-@node Introduction
-@section Introduction
-
-
-LilyPond prints music from a specification that you, the user, supply.
-You have to give that specification using a @emph{language}. This
-chapter is a gentle introduction to that language.
-
-This tutorial will demonstrate how to use Lilypond by presenting
-examples of input along with resulting output. We will use English
-terms for notation. In case you are not familiar with those, you may
-consult the glossary that is distributed with LilyPond.
+Operating lilypond is done through text files: to print a piece of
+music, you enter the music in a file. When you run lilypond, that
+file is read, and after some computations, the program produces a file
+containing the sheet music that you can print or view.
-@cindex examples, tutorial
+This tutorial starts with a small introduction to the LilyPond music
+language. After this first contact, we will show you how to run
+LilyPond to produce printed output; you should then be able to create
+your first sheets of music. The tutorial continues with more and more
+complex examples.
-The examples discussed are included in the distribution, in the
-subdirectory @file{input/tutorial/}.@footnote{When we refer
-to filenames, they are relative to the top directory of the source
+Some of the examples discussed are included as separate files in the
+distribution, in the subdirectory @file{input/tutorial/} of the source
package.
-@cindex file names
-} We recommend that you experiment with writing Lilypond input yourself,
-to get a feel for how the program behaves.

-@section Running LilyPond
+In this section, we show how to make small, very simple pieces of
+music in LilyPond. If you have not seen LilyPond input files before,
+this section is for you.
+
+You get a simple note by typing its note name, from @code{a} through
+@code{g}. So if you enter
+@quotation
+@example
+c d e f g a b
+@end example
+@end quotation
+then the result looks like this:
+@quotation

+\property Staff.TimeSignature = \turnOff
+\transpose c'' { c d e f g a b }
+@end lilypond
+@end quotation

-Before we dive into describing the input language of LilyPond, we first
-show you through the procedure for getting notes on your screen and out
-of your printer.
+We will continue with this format: first we show a snippet of input,
+then the resulting output.
-The first step is creating an input file. Using your favorite
-text-editor, create @file{test.ly} containing
+The length of a note is specified by adding a number, ``@code{1}'' for a
+whole note, ``@code{2}'' for a half note, and so on:

-@cindex PostScript
-@cindex Printing output
-@cindex GhostScript
-@cindex @code{lpr}
-PostScript is a page description language, similar to PDF. Some printers
-can understand a postscript file directly, but the cheapers need the
-intervention of GhostScript, a PostScript emulator that runs on your
-computer instead of your printer. Most Linux distributions nowadays have
-GhostScript running ``in the background'', so any configured printer
-will act as a PostScript printer. Assuming this, the
-following command will print the file
-@example
- lpr test.ps
-@end example
-If this does not make your printer produce a page of music, then you
-should look into installing and configuring ghostscript. Refer to
-GhostScript's website at @uref{http://www.ghostscript.com}.
-
-There are two different routes: firstly, you can add titling to the
-output. This is done by a separate program called ly2dvi: this program
-first calls LilyPond to process the @file{.ly} file, and then runs
-@TeX{} on it to produce a @file{.dvi} file with proper margin settings
-and titling.

+@end lilypond
+@end quotation
+@separate
+From these commands and notes, a piece of music can be formed. A piece
+of music is made by enclosing it in ``@code{\notes @{ ... @}}''.
+LilyPond then knows that music follows (and not lyrics, for example):
+
+@quotation
@example
- ly2dvi test.ly
+\notes @{
+ \time 3/4
+ \clef bass
+ c2 e4 g2.
+ f4 e d c2.
+@}
@end example
-After some disk-activity, you should end up with a @file{.dvi} file.
-6
-Secondly, you can generate PostScript directly. This is not very useful
-currently, but here goes:
-@cindex PostScript output
+@end quotation
+@separate
+
+At this point, the piece of music is ready to be printed. This is done
+by combining the music with a printing command.
+
+The printing command is the so-called ``@code{\paper}'' block. You
+will see later that the @code{\paper} block is necessary to customize
+printing specifics. The music and the @code{\paper} block are combined by
+enclosing them in ``@code{\score @{ ... @}}''. This is what a full
+LilyPond source file looks like:
+
+@quotation
@example
- lilypond -f ps test.ly
+\score @{
+ \notes @{

+LilyPond is the program that computes the sheet music. All other
+things, such as adding titles, page breaking and other page layout,
+are done by a small wrapper program called
+@code{ly2dvi}. @code{ly2dvi} calls lilypond to render the music, and
+then adds the titling and page layout instructions. To process

-A lilypond file combines music with directions for outputting that
-music. The music is combined with the output directions by putting
-them into a @code{\score} block.
-@example
+The DVI file (@file{test.dvi}) contains the same sheet music in a

-@cindex octaves, choosing
-@cindex pitch
-As we will see, pitches are combinations of octave, note name and
-chromatic alteration. In this scheme, the octave is indicated by
-using raised quotes (@code{'}) and ``lowered'' quotes (commas:
-@code{,}). The central C is denoted by @code{c'}. The C one octave
-higher is @code{c''}. One and two octaves below the central C is
-denoted by @code{c} and @code{c,} respectively.
-
-@cindex relative
-For pitches in a long piece you might have to type many quotes. To
-remedy this, LilyPond has a ``relative'' octave entry mode. In this
-mode, octaves of notes without quotes are chosen such that a note is
-as close as possible (graphically, on the staff) to the the preceding
-note. If you add a high-quote an extra octave is added. The lowered
-quote (a comma) will subtract an extra octave. Because the first note
-has no predecessor, you have to give the (absolute) pitch of the note
-to start with.
-@example
+If you can't get the examples to print, then you should look into
+installing and configuring ghostscript. Refer to GhostScript's website
+at @uref{http://www.ghostscript.com}.
- \sequential @{

-@cindex sequential music

+@cindex GhostScript
+@cindex @code{lpr}
+@cindex Printing output
+@cindex PostScript
- \time 3/4;
-
+@unnumberedsubsec Windows users
+Windows users start the terminal by clicking on the LilyPond or Cygwin
+icon. Notepad is sufficient for editing the LilyPond file. Viewing
+the PS file can be done with:
+@quotation
+@example
+@code{gsview32 test.ps}
@end example
-@cindex time signature, setting
-@cindex @code{\time}
- This command changes the time signature of the current piece: a 3/4
-sign is printed. This command is also used to generate bar lines in
-the right spots.
-@example
-
- \key g \major;
-
+@end quotation
+You can also print from the command line by executing:
+@quotation
+@example
+@code{gsview32 /s test.ps}
@end example
-@cindex key signature, setting
-@cindex @code{\key}
- This command changes the current key signature to G-major. Although this
-command comes after the @code{\time} command, in the output, the key
-signature comes before the time signature: LilyPond knows about music
-typesetting conventions.
-@example
+@end quotation
- \repeat "volta" 2
-
-@end example
- This command tells LilyPond that the following piece of music must be
-played twice. The first argument indicates the type of repeat. In this
-case, @code{"volta"} means that volta brackets are be used for
-alternatives---if there were any.
-@example
- @{
-
-@end example
-The subject of the repeat is again sequential music. Since
-@code{\sequential} is such a common construct, a shorthand is provided:
-just leave off @code{\sequential}, and the result is the same.
-@example
+@strong{SUMMARY}
- d4
-
-@end example
- This is a note with pitch @code{d} (determined up to octaves). The
-relative music was started with a @code{c''}, so the real pitch of this
-note is @code{d''}. The @code{4} designates the duration of the note
-(it is a quarter note).
-@example
+To run LilyPond, enter a file, and run the command @code{ly2dvi} on
+that file. The resulting files are either DVI or PostScript, and can
+be viewed with @code{xdvi} (unix) and ghostview (unix and windows)
+respectively. The following table summarizes the constructs that were
+discussed in the previous two sections.
- a b
-
-@end example
-These are notes with pitch @code{a} and @code{b}. Because their
-duration is the same as the @code{g}, there is no need to enter the
-duration (You may enter it anyway, e.g. @code{a4 b4})
-@example
+@multitable @columnfractions .3 .3 .4
- d4 g, g |
-
-@end example
-@cindex bar check
-@cindex @code{|}
-@cindex errors, finding
- Three more notes. The @code{|} character is a `bar check'. When
-processing the music, LilyPond will verify that bar checks are found at
-the start of a measure. This can help you track down errors.
-
-@cindex alteration, chromatic
-@cindex chromatic alteration
-So far, no notes were chromatically altered. Here is the first one
-that is: @code{fis}. Lilypond by default uses Dutch note names, and
-``Fis'' is the Dutch note name for ``F sharp''. However, there is no
-sharp sign in the output. The program keeps track of key signatures,
-and will only print accidentals if they are needed.
-@example
+@item @b{Syntax}
+@tab @b{Description}
+@tab @b{Example}
- c8 d e fis
-
-@end example
-LilyPond guesses were beams can be added to eighth and shorter notes.
-In this case, a beam over 4 eighths is added.

+\property Staff.Clef = \turnOff
+c1 c2 c8 c16
+@end lilypond
- c4 d8( )c b a( )b4 c8 b a g |
-
-@end example
- The next line shows how to make a slur: the beginning and ending note
-of the slur is marked with an opening and closing parenthesis
-respectively. In the line shown above, this is done for two slurs.
-Slur markers (parentheses) are put between the slurred notes.
-@example
+@item @code{. ..}

+
+@c accidentals...
+There are some interesting points to note in this example.
+Accidentals (sharps and flats) don't have to be marked explicitly: you
+just enter the note name, and LilyPond determines whether or not to
+print an accidental. Bar lines and beams are drawn automatically.
+LilyPond calculates line breaks for you; it doesn't matter where you
+make new lines in the source file. Finally, the order of time, key and
+clef changes is not relevant: lilypond will use standard notation
+conventions for ordering these items.
+
+The example also indicates that a piece of music written in a high
+register needs lots of quotes. This makes the input less readable,
+and is therefore also a potential source of errors.
+
+The solution is to use ``relative octave'' mode. In practice, this is
+the most convenient way to copy existing music. To use relative mode,
+add @code{\relative} before the piece of music. You must also give a
+note from which relative starts, in this case @code{c''}. If you type
+no octavation quotes, relative mode chooses the note that is closest
+to the previous one, which is often just the one you need.
+@c don't use commas or quotes in this sentence
+For example: @code{c f} goes up; @code{c g} goes down:
+
+@quotation
+@example
+\relative c'' @{
+ c f c g c
@}
+@end example
-text = \lyrics @{

+@c needed better, maybe even redundant explanation
+@c grappig: Pa vond het heel logies, en slim toen-i eenmaal begreep.
+@c in eerste instantie drong het `relative' niet door zonder extra uitleg.
+You can make a large interval by adding octavation quotes. Note that
+quotes or commas do not determine the absolute height of a note;
+the height of a note is relative to the previous one.
+@c don't use commas or quotes in this sentence
+For example: @code{c f,} goes down; @code{f, f} are both the same;
+@code{c c'} are the same; and @code{c g'} goes up:

+
+To print more than one staff, each piece of music that makes up a staff
+is marked by adding @code{\context Staff} before it. These

+demonstrated here:
+
+@quotation
+@lilypond[fragment,verbatim]
+<
+ \context Staff = staffA { \clef violin c'' }
+ \context Staff = staffB { \clef bass c }
+>
+@end lilypond
+@end quotation
+
+In this example, @code{staffA} and @code{staffB} are names that are
+given to the staves. It doesn't matter what names you give, as long
+as each staff has a unique name.
+
+@separate
+
+We can typeset a melody with two staves now:
+
+@quotation
+@lilypond[verbatim,singleline]

+ \clef bass
+ c2 e4 g2.
+ f4 e d c2.
+ }
+ >
+ \paper {}
+}
+@end lilypond
+@end quotation
+
+Notice that the time signature is specified in one melody staff only
+(the top staff), but is printed on both. LilyPond knows that the time
+signature should be the same for all staves.
+
+@separate
+
+Common accents can be added to a note using @code{-.}, @code{--}, @code{->}:
+@quotation
+@lilypond[verbatim,relative 1]
+c-. c-- c->
+@end lilypond
+@end quotation
+@separate
+
+Dynamic signs are made by adding the markings to the note:
+@quotation
+@lilypond[verbatim,relative 1]
+c-\ff c-\mf
+@end lilypond
+@end quotation
+@separate
+
+Crescendi are started with the commands @code{\<} and @code{\>}. The
+command @code{\!} finishes a crescendo on the following note.
+@quotation
+@lilypond[verbatim,relative 1]
+c2\< \!c2-\ff \>c2 \!c2
+@end lilypond
+@end quotation
+@separate
+
+Chords can be made by surrounding notes with @code{<} and @code{>}:
+@quotation
+@lilypond[relative 0, fragment,verbatim]
+r4 <c e g> <c f a>
+@end lilypond
+@end quotation
+@separate
+
+@ignore
+@c te diepzinnig?
+@c hmm, te losjes, iig
+In general, @code{ < @var{stuff} > } is used when @var{stuff} all
+happens at the same time, like in chords, or (like in the two-staff
+example above) in a bunch of stacked staves.
+@end ignore
+
+Of course, you can combine beams and ties with chords. Notice that
+beam and tie markings must be placed outside the chord markers:
+@quotation
+@lilypond[relative 0, fragment,verbatim]
+r4 [<c8 e g> <c8 f a>] ~ <c8 f a>
+@end lilypond
+@end quotation
+
+When you want to combine chords with slurs and dynamics, technical
+detail crops up: you have type these commands next to the notes, which
+means that they have to be inside the @code{< >}:
+
+
+@quotation
+@example
+r4 <c8 e g \> ( > <c e g> <c e g> < ) \! c8 f a>
+@end example
+@lilypond[relative 0, fragment]
+\slurUp
+r4 <c8 e g \> ( > <c e g> <c e g> < ) \! c8 f a>
+@end lilypond
+@end quotation
+@separate
+
+There is one golden rule that you should keep in mind when writing
+LilyPond input:
+@quotation
+@strong{DO NOT START A PIECE WITH A CHORD}
+@end quotation
+Of course, it is a allowed, but the result might not be what you expect:
+@quotation
+@lilypond[verbatim,singleline]
+\score { \notes <c'2 e'2> }
+@end lilypond
+@end quotation
+@separate
+
+If you have a piece that starts with a chord, then you must explicitly
+state that the notes of the chord are to be put on the same staff, in
+the same voice. This is done by specifying @code{\context Staff} for
+the notes:
+

+}
+\paper { linewidth = -1. }
+}
+@end lilypond
+
+
+@cindex lyric mode
+@cindex @code{\lyrics}
+
+
+To print lyrics, you must enter them, and then instruct lilypond to
+handle the lyrics by printing them.
+You can enter lyrics in a special input mode of LilyPond. This mode is
+called Lyrics mode, and it is introduced by the keyword @code{\lyrics}.
+The purpose of this mode is that you can enter lyrics as plain text,
+punctuation and accents without any hassle.
+
+Syllables are entered like notes, with pitches replaced by text. For
+example, @code{Twin- kle twin- kle} enters four syllables. Note that
+the hyphen has no special meaning for lyrics, and does not introduce
+special symbols.
+
+Spaces can be introduced into a lyric either by using quotes:
+@code{"He could"4 not4} or by using an underscore without quotes:
+@code{He_could4 not4}. All unquoted underscores are converted to
+spaces.
+
+These are the lyrics for the free software song:
+
+@example
+ \lyrics @{
+ Join us now __ and
+ share the soft -- ware; @}
+@end example
+
+As you can see, extender lines are entered as @code{__}. This will
+create an extender, a line that extends over the entire duration of
+the lyric. This line will run all the way to the start of the next
+lyric, so you may want to shorten it by using a blank lyric (using
+@code{_}).
+
+
+If you can use have hyphens at the end of a syllable, i.e.
+@example
+ soft- ware
+@end example
+but then the hyphen will be attached to the to the end of the first
+syllable.
+
+If you want them centered between syllables you can use the special
+`@code{-}@code{-}' lyric as a separate word between syllables. The
+hyphen will have variable length depending on the space between
+syllables. It will be centered between the syllables.
+
+Normally, the notes that you enter are transformed into note heads.
+Note heads alone make no sense, they need surrounding information: a key
+signature, a clef, staff lines, etc. They need @emph{context}. In
+LilyPond, these symbols are created by objects called `interpretation
+contexts'. Interpretation contexts exist for generating notation
+(`notation context') and for generating sound (`performance
+context'). These objects only exist during a run of LilyPond.
+
+When LilyPond interprets music, it will create a Staff context.
+We don't want that default here, because we want lyric. The
+command
+@example
+ \context Lyrics
+@end example
+explicitly creates an interpretation context of
+@code{Lyrics} type to interpret the song text that we entered.
+
+The melody of the song doesn't offer anything new:
+@example
+ \notes \relative c' @{
+ \time 7/4
+ d'2 c4 b16 ( a g a b a b ) c a2
+ b2 c4 b8 ( a16 g ) a4 g2 @}
+@end example
+
+Both can be combined with the @code{\addlyrics}:
+@example
+\addlyrics
+ \notes \relative c' @dots{}
+ \context Lyrics \lyrics @dots{}
+@end example
+
+The lyrics are also music expressions, similar to notes. What happens
+here, is that each syllable of the lyrics is put under the a note of
+the melody.

+@node Fine tuning a piece
+@section Fine tuning a piece
+
+In this section, we show some ways to fine tune the final output of a
+piece. We do so using a single measure of a moderately complex piano
+piece: a Brahms intermezzo (opus 119, no. 1).
+@cindex Brahms, Johannes
+
+The code for the untuned example shows us some new things.
+
+@lilypondfile[verbatim]{brahms-original.ly}
+
+
+@cindex dynamics
+@cindex loudness
+@cindex forte
+@cindex crescendo
+@cindex @code{\<}
+@cindex @code{\!}
+
+The crescendo is ended at the half note by the escaped exclamation
+mark @code{\!}.
+
+Hairpin dynamics can be indicated using @code{\>} to start a
+decrescendo, and @code{\!} to end one. The crescendo is started using
+@code{\<} and also ended using @code{\!}. Absolute dynamics can be
+entered using @code{\p}, @code{\mf}, etc. All these commands apply to
+the complete chord where they are entered, but for syntactical
+reasons, they must be attached to one of the notes of the chord.
+
+@cindex fingering instructions
+
+Fingering indications are entered simply using @code{-@var{N}}, where
+@var{N} is a digit.
+
+Now that we have the basic piece of music entered, we want to fine
+tune it, so we get something that resembles the original printed
+edition by Schott/Universal Edition:
+
+@lilypondfile{brahms-tweaked.ly}
+
+@cindex tuning grob behavior
+
+The basic process that we follow is that we override defaults in the
+printing system. We do this by setting variables in so-called grobs.
+Printed symbols are internally represented by Graphical Objects
+(Grobs). Each grob is described by a bunch of settings. Every
+setting is a variable: it has a name, and you can assign a value to
+the variable. These setting determine the fonts, offsets, sub-routines
+to be called on the grob, etc. The initial values of these settings
+are set in the Scheme file @file{scm/grob-description.scm}.
+
+@cindex slur attachments
+
+We start with the slur: the slur in the upper part, running from the F
+sharp to the A, runs from stem to stem in the printed edition, while
+ours starts from the note head at the left. The following property
+setting forces all slurs to run from stem to stem (and not from or to
+note head)
+
+@example
+ \property Voice.Slur \set #'attachment = #'(stem . stem)
+@end example
+
+More precisely, this command extends the definition of the @code{Slur}
+object in the current @code{Voice}. The variable @code{attachment} is
+set to the pair of symbols @code{'(stem . stem)}.
+
+Although this is useful information, it is not very helpful: the
+lilypond backend supports approximately 240 variables like
+@code{attachment}, each with their own meaning and own type
+(eg. number, symbol, list, etc). Besides slur, LilyPond has 80
+different types of Grobs, that may be created in 14 different context
+types besides Voice.
+
+@cindex internal documentation
+@cindex finding grobs
+@cindex grob descriptiosn
+
+The interesting information is how you can figure out which properties
+to tune for your own scores. To discover this, you must have a copy of
+the internals document. This is a set of HTML pages, which should be
+included if you run a binary distribution@footnote{You can also
+compile them by executing @code{make -C Documentation/user/
+out/lilypond-internals.html} in the source package.}. This document is
+also available on the web: go to the lilypond website, click
+``Documentation: other'' on the side bar, click
+``lilypond-internals'', under information for users.
+
+You might want to bookmark either the HTML files on disk, or the one
+on the web. One word of caution is in place here: the internals
+documentation is generated from the definitions that lily uses. For
+that reason, it is strongly tied to the version of LilyPond that you
+use. Before you proceed, please make sure that you are using the
+documentation that corresponds to the LilyPond version that you use.
+
+Suppose that you wanted to tune the behavior of the slur. The first
+step is to get some general information on slurs in lilypond. Turn to
+the index, and look up ``slur''. The section on slurs says
+@quotation
+The grob for this object is @internalsref{Slur}, generally in
+@internalsref{Voice} context.
+@end quotation
+
+So the grob for this object is called @code{Slur}, and slurs are
+created in the @code{Voice} context. If you are reading this tutorial
+in the HTML version, then you can simply click Slur, otherwise, you
+must look it up the internal documentation: click ``grob overview'' ,
+and select ``slur'' (the list is alphabetical.)
+
+Now you get a list of all the properties that the slur object
+supports, along with their default values. Among the properties we
+find the @code{attachment} property with its default setting.
+The property documentation explains that the following setting will
+produce the desired effect:
+@example
+ \property Voice.Slur \set #'attachment = #'(stem . stem)
+@end example
+
+If you ran the previous example, you have unknowingly already used
+this kind of command. The @file{ly/property-init.ly} contains the
+definition of @code{\stemUp}
+@example
+ stemUp = \property Voice.Stem \set #'direction = #1
+@end example
+
+
+We also want to move around the fingering `3'. In the printed edition
+it is not above the stem, but a little lower, slightly left of the
+stem. From the user manual, we find that the associated grob is called
+@code{Fingering}, but how do we know if we should use @code{Voice} or
+@code{Staff}. In many cases, @code{Voice} is a safe bet, but you can
+also deduce this information from the internals documentation: if you
+visit the documentation of @code{Fingering}, you will notice
+@example
+Fingering grobs are created by: Fingering_engraver
+@end example
+
+
+
+Clicking @code{Fingering_engraver} will show you the documentation of
+the module responsible for interpreting the fingering instructions and
+translating them to a @code{Fingering} grob. Such a module is called
+an @emph{engraver}. The documentation of the @code{Fingering_engraver}
+says,
+@example
+Fingering_engraver is part of contexts: Voice and TabVoice
+@end example
+so tuning the settings for Fingering should be done using either
+@example
+ \property Voice.Fingering \set @dots{}
+@end example
+or
+@example
+ \property TabVoice.Fingering \set @dots{}
+@end example
+
+Since the @code{TabVoice} is only used for tab notation, we see that
+the first guess @code{Voice} was indeed correct.
+
+@cindex setting grob properties
+@cindex @code{extra-offset}
+
+For shifting the fingering, we use the grob property
+@code{extra-offset}. The following command manually adds an offset to
+the object. We move it a little to the left, and 1.8 staff space
+downwards.
+@example
+ \property Voice.Fingering \set #'extra-offset = #'(-0.3 . -1.8)
+@end example
+The @code{extra-offset} is a low-level feature: it moves around
+objects in the printout; the formatting engine is completely oblivious
+to these offsets. The unit of these offsets are staff-spaces.
+
+@cindex reverting grob properties
+@cindex undoing grob properties
+
+We only want to offset a single grob, so after the F-sharp, we must
+undo the setting. The technical term is to revert the grob property.
+@example
+ \property Voice.Fingering \revert #'extra-offset
+@end example
+
+@cindex property types
+@cindex translator properties
+@cindex grob properties
+@cindex music properties
+
+
+There is three different types of variables in LilyPond, something
+which is confusing at first (and for some, it stays like that).
+Variables such as @code{extra-offset} and @code{attachment} are called
+grob properties. They are something different from the translator
+properties, like @code{autoBeaming}. Finally, music expressions are
+internally also stored using properties, so-called music
+properties. You will encounter the latter type if you run Scheme
+functions on music using @code{\apply}.
+
+The second fingering instruction should be moved up a little, to avoid
+a collision with the slur. This could be achieved with
+@code{extra-offset}, but in this case, a simpler mechanism also
+works. We insert an empty text between the 5 and the note. The empty
+text pushes the fingering instruction away:
+@example
+ a^" "^#'(finger "5")
+@end example
+
+Lilypond tries to put fingering instructions closer to the notes as
+text instructions. To insert an empty text (@code{^" "}) between the
+finger and the note, we have disguised the fingering instruction as a
+text: @code{(finger "5")}.
+
+Normally, one would specify dynamics in a single voice, and start and
+end dynamics (such as @b{f} and @b{p}) will be aligned with
+hairpins. In this case, we want the decrescendo to be in a different
+place from the piano sign. We achieve this by putting the dynamic
+markings in different voices. The crescendo should be above the upper
+staff. This can be forced by the precooked command
+@example
+ \dynamicsUp
+@end example
+
+However, if you do that, the decrescendo will be too close to the
+upper voice, and collide with the stems. Looking at the manual for
+dynamics, we notice that ``Vertical positioning of these symbols is
+handled by the @internalsref{DynamicLineSpanner} grob.''. If we turn
+to the documentation of @code{DynamicLineSpanner}, we find that the
+@code{DynamicLineSpanner} supports several so-called
+`interfaces'. This grob not only puts dynamic objects next to the
+staff (@code{side-position-interface}), but it also groups dynamic
+objects (@code{axis-group-interface}), is considered a dynamic sign
+itself (@code{dynamic-interface}) and is a grob: it has the
+@code{grob-interface}, with all the variables that come with it.
+
+For the moment, we are interested in the side positioning:
+@quotation
+ side-position-interface
+
+ Position a victim object (this one) next to other objects (the
+ support). In this case, the direction signifies where to put the
+ victim object relative to the support (left or right, up or down?)
+@end quotation
+Between the grob and its support (in this case: the notes in the voice
+going down), there should be more space. This space is controlled by
+@code{padding}, so we increase it.
+@example
+ \property Voice.DynamicLineSpanner \override #'padding = #5.0
+@end example
+
+This command is almost like the command for setting slur attachments,
+but subtly different in its details. Grob properties can be
+manipulated with two commands: @code{\override} extends the grob
+variables with a setting, and @code{\revert} releases this
+setting. This has a certain theoretical appeal: the operations are
+simple and symmetric. For practical use, it can be cumbersome. Both
+commands act like parentheses: you should carefully balance the use of
+@code{\override} and @code{\revert}. The @code{\set} command is more
+friendly: it first does a @code{\revert} followed by @code{\override}.
+
+Finally, Brahms uses music notation is a slightly unorthodox way. Ties
+usually happen only within one voice. In this piece, the composer
+gladly produces ties that jump voices. We deal with this by faking
+these ties: whenever we need such a tie, we insert a notehead in a
+different voice, and blank the stem. This is done in the following
+snippet of code.
+
+@example
+ \property Voice.Stem \set #'transparent = ##t
+ d'
+ \property Voice.Stem \revert #'transparent
+@end example
+
+Finally, the last tie is forced up using @code{\tieUp}.
+
+
+@node An orchestral score
+@section An orchestral score
+
+@menu
+* The full score::
+* Extracting an individual part::
+@end menu
+
+
+Our last two examples show a way to setup the music for an orchestral
+score. When typesetting a piece for several instruments, you'll want to
+create a conductor's full score, alongside several individual parts.
+
+LilyPond is well suited for this task. We will declare the music for
+each instrument individually, giving the music of each instrument its
+own name. These pieces of music are then combined in different
+@code{\score} blocks to produce different combinations of the score.
+
+This orchestral score example consists of three input files. In the
+first file, @file{os-music.ly}, we define the music for all
+instruments. This file will be used both for producing the score and
+the separate parts. Other files reference this file by doing
+@code{\include "os-music.ly"}.
+
+If you were to run LilyPond on this file, no printable output would be
+produced.
+
+@example
+% os-music.ly
+\header @{
+ title = "Zo, goed lieverd?"
+ subtitle = "How's, this babe?"
+ composer = "JCN"
+ opus = "1"
+ piece = "Laid back"
+@}

+ \times 4/5 @{ as8 as as as as @}
+ R1
+@}
+corno = \notes\relative c' @{
+ bes4 d f, bes d f, bes d
+@}
+@end example
+
+We will not go through the input line by line, but only indicate and
+explain the new elements.
+
+
+@separate
+@example
+global = @{
+ \time 2/4
+ \skip 2*4 \bar "|.";
+@}
+@end example
+
+Declare setting to be used globally. The @code{\skip} command produces
+no output, but moves forward in time: in this case, the duration of a
+half note (@code{2}), and that four times (@code{*4}). This brings us
+to the end of the piece, and we can set the end bar.
+
+@separate
+@example
+Key = \notes \key as \major

+Declare the key signature of the piece and assign it to the identifier

@end example
-@file{ly2dvi} runs it through LaTeX. LaTeX is a text-formatting system
-built on top of @TeX{}. It's very popular in the academic world. If LaTeX
-is successful, this will produce a @file{.dvi} file, containing both the
-titling and notes. @code{ly2dvi} completes its task by deleting the two
-temporary files, leaving only @file{layout.dvi}.
-
-Next, now we'll look at the examples line by line to explain new things.
+This piece of Scheme code sets the Scheme variable
+@code{point-and-click} to the value @var{line-column-location} (which
+itself is a Scheme procedure).
-@example
-\version "1.3.124";
-@end example
-Lilypond and its language are still under development, and occasionally,
-details of the syntax are changed. This fragment indicates for which
-version the input file was written. When you compile this file, the
-version number will be checked, and you will get a warning when the file
-is too old.
+Editing input files can be complicated if you're working with large
+files: if you're digitizing existing music, you have to synchronize
+the .ly file, the sheet music on your lap and the sheet music on the
+screen. The point-and-click mechanism makes it easy to find the
+origin of an error in the LY file: when you view the file with Xdvi
+and click on a note, your editor will jump to the spot where that note
+was entered. For more information, see @ref{Point and click}.
-This version number is also used by the @code{convert-ly} program (See
-@ref{convert-ly}), which uses it update the file to the latest lily
-version.
+@separate
@example
- \header @{ title = "Two miniatures"; @}
+#(define text-flat '((font-relative-size . -2)
+ (music "accidentals--1")))
@end example
-This sets the titling information for the entire file.
+When naming the tuning of the french horn, we'll need a piece of text
+with a flat sign. LilyPond has a mechanism for font selection and
+kerning called Scheme markup text (See @ref{Text markup}). The flat
+sign is taken from the music font, and its name is @code{accidentals--1}
+(The natural sign is called @code{accidentals-0}). The default font is
+too big for text, so we select a relative size of @code{-2}.
+
+@separate
@example
- #(set! point-and-click #t)
+ <
+ \global
@end example
+Of course, all staves are simultaneous and use the same global settings.
-This is Scheme code. It sets the variable @code{point-and-click} to the
-value @var{true}.

-Editing input files can be quite complicated if you're working with
-large files: if you're digitizing existing music, you have to
-synchronize the .ly file, the sheet music on your lap and the sheet

-presently only available on X-windows using patched versions of Xdvi and
-emacs} when you view the file with Xdvi and click on a note using
-control-mousebutton 1@footnote{If you're using a patched xdvik, the
-command is control-mousebutton-2}, your editor will jump to the spot
-where that note was entered.
-
-More information is in in @ref{Point and click}
-
+@separate
@example
- \paper @{
+ \property Score.BarNumber \override #'padding = #3
@end example
-
-The @code{\score} blocks that follow in the file don't have
-@code{\paper} sections, so the settings of this block are substituted: A
-paper block, at top-level, i.e. not in a @code{\score} block sets the
-default page layout.
-
+LilyPond prints bar numbers at the start of each line, but
+unfortunately, they end up a bit too close to the staff in this
+example. A bar number internally is a Grob called @var{BarNumber}.
+BarNumber Grobs can be manipulated through their
+@var{side-position-interface}. One of the properties of a
+@var{side-position-interface} that can be tweaked is the
+@var{padding}: the amount of extra space that is put between this Grob
+and other Grobs. We set the padding to three staff spaces.

+simultaneous mode. We name both voices differently, so that LilyPond
+will actually create two Voice contexts. The flute parts are simple, so
+we specify manually which voice is which: @code{\voiceOne} forces the
+direction of stems, beams, slurs and ties up, @code{\voiceTwo} sets
+directions down.
+

@end example
+Close the flutes staff and woodwind staff group.
-In previous examples, notes were specified in relative octaves,
-i.e. each note was put in the octave that would put it closest to its
-predecessor. Besides relative, there is also absolute octave
-specification, and it is turned on by default. In this input mode, the
-central C is denoted by @code{c'}. Going down, you get @code{c}
-@code{c,} @code{c,,} etc. Going up, you get @code{c''} @code{c'''} etc.
+@separate
+@example
+ \property Staff.instrument = #'(lines "Timpani" "(C-G)")
+@end example
+The timpani staff only shows a new piece of scheme markup, it sets two
+lines of text.
-When you're copying music from existing sheet music, relative octaves
-are probably the easiest to use: it's less typing work and errors are
-easily spotted. However, if you write LilyPond input, either by hand
-(ie. composing) or by computer, absolute octaves are probably less work.
+@separate
+@example
+ \context Voice=one \partcombine Voice
+ \context Thread=one \tromboI
+ \context Thread=two \tromboII
+@end example
+You have seen the notation contexts Staff and Voice, but here's a new
+one: Thread. One or more Threads can be part of a Voice. The Thread
+takes care of note heads and rests, the Voice combine note heads onto a
+stem.
+
+For the trumpets we use the automatic part combiner (see @ref{Automatic
+part combining}) to combine the two simultaneous trumpet parts onto the
+trumpet staff. Each trumpet gets its own Thread context, which must be
+named @code{one} and @code{two}). The part combiner makes these two
+threads share a Voice when they're similar, and splits the threads up
+when they're different.
+
+@separate
+@example
+ \property Staff.instrument = #`(lines "Corno"
+ (columns "(E" ,text-flat ")"))
+@end example
+The french horn has the most complex scheme markup name, made up of two
+lines of text. The second line has three elements (columns), the @code{(E},
+the flat sign @code{text-flat} that we defined before and a final @code{")"}.
+Note that we use a backquote instead of an ordinary quote at the
+beginning of the Scheme expression to be able to access the
+@code{text-flat} identifier, `unquoting' it with a @code{,}.
+
+@separate
+@example
+ \property Staff.transposing = #3
+@end example
+The french horn is to be tuned in E-flat, so we tell the MIDI backend to
+transpose this staff by three steps.
+Note how we can choose different tuning for entering, printing and
+playing, using @code{\transpose} and the MIDI Staff property
+@var{transposing}.
+@separate
@example
- \header @{
+ \notes \key bes \major
@end example
+Therefore, it has a different key.
-The @code{\header} is normally at the top of the file, where it sets
-values for the rest of the file. If you want to typeset different pieces
-from one file (for example, if there are multiple movements, or if
-you're making a etude-book), you can put different @code{\score} blocks
-into the input file. ly2dvi will assemble all LilyPond output files into
-a big document. The contents of \header blocks specified within each
-score, are used for the titling of each movement.
+@separate
@example
- opus = "Opus 1.";
- piece = "Up"; @}
+ indent = 15 * \staffspace
+ linewidth = 60 * \staffspace
@end example
-For example, the Opus number is put at the right, and the piece string
-will be at the left.
+We specify a big indent for the first line and a small linewidth for this
+tutorial.
+@separate
+Usually, LilyPond's predefined setup of notation contexts (Thread,
+Voice, Staff, Staffgroup, Score) is just fine. But in this case, we
+want a different type of Staff context.

-If it looks like incomprehensible gibberish to you, then you are right.
-This example has been doctored to have as many quirks as possible.
+Because we separated the music definitions from the @code{\score}
+instantiations, we can easily define a second score with the music of
+the second flute. This then is the part for the second flute player.
+Of course, we make separate parts for all individual instruments.
+@separate
@example
- stemdown = \property Voice.Stem \override #'direction = #-1
+ \flautoII
@end example
+In this individual part the second flute has a whole staff for itself,
+so we don't want to force stem or tie directions.
-As you can see, this example features more voices on one staff. To make
-room for those voices, their notes have to be stemmed in opposite
-directions. These are the commands to make that happen.
-
-The symbols that are printed, are internally represented by so-called
-Graphical Objects (or more colloquially: Grobs). These statements
-concern the grob called `Stem'. Each grob is described by a bunch of
-settings. These setting determine the fonts, offsets, sub-routines to be
-called on the grob, etc. The initial values of these settings are set
-in the Scheme file @file{scm/grob-description.scm}.
-
-This statement adds a the setting for all Stem grobs in the current
-Voice: @code{direction} is set to @code{-1}, which encodes down. The
-setting remains in effect until it is reverted.
+@separate
+@example
+ \header @{
+ instrument = "Flauto II"
+ @}
+@end example
+The @code{\header} definitions were also read from @file{os-music.ly},
+but we need to set the instrument for this particular score.
+@separate
@example
- \property Voice.Stem \revert #'direction
+ \property Score.skipBars = ##t
@end example
+In the conductor's full score, all bars with rests are printed, but for
+the individual parts, we want to contract pieces of consecutive empty
+bars. LilyPond will do this if Score's @var{skipBars} property to
+true.
-This statement reverts the old setting. If you do this, the effect of a
-@code{\stemdown} or @code{\stemup} is neutralised.
-@code{\override} and @code{\revert} function like a stack: you can push
-values onto the grob-setting-stack with @code{\override} and you pop
-them with @code{\revert}.
+@node Integrating text and music
+@section Integrating text and music
-LilyPond includes the identifiers @code{\stemUp}, @code{\stemDown} along
-with some more often used formatting instructions, but to explain how it
-works, we wrote our own here. Of course, you should use predefined
-identifiers like these if possible: then you will be affected less by
-the implementation changes we occasionally make.
+Sometimes, you might want to use music examples in a text that you are
+writing. For example, if you are writing a musicological treatise, a
+songbook, or (like us) the LilyPond manual. You can make such texts by
+hand, simply by importing a PostScript figure into your wordprocessor.
+However, there is a also an automated procedure:
-@example
-viola = \notes \relative c' \context Voice = viola @{
-@end example
-In this example, you can see multiple parts on a staff. Each part is
-associated with one notation context. This notation context handles
-stems and dynamics (among others). The name of this context is
-@code{Voice}. For each part we have to make sure that there is
-precisely one @code{Voice} context, so we give it an unique name
-(`@code{viola}').
+If you use HTML, La@TeX{} or texinfo, you can mix text and LilyPond
+code. A script called @code{lilypond-book} will extract the music
+fragments, run LilyPond on them, and put back the resulting notation.
+This utility program is described fully in the chapter @ref{Merging text
+and music with lilypond-book}. Here we show a small example. Since the
+example also contains explanatory text, we won't comment on the
+contents.
-@example
-<c4-\f-\arpeggio g' c>
-@end example
-The delimiters @code{<} and @code{>} are shorthands for
-@code{\simultaneous @{} and @code{@}}. The expression enclosed in
-@code{<} and @code{>} is a chord.
+@example
+\documentclass[a4paper]@{article@}
+\begin@{document@}
+
+In a lilypond-book document, you can freely mix music and text. For
+example:
+\begin@{lilypond@}
+ \score @{ \notes \relative c' @{
+ c2 g'2 \times 2/3 @{ f8 e d @} c'2 g4
+ @} @}
+\end@{lilypond@}
+Notice that the music line length matches the margin settings of the
+document.
+
+If you have no \verb+\score+ block in the fragment,
+\texttt@{lilypond-book@} will supply one:
+
+\begin@{lilypond@}
+ c'4
+\end@{lilypond@}
+
+In the example you see here, a number of things happened: a
+\verb+\score+ block was added, and the line width was set to natural
+length. You can specify many more options using \LaTeX style options
+in brackets:
+
+\begin[verbatim,11pt,singleline,
+ fragment,relative,intertext="hi there!"]@{lilypond@}
+ c'4 f bes es
+\end@{lilypond@}
+
+\texttt@{verbatim@} also shows the LilyPond code, \texttt@{11pt@} selects
+the default music size, \texttt@{fragment@} adds a score block,
+\texttt@{relative@} uses relative mode for the fragment, and
+\texttt@{intertext@} specifies what to print between the
+\texttt@{verbatim@} code and the music.
+
+If you include large examples into the text, it may be more convenient
+to put the example in a separate file:
+
+\lilypondfile[printfilename]@{sammartini.ly@}
+
+The \texttt@{printfilename@} option adds the file name to the output.
+
+\end@{document@}
+@end example
-@cindex dynamics
-@cindex loudness
-@cindex forte
-@cindex arpeggio
+Under Unix, you can view the results as follows.

+$ cd input/tutorial
+$ lilypond-book --outdir=out/ lilbook.tex
+lilypond-book (GNU LilyPond) 1.3.146
+Reading `input/tutorial/lilbook.tex'
+Reading `input/tutorial/sammartini.ly'
+@var{lots of stuff deleted}
+Writing `out/lilbook.latex'
+$ cd out
+$ latex lilbook.latex
+@var{lots of stuff deleted}
+$ xdvi lilbook
+@end example
-@code{\f} places a forte symbol under the chord. The forte applies to
-the whole chord, but the syntax requires that commands like forte and
-arpeggio are attached to a note, so here we attach them to the first
-note.
+Notice the @code{outdir} option to lilypond-book. Running lilypond-book
+and running latex creates a lot of temporary files, and you wouldn't want
+those to clutter up your working directory. Hence, we have them created
+in a separate subdirectory.
-@code{\arpeggio} draws an vertical wavy line before the chord,
-signifying an arpeggio.
+The result more or less looks like this:
-@example
- \stemdown
-@end example
+@separate
+In a lilypond-book document, you can freely mix music and text. For
+example:
+@lilypond
+ \score { \notes \relative c' {
+ c2 g'2 \times 2/3 { f8 e d } c'2 g4
+ } }
+@end lilypond
+Notice that the music line length matches the margin settings of the
+document.
-@example
- g'8. b,16
-@end example
-Relative octaves work a little differently with chords. The starting
-point for the note following a chord is the first note of the chord. So
-the @code{g} gets an octave up quote: it is a fifth above the starting
-note of the previous chord (the central C).
+If you have no @code{\score} block in the fragment,
+@code{lilypond-book} will supply one:
-@example
-s1 s2. r4
-@end example
-@code{s} is a spacer rest. It does not print anything, but it does have
-the duration of a rest. It is useful for filling up voices that
-temporarily don't play. In this case, the viola doesn't come until one
-and a half measure later.
+@lilypond
+ c'4
+@end lilypond
-@example
-oboes = \notes \relative c'' \context Voice = oboe @{
-@end example
-Now comes a part for two oboes. They play homophonically, so we
-print the notes as one voice that makes chords. Again, we insure that
-these notes are indeed processed by precisely one context with
-@code{\context}.
-@example

-@end ignore
-@example
-\times 2/3
-@end example
-@cindex tuplet
-@cindex triplets
-Tuplets are made with the @code{\times} keyword. It takes two
-arguments: a fraction and a piece of music. The duration of the piece
-of music is multiplied by the fraction. Triplets make notes occupy 2/3
-of their notated duration, so in this case the fraction is 2/3.
-@example
-@{ <d8 \< f> <e g> <f a> @}
-@end example
-The piece of music to be `tripletted' is sequential music containing
-three notes. On the first chord, a crescendo is started with
-@code{\<}. To be precise, the crescendo start is syntactically attached
-to the preceding note, the @code{d}.
+@code{verbatim} also shows the LilyPond code, @code{11pt} selects
+the default music size, @code{fragment} adds a score block,
+@code{relative} uses relative mode for the fragment, and
+@code{intertext} specifies what to print between the
+@code{verbatim} code and the music.

-@cindex crescendo
-@cindex @code{\<}
+If you include large examples into the text, it may be more convenient

-@end example
-At this point, the homophonic music splits into two rhythmically
-different parts. We can't use a sequence of chords to enter this, so
-we make a `chord' of sequences to do it. We start with the upper
-voice, which continues with upward stems:
-@example
- @{ \times 2/3 @{ a8 g c @} \! c2 @}
-@end example
+@lilypondfile[printfilename]{sammartini.ly}

-The crescendo is ended at the half note by the escaped exclamation
-mark @code{\!}.
-@example
-\context Voice = oboeTwo @{
-\stemDown
-@end example
-We can't share stems with the other voice, so we have to create a new

-it from the other context. Stems go down in this voice.
-@example
-\grace @{
-@end example
-@cindex Grace context
-When a grace section is processed, a @code{Grace} context is
-created. This context acts like a miniature score of its own. It has
-its own time bookkeeping, and you can make notes, beams, slurs
-etc. Here we fiddle with a property and make a beam. The argument of
-@code{\grace} is sequential music.
-@example
-\property Grace.Stem \override #'direction = #-1
-[f,16 g] @}

-@cindex transposing
-@cindex relative mode and transposing
-Transposing can be done with @code{\transpose}. It takes two arguments;
-the first specifies what central C should be transposed to. The second
-is the to-be-transposed music. As you can see, in this case, the
-transposition is a no-op, as central C stay at central C.
+@c waar deze info? is uiteindelijk wel handig, schat ik.
+[TODO: cut blabla]
-The purpose of this no-op is circumventing relative mode. Relative mode
-can not be used together with transposition, so @code{\relative} will
-leave the contents of @code{\hoomPah} alone. We can use it without
-having to worry about getting the motive in a wrong octave.
-@example
-bassvoices = \notes \relative c' @{

-@cindex @code{\autochange}
+If you have a big music project, or just a lot of LilyPond input files,

+produce all output in the directory @file{out} , generate and track
+dependencies. Also, it helps in preparing your submission to @ref{Mutopia

-Voices can switch between staffs. The easiest way to get this, is to use
-@code{\autochange}. This command looks at the pitch of each note, and if
-necessary, will cross to the other staff. For this to work, the two
-staffs must be called @code{"up"} and @code{"down"}.
