

This section presents the way fonts are handled, and how they may be
changed in scores.

@cindex Pango
@cindex fonts, explained

@cindex fonts, non-text in markup
@cindex non-text fonts in markup

@funindex font-interface

Fonts are handled through several libraries.  FontConfig is used to
detect available fonts on the system; the selected fonts are rendered
using Pango.

Music notation fonts can be described as a set of specific glyphs,
ordered in several families.  The following syntax allows various
LilyPond @code{feta} non-text fonts to be used directly in markup
mode:

@lilypond[quote,verbatim,relative=2]
a1^\markup {
  \vcenter {
    \override #'(font-encoding . fetaBraces)
    \lookup #"brace120"
    \override #'(font-encoding . fetaNumber)
    \column { 1 3 }
    \override #'(font-encoding . fetaDynamic)
    sf
    \override #'(font-encoding . fetaMusic)
    \lookup #"noteheads.s0petrucci"
  }
}
@end lilypond

@noindent
However, all these glyphs except the braces of various sizes contained
in @code{fetaBraces} are available using the simpler syntax described
in @ref{Music notation inside markup}.

When using the glyphs contained in @code{fetaBraces}, the size of the
brace is specified by the numerical part of the glyph name, in
arbitrary units.  Any integer from @code{0} to @code{575} inclusive
may be specified, @code{0} giving the smallest brace.  The optimum
value must be determined by trial and error.  These glyphs are all
left braces; right braces may be obtained by rotation, see
@ref{Rotating objects}.

Three families of text fonts are made available: the @emph{roman}
(serif) font, that defaults to New Century Schoolbook, the @emph{sans}
font and the monospaced @emph{typewriter} font -- these last two
families are determined by the Pango installation.

Each family may include different shapes and series.  The following
example demonstrates the ability to select alternate families, shapes,
series and sizes.  The value supplied to @code{font-size} is the
required change from the default size.

@lilypond[quote,verbatim,relative=2]
\override Score.RehearsalMark #'font-family = #'typewriter
\mark \markup "Ouverture"
\override Voice.TextScript #'font-shape = #'italic
\override Voice.TextScript #'font-series = #'bold
d2.^\markup "Allegro"
\override Voice.TextScript #'font-size = #-3
c4^smaller
@end lilypond

@noindent
A similar syntax may be used in markup mode; however in this case it
is preferable to use the simpler syntax explained in @ref{Selecting
font and font size}:

@lilypond[quote,verbatim]
\markup {
  \column {
    \line {
      \override #'(font-shape . italic)
      \override #'(font-size . 4)
      Idomeneo,
    }
    \line {
      \override #'(font-family . typewriter)
      {
        \override #'(font-series . bold)
        re
        di
      }
      \override #'(font-family . sans)
      Creta
    }
  }
}
@end lilypond

Although it is easy to switch between preconfigured fonts, it is also
possible to use other fonts, as explained in the following sections:
@ref{Single entry fonts} and @ref{Entire document fonts}.

@node Single entry fonts
@unnumberedsubsubsec Single entry fonts

Any font that is installed on the operating system and recognized by
FontConfig may be used in a score, using the following syntax:

@lilypond[quote,verbatim,relative=2]
\override Staff.TimeSignature #'font-name = #"Charter"
\override Staff.TimeSignature #'font-size = #2
\time 3/4

a1_\markup {
  \override #'(font-name . "Vera Bold")
    { Vera Bold }
}

It is possible to change the fonts to be used as the default fonts in
the @emph{roman}, @emph{sans} and @emph{typewriter} font families by
specifying them, in that order, as shown in the example below.  For an
explanation of fonts, see @ref{Fonts explained}.
