@c . {Overview}
LilyPond is linked to GUILE, GNU's Scheme library for extension. The
Scheme library provides the glue that holds together the low-level
-routines and separate modules general, which are C++
+routines and separate modules general, which are C++.
When lilypond is run to typeset sheet music, the following happens:
@itemize @bullet
* Notes::
* Easy Notation note heads ::
* Tie::
+* Tuplets::
* Rests::
* Skip::
* Note mode::
@end lilypond
If you dislike the amount of ties created for a chord, you set
-@code{Thread.sparseTies} to true, resulting in a smaller number of
+@code{Voice.sparseTies} to true, resulting in a smaller number of
ties:
@lilypond[fragment,verbatim,center]

@end lilypond
@lilypond[fragment, singleline]

@end lilypond

At present, the tie is implemented as a separate thing, temporally
located in between the notes. There is also no way to convert
between tied notes, dotted notes and plain notes.

Similarly, the curvature of a slur is adjusted to stay clear of note
heads and stems. When that would increase the curvature too much, the
slur is reverted to its default shape. The threshold for this decision

-@cindex @code{\lyrics}
+To print lyrics in LilyPond, you must first make a music expression from
+the lyric text. When they're in a music expression, that music
+expression can be printed by selecting an appropriate context. We shall
+discuss lyric printing in this order.
-Lyrics mode is introduced by the keyword @code{\lyrics}. This mode has
-rules that make it easy to include punctuation and diacritical marks in
-words: The purpose of Lyrics mode is that you can enter lyrics in @TeX{}
-format or a standard encoding without needing quotes. The precise
-definition of this mode is ludicrous, and this will remain so until the
-authors of LilyPond acquire a deeper understanding of character
-encoding, or someone else steps up to fix this.
-
-A word in Lyrics mode begins with: an alphabetic character, @code{_},
-@code{?}, @code{!}, @code{:}, @code{'}, the control characters @code{^A}
-through @code{^F}, @code{^Q} through @code{^W}, @code{^Y}, @code{^^},
-any 8-bit character with ASCII code over 127, or a two-character
-combination of a backslash followed by one of @code{`}, @code{'},
-@code{"}, or @code{^}.
-
-Subsequent characters of a word can be any character that is not a digit
-and not white space. One important consequence of this is that a word
-can end with `@code{@}}', which may be confusing. However, LilyPond will
-issue a warning. Any @code{_} character which appears in an unquoted
-word is converted to a space. This provides a mechanism for introducing
-spaces into words without using quotes. Quoted words can also be used
-in Lyrics mode to specify words that cannot be written with the above
-rules. Here are some examples. Not all of these words are printable by
-@TeX{}.
-@example
-Ah! % a word
-2B_||_!2B % not a word because it starts with a digit
-``Hello'' % not a word because it starts with `
-_ _ _ _ % 4 words, each one a space

+You can enter lyrics in a special input mode of LilyPond. This mode is

Syllables are entered like notes, with pitches replaced by text. For
-example, @code{Twin-4 kle4 twin-4 kle4} enters four syllables, each
-with quarter note duration. Note that the hyphen has no special
-meaning for lyrics, and does not introduce special symbols. See

+simultaneous music expressions. This means you can enter chords by name,
+and print them as note head, or enter as notes and print as chord names:

+

+attempt to be intelligent, if you enter @code{f bes d}, it does no
+attempt to find out whether it this is an inversion.

This mechanism is fairly crude, since you can only set, but not modify,
the definition of a grob. For this reason, there is a more advanced
mechanism: you can add a property on top of an existing definition, or
remove a property: @code{\override} adds a settings, @code{\revert}
removes that setting.

+@node Font selection
+@subsection Font selection
+
+Most graphics in LilyPond are composed of characters of fonts. You can
+alter the characteristics of the font by setting certain grob
+properties. The mechanism that is used for this resembles LaTeX's New
+Font Selection Scheme. Within this scheme, a font is entirely
+characterized by its font name.
+
+For each grob that uses fonts (in other words, each grob that supports
+@code{font-interface}) a font-name must be selected before it can be
+printed. The font name is selected by looking at a number of grob
+properties:
+
+@table @code
+@item font-family
+ The general class of the typeface. Supported are roman (Computer
+Modern), braces (for piano staff braces), music (the standard music
+font), dynamic (font for dynamic signs) and typewriter
+
+@item font-shape
+ A symbol indicating the shape of the font, a finer gradation than
+ font-family. Choices are italic and upright
+@item font-series
+ Symbol indicating the serie of the font. Series form a finer gradation
+ than font-shape. Choices are medium and bold.
+
+@item font-relative-size
+ A number indicating the size relative the standard size. For example,
+ with 20pt staff height, relative size -1 corresponds to 16pt staff
+ height, and relative size +1 corresponds to 23 pt staff height.
+
+@item font-design-size
+A number indicating the design size of the font.
+
+This is a feature of the Computer Modern Font: each point size has a
+slightly different design. Smaller design sizes are relatively wider,
+which enhances readability. Scalable type faces such TrueType and Adobe
+Type1 usually come as ``one design fits all sizes''.
+
+@item font-name
+ The name of the font, without the design size, eg. @code{cmr},
+@code{cmti}, etc. Setting this overrides font-family, font-shape and
+font-series.
+
+@end table
+
+The font is selected by taking the first font that satisfies all
+qualifiers specified. You can override any of these fields through
+@code{\override} and @code{\revert}. The special value @code{*} matches
+any value for that qualifier.
+
+@example
+ \property Lyrics.LyricText \override #'font-series = #'bold
+ \property Lyrics.LyricText \override #'font-shape = #'*
+@end example
+
+@cindex @code{font-style}
+
+There are also pre-cooked font selection qualifiers. These are selected
+through the grob property @code{font-style}. For example, the style
+@code{finger} selects family @code{number} and relative size @code{-3}.
+Styles available include: volta, finger, tuplet, timesig, mmrest,
+script, large, Large and dynamic.
+
+The style sheets and tables for selecting fonts are located in
+@file{scm/font.scm}. Refer to this file for more information.
+
+@refbugs
+
+Relative size is not linked to any real size. There is no mechanism to
+select magnifications of fonts, meaning that you can not scale fonts
+continuoussly. There is no style sheet provided for other fonts besides
+the @TeX{} family.

@subsubsection Default output
Music in LilyPond is entered as a music expression. Notes, rests, lyric
syllables are music expressions, and you can combine music expressions
to form new ones, for example by enclosing a list of expressions in
-@code{\sequential @{ @}} or @code{< >}. In this example, a compound
-expression is formed out of the quarter note @code{c} and a quarter note
-@code{d}:
+@code{\sequential @{ @}} or @code{< >}. In the following example, a
+compound expression is formed out of the quarter note @code{c} and a
+quarter note @code{d}:
@example
\sequential @{ c4 d4 @}
@code{<} @var{musicexprlist} @code{>}
@end example
for simultaneous music.
-Other compound music expressions include
-@example
- \repeat @var{expr}
- \transpose @var{pitch} @var{expr}
- \apply @var{func} @var{expr}
- \context @var{type} = @var{id} @var{expr}
- \times @var{fraction} @var{expr}
-@end example
-
In principle, the way in which you nest sequential and simultaneous to
produce music is not relevant. In the following example, three chords
are expressed in two different ways:
}
@end lilypond
-However, in some cases, LilyPond will also try to choose contexts, and
-use the structure of the music expression to do so. This can have
-undesired effects: for example, LilyPond will create a separate staff
-for each note if you start a @code{\score} with a chord:
-@lilypond[verbatim,center,singleline]
- \score {
- \notes <c''4 e''>
- }
-@end lilypond
- The solution is to explicitly instantiate the context you desire.
-In this case this is typically a Voice context
-@lilypond[verbatim,center,singleline]
- \score {
- \notes\context Voice <c''4 e''>
- }
-@end lilypond
-If you use @code{\context Staff} you will get separate stems for each
-note head, leading to collisions, so don't use that.
+Other compound music expressions include

+ \repeat @var{expr}
+ \transpose @var{pitch} @var{expr}
