Then you run LilyPond on the file. This leaves you with an output file, which you can view or print. In this section we explain how to run LilyPond, and view or print the output. If you want to test your setup of LilyPond, or try to run an example file yourself, then read this section. Otherwise, you can skip to the next section, which explains how to write LilyPond input. The instructions that follow are for Unix. Windows instructions are given at the end of this section. Start with opening a terminal window, and start up a text editor. For example, start an xterm and execute @code{joe}. Enter the following input, and save the file as @file{test.ly}. @example \score @{ \notes @{ c'4 e' g' @} @} @end example If this code looks intimidating you, then don't worry, we explain all about it in the next section. @cindex ly2dvi @c dit is dus raar, dat je ly2dvi draait om lelie te draaien @c (therefore name change proposal) Invoke the program @code{ly2dvi} to run lilypond on your source file: @example ly2dvi -P test @end example You will see the following on your screen: @example GNU LilyPond 1.4.0 Now processing: `/home/fred/ly/test.ly' Parsing... Interpreting music...[1] @emph{ ... more interesting stuff ... } PS output to `test.ps'... DVI output to `test.dvi'... @end example @cindex DVI file @cindex Viewing music @cindex xdvi The results of the ly2dvi run are two files, @file{test.dvi} and @file{test.ps}. The PS file (@file{test.ps}) is the one you can print. You can view the PS file using the program ghostview. If a version of ghostview is installed on your system, one of these commands will produce a window with some music notation on your screen. @example kghostview test.ps ggv test.ps ghostview test.ps gv test.ps @end example When you're satisfied with the result, you can print the PS file by clicking File/Print inside ghostview. The DVI file (@file{test.dvi}) contains the same sheet music in a different format. DVI files are more easily processed by the computer, so viewing them usually is quicker. Execute @code{xdvi test} to view the DVI file. If your DVI viewer does not have a "Print" button, you can print the file by executing @code{lpr test.ps}. @c volgende alinea schrappen? 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}. @cindex GhostScript @cindex @code{lpr} @cindex Printing output @cindex PostScript Windows users start the terminal by clicking on the lilypond icon. Notepad is sufficient for editing the lilypond file. Viewing the PS file can be done with @code{gsview32 test.ps}. Viewing DVI files can be done with @code{yap test}. The "print" button in Yap will print files. You can also print from the command line by executing @code{gsview32 /s test.ps} @c titel? @node First steps @section First steps Let's try to explain this example: The basics of any piece of music are notes.Notes are entered with letters @code{a} to @code{g} followed by a number that represents the duration: a @code{2} is a half note, a @code{4} is a quarter note. A period is used for augmentation dots, so entering @code{2.} gives a dotted half note. @example c2 e4 g2. @end example @lilypond[fragment] \property Score.timing = ##f \property Staff.TimeSignature = \turnOff \property Staff.Clef = \turnOff \clef bass c2 e4 g2. @end lilypond If you don't specify a duration, then the duration last entered is used: @c @example f4 e d c2. @end example @lilypond[fragment] \property Score.timing = ##f \property Staff.TimeSignature = \turnOff \property Staff.Clef = \turnOff \clef bass f4 e d c2. @end lilypond The time signature can be set with a command of the form @code{\time}, and the clef with @code{\clef} as follows: @example \time 3/4 \clef bass @end example @lilypond[fragment] \time 3/4 \clef bass s2._" " @end lilypond The commands together with the notes are combined to form a snippet of music. They are combined by enclosing them with @code{\notes @{ @}}. @example \notes @{ \time 3/4 \clef bass c2 e4 g2. f4 e d c2. @} @end example This snippet 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. The music and paper block are combined by enclosing them in @code{\score}. @lilypond[verbatim] \score { \notes { \time 3/4 \clef bass c2 e4 g2. f4 e d c2. } \paper { } } @end lilypond @ignore The @code{\paper} block looks empty, which means that we get default. That is because we did not contains page layout settings, such as the linewidth and the staff size. For now, we'll use standard settings, hence the paper block is empty (its braces enclose a blank space). @end ignore Rests are entered just like notes with the name @code{r} @lilypond[fragment,verbatim] r4 r8 r16 @end lilypond Octaves are entered by adding apostrophes or commas to note names. For example, the central C is entered as @code{c'}. Pitches can be octaviated by adding apostrophes or commas. The central C is @code{c'}. Going up octave by octave we get @code{c''}, @code{c'''}. Going down from central C, we get @code{c} @code{c,} @code{c,,} etc. @lilypond[verbatim,fragment] c'4 c'' c''' c c, @end lilypond LilyPond uses Dutch note names: you can make a note sharp by appending @code{is} to the name, and flat by appending @code{es} to the name. @lilypond[verbatim,fragment] fis'4 bes'4 aeses'4 @end lilypond Ties are created by entering a tilde (@code{~}) between the notes to be tied: @lilypond[fragment,verbatim] g'4 ~ g' a'2 ~ a'4 @end lilypond Ties look almost the same as slurs, but they are different. Ties can only indicate the extension of a note. Ties connect two note heads with the same pitch. Slurs on the other hand, can be drawn across many notes, and indicate bound articulation. The key signature is set with the command @code{\key}: @lilypond[fragment,verbatim] \key d \major g'1 \key c \minor g' @end lilypond The next example shows octave marks, ties, and rests in action. @lilypond[verbatim] \score { \notes { \time 4/4 \clef treble \key d \minor r4 r8 d''8 cis''4 e'' d''8 a'4. ~ a' b'8 cis''4 cis''8 cis'' bis'4 d''8 cis'' ~ cis''2 r2 } \paper { } } @end lilypond There is one interesting point to note in this example: accidentals don't have to be marked explicitly. You just enter the pitch, and LilyPond determines wether or not to print an accidental. Managing larger pieces. If you look at the last piece, it is already apparent that entering octaves using quotes is not very convenient. A score written in high register will be encoded using lots quotes. This makes the input file unreadable, and it also is a source of many errors. This problem is solved by relative octave mode. In this mode, the quotes are used to mark large jumps in the melody. Without any quotes or commas, the interval between a note and its predecessor is assumed to be a fourth or less. Quotes and commas add octaves in up and down direction. Relative octaves are introduced by @code{\relative} followed by a starting pitch @lilypond[fragment,verbatim] \relative c'' { c4 d4 b4 e4 a,4 f'4 g,4 a'4 } @end lilypond Slurs (not to be confused with ties) are entered with parentheses. You mark the starting note and ending note with a @code{(} and a @code{)} respectively. @lilypond[fragment,relative 2, verbatim] c8( cis d ) e @end lilypond If you need two slurs at the same time (one for articulation, one for phrasing), you can also make phrasing slurs with @code{\(} and @code{\)}. @c lousy example @lilypond[fragment,relative 1, verbatim] a8(\( ais b ) c cis2 b'2 a4 cis, \) c @end lilypond Beams are drawn automatically, but if you don't like the choices, you can enter beams by hand. Surround the notes to be grouped with @code{[} and @code{]}: @lilypond[fragment,relative 1, verbatim] [a8 ais] [d es r d] @end lilypond You can make more than one staff, by specifying @code{\context Staff} before snippets of music, and combining those snippets in @code{<} and @code{>}, as is demonstrated here: @lilypond[fragment,verbatim] < \context Staff = staffA { \clef treble c'' } \context Staff = staffB { \clef bass c } > @end lilypond Here, @code{staffA} and @code{staffB} are names that you give to the staff. For now, it doesn't matter what names you give, as long as they are different. We can typeset a melody with two staffs now: @lilypond[verbatim] \score { \notes < \context Staff = staffA { \time 3/4 \clef treble \relative c'' { e2 ( d4 c2 b4 [a8 a] [b b] [g g] )a2. } } \context Staff = staffB { \clef bass c2 e4 g2. f4 e d c2. } > \paper {} } @end lilypond 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 staffs. [TODO add some more here * \header * dynamics , articulation * * identifiers? ] This is the end of the simple tutorial. What follows is also a manual in tutorial-style, but it is much more in-depth, and alas more intimidating. You should read it if you want to know about the more advanced features of lilypond, such as producing orchestral scores and parts, fine tuning output, writing polyphonic music, etc. @node The first tune @section The first tune 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. 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 package. } To demonstrate what LilyPond input looks like, we start off with a full-fledged, yet simple example. It is a convoluted version of the famous minuet in J. S. Bach's @emph{Klavierb@"uchlein}. The file is included in the distribution as @file{minuet.ly}. @cindex Bach, Johann Sebastian @lilypond[verbatim] % all text after a percent sign is a comment % and is ignored by Lilypond \include "paper16.ly" \score { \notes \relative c'' \sequential { \time 3/4 \key g \major \repeat "volta" 2 { d4 g,8 a b c d4 g, g | e'4 c8 d e fis g4 g, g | c4 d8( )c b a( )b4 c8 b a g | a4 [b8 a] [g fis] g2. | } b'4 g8 a b g a4 d,8 e fis d | g4 e8 fis g d cis4 b8 cis a4 | a8-. b-. cis-. d-. e-. fis-. g4 fis e | fis a, r8 cis8 d2.-\fermata \bar "|." } \paper { % standard settings are too wide for a book linewidth = 14.0 \cm } } @end lilypond We will analyse the input, line by line. @separate @example % all text after a percent sign is a comment % and is ignored by Lilypond @end example The percent sign, @code{%}, introduces a line comment. You can also comment out a block of several lines, by enclosing them in @code{%@{} and @code{%@}}. @cindex comment @cindex block comment @cindex line comment @separate @example \include "paper16.ly" @end example @cindex @code{\include} @cindex point, printer's @cindex staff size setting By default, LilyPond will typeset the music in a size such that each staff is 20 point@footnote{A point is the standard measure of length for printing; one point is 1/72.27 inch.} high. We want smaller output (16 point staff height), so we must import the settings for that size, which is done here. @separate @example \score @{ @end example Music is printed by combining a piece of music with directions for outputting it. This combination is formed in the @code{\score} block. @separate @example \notes @end example Prepare LilyPond for accepting notes. @cindex octaves, choosing @cindex pitch @separate @example \relative c'' @end example @cindex relative As we will see, each note is described by its note name, duration, octave and possibly a chromatic alteration. In this setup, the octave is indicated by using high 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. Even though a piece of music often spans a range of several octaves, it mostly moves in small intervals. LilyPond has a special entry mode to save typing in this situation. In this ``relative'' octave mode, octaves of notes without quotes are chosen such that a note is as close as possible (graphically, on the staff) to the preceding note. If you add a high-quote an extra octave is added. A 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. @separate @example \sequential @{ @end example What follows is sequential music, i.e., @cindex sequential music notes that are to be played and printed after each other. @separate @example \time 3/4 @end example @cindex time signature, setting @cindex @code{\time} Set (or change) the time signature of the current piece: a 3/4 sign is printed. The time signature setting is also used to generate bar lines at the right spots. @separate @example \key g \major @end example @cindex key signature, setting @cindex @code{\key} Set (or change) the current key signature to G-major. Although in this example, the @code{\key} command happened to be entered after the @code{\time} command, in the output the time signature will be printed after the key signature; LilyPond knows about music typesetting conventions. @separate @example \repeat "volta" 2 @end example The following piece of music is played twice. The first argument indicates the type of repeat. In this case, @code{"volta"} means that prima volta/secunda volta brackets are used for the alternative endings---if there were any. @separate @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. @separate @example d4 g,8 @end example Two notes. The first note is a quarter note with relative pitch @code{d}. The relative music was started with a @code{c''}, so the real pitch of this note is @code{d''}. The duration of a note is designated by a number; the @code{4} here represents a quarter note. The second note is an eight note with relative pitch @code{g,}. The pitch is taken relative to the previous @code{d''}, making this note have real pitch @code{g'}. The @code{8} represents an eight note. @separate @example a b @end example Two more notes, with pitch @code{a} and @code{b}. Because their duration is the same as the @code{g,8}, there is no need to enter the duration, but you may enter it anyway, i.e., @code{a4 b4} @separate @example d4 g, g | @end example @cindex bar check @cindex @code{|} @cindex errors, finding Three more notes. The @code{|} character is a ``bar check''. LilyPond will verify that bar checks are found at the start of a measure. This can help you track down typing errors. @cindex alteration, chromatic @cindex chromatic alteration @separate @example c8 d e fis @end example So far, no notes were chromatically altered. Here is the first one that is: @code{fis}. Lilypond by default uses Dutch@footnote{Note names are available in several languages, but we find the Dutch names quite convenient.} 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. For groups of eighth notes and shorter, LilyPond can determine how the notes should form a beam. In this case, the 4 eights are automatically printed as a beam. @separate @example c4 d8( )c b a( )b4 c8 b a g | @end example The beginning and ending notes of a slur are marked with parentheses, @code{(} and @code{)} for start and end respectively. The line above indicates two slurs. These slur markers (parentheses) are entered between the slurred notes. @separate @example a4 [b8 a] [g fis] @end example Automatic beaming can be overridden by inserting beam marks, @code{[} and @code{]}. These beam markers (brackets) are put around the notes you want beamed. @separate @example g2. | @end example @cindex augmentation dot @cindex dot A period adds an augmentation dot to the note. @separate @example @} @end example The end of the sequential music to be repeated. LilyPond will typeset a repeat bar. @separate @example cis'4 b8 cis a4 | @end example Accidentals are printed whenever necessary: the first C sharp of the bar will be printed with an accidental, the second one without. @separate @example a8-. b-. cis-. d-. e-. fis-. @end example @cindex articulation You can enter articulation signs either in a verbose form or using a shorthand. Here we demonstrate the shorthand: it is formed by a dash and the character for the articulation to use, e.g. @code{-.} for staccato as shown above. @separate @example fis a, r8 cis8 @end example Rests are denoted by the special notename @code{r}. @separate @example d2.-\fermata @end example All articulations have a verbose form, like @code{\fermata}. The command @code{\fermata} is not part of the core of the language, but it is a shorthand for a more complicated description of a fermata symbol. @code{\fermata} names that description and is therefore called an identifier. @cindex identifier @cindex @code{\fermata} @separate @example \bar "|." @} @end example Here the music ends. LilyPond does not automatically typeset and end bar, we must explicitely request one, using @code{"|."}. @separate @example \paper @{ linewidth = 14.0\cm @} @end example The @code{\paper} block specifies how entered music should be converted to notation output. Most of the details of the conversion (font sizes, dimensions, etc.) have been taken care of, but to fit the output in this document, it has to be narrower. We do this by setting the line width to 14 centimeters (approximately 5.5 inches). @separate @example @} @end example The last brace ends the @code{\score} block. @node Lyrics and chords @section Lyrics and chords In this section we show how to typeset a song. This file is included as @file{flowing.ly}. @example \header @{ title = "The river is flowing" composer = "Traditional" @} \include "paper16.ly" melody = \notes \relative c' @{ \partial 8 \key c \minor g8 | c4 c8 d [es () d] c4 | f4 f8 g [es() d] c g | c4 c8 d [es () d] c4 | d4 es8 d c4. \bar "|." @} text = \lyrics @{ The ri -- ver is flo- __ wing, flo -- wing and gro -- wing, the ri -- ver is flo -- wing down to the sea. @} accompaniment =\chords @{ r8 c2:3- f:3-.7 d:min es4 c8:min r8 c2:min f:min7 g:7^3.5 c:min @} \score @{ \simultaneous @{ %\accompaniment \context ChordNames \accompaniment \addlyrics \context Staff = mel @{ \property Staff.noAutoBeaming = ##t \property Staff.automaticMelismata = ##t \melody @} \context Lyrics \text @} \midi @{ \tempo 4=72 @} \paper @{ linewidth = 10.0\cm @} @} @end example The result would look this.@footnote{The titling and font size shown may differ, since the titling in this document is not generated by @code{ly2dvi}.} @center @strong{The river is flowing} @center Traditional @lilypond[center] \header { title = "The river is flowing" composer = "Traditional" } \include "paper16.ly" melody = \notes \relative c' { \partial 8 \key c \minor g8 | c4 c8 d [es () d] c4 | f4 f8 g [es() d] c g | c4 c8 d [es () d] c4 | d4 es8 d c4. \bar "|." } text = \lyrics { The ri -- ver is flo- __ wing, flo -- wing and gro -- wing, the ri -- ver is flo -- wing down to the sea. } accompaniment =\chords { r8 c2:3- f:3-.7 d:min es4 c8:min r8 c2:min f:min7 g:7^3.5 c:min } \score { \simultaneous { %\accompaniment \context ChordNames \accompaniment \addlyrics \context Staff = mel { \property Staff.noAutoBeaming = ##t \property Staff.automaticMelismata = ##t \melody } \context Lyrics \text } \midi { \tempo 4=72 } \paper { linewidth = 10.0\cm } } @end lilypond Again, we will dissect the file line by line. @separate @example \header @{ @end example @cindex @code{\header} Information about the music you are about to typeset goes into a @code{\header} block. The information in this block is not used by LilyPond, but it is passed into the output. @file{ly2dvi} uses this information to print titles above the music. @separate @example title = "The river is flowing" composer = "Traditional (?)" @end example @cindex assignments @cindex identifier assignment the @code{\header} block contains assignments. In each assignment, a variable is set to a value. Lexically, both the variable name and the assigned value are strings. The values have to be quoted here, because they contain spaces, the variable names could also be put within quotes but it is not necessary. @separate @example \include "paper16.ly" @end example Smaller size for inclusion in a book. @separate @example melody = \notes \relative c' @{ @end example The structure of the file will be the same as the previous one, a @code{\score} block with music in it. To keep things readable, we will give names to the different parts of music, and use the names to construct the music within the score block. @separate @example \partial 8 @end example @cindex @code{\partial} @cindex anacrusis The piece starts with an anacrusis of one eighth. @separate @example \key c \minor @end example The key is C minor: we have three flats. @separate @example c4 c8 d [es () d] c4 | f4 f8 g [es() d] c g | c4 c8 d [es () d] c4 | d4 es8 d c4. \bar "|." @end example @cindex manual beaming @cindex automatic beaming, turning off We use explicit beaming. Since this is a song, we turn automatic beams off, and use explicit beaming where needed. @separate @example @} @end example This ends the definition of @code{melody}. @separate @example text = \lyrics @{ @end example @cindex lyrics @cindex identifier assignment @cindex syllables, entering Another identifier assignment. This one is for the lyrics. Lyrics are formed by syllables that have duration, and not by notes. To make LilyPond parse words as syllables, switch it into lyrics mode with @code{\lyrics}. Again, the brace after @code{\lyrics} is a shorthand for @code{\sequential @{}. @separate @example The4 ri -- ver is flo- __ wing, flo -- wing and gro -- wing, the ri- ver is flo- __ wing down to the sea. @} @end example @cindex extenders, lyric @cindex hyphens, lyric The syllables themselves are separated by spaces. You can get syllable extenders by entering @code{__}, and centered hyphens with @code{-}@code{-}. We enter the syllables as if they are all quarter notes in length (hence the @code{4}), and use a feature to align the syllables to the music, which obviously isn't all quarter notes. @separate @example accompaniment =\chords @{ @end example @cindex chords @cindex mode, chords We'll put chords over the music. To enter them, there is a special mode analogous to @code{\lyrics} and @code{\notes} mode, where you can give the names of the chords you want, instead of listing the notes comprising the chord. @separate @example r8 @end example There is no accompaniment during the anacrusis. @separate @example c2:3- f:3-.7 @end example @cindex tonic @cindex chord modifier @cindex modifier, chord A chord is started by the tonic of the chord. The first one lasts a half note. An unadorned note creates a major triad. Since a minor triad is wanted, @code{3-} is added to modify the third to be small. @code{7} modifies (adds) a seventh, which is small by default to create the @code{f a c es} chord. Multiple modifiers must be separated by dots. @separate @example d:min es4 c8:min r8 @end example Some modifiers have predefined names, eg. @code{min} is the same as @code{3-}, so @code{d-min} is a minor @code{d} chord. @separate @example c2:min f:min7 g:7^3.5 c:min @} @end example @cindex named modifier A named modifier @code{min} and a normal modifier @code{7} do not have to be separated by a dot. Tones from a chord are removed with chord subtractions. Subtractions are started with a caret, and they are also separated by dots. In this example, @code{g:7^3.5} produces a minor seventh. The brace ends the sequential music. @separate @example \score @{ \simultaneous @{ @end example We assemble the music in the @code{\score} block. Melody, lyrics and accompaniment have to sound at the same time, so they should be @code{\simultaneous}. @cindex @code{\simultaneous} @separate @example %\accompaniment @end example Chord mode generates notes grouped in @code{\simultaneous} music. If you remove the comment sign, you can see the chords in normal notation: they will be printed as note heads on a separate staff. To print them as chords names, they have to be interpreted as being chords, not notes. This is done with the following command: @separate @example \context ChordNames \accompaniment @end example @cindex context @cindex interpretation context @cindex notation context 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. By default, LilyPond will create a Staff context for you. If you would remove the @code{%} sign in the previous line, you would see that mechanism in action. We don't want that default here, because we want chord names. The command above explicitly creates an interpretation context of @code{ChordNames} type to interpret the music @code{\accompaniment}. @separate @example \addlyrics @end example @cindex @code{\addlyrics} @cindex lyrics and melody, combining @cindex combining lyrics and melody The lyrics should be aligned with the melody. This is done by combining both with @code{\addlyrics}. @code{\addlyrics} takes two pieces of music (usually a melody and lyrics, in that order) and aligns the syllables of the second piece under the notes of the first piece. If you would reverse the order, the notes would be aligned on the lyrics, which is not very useful, and looks silly. @separate @example \context Staff = mel @{ @end example The second argument of @code{\addlyrics} is the melody. We instantiate a @code{Staff} context explicitly: should you choose to remove the comment before the ``note heads'' version of the accompaniment, the accompaniment will be on a nameless staff. The melody has to be on staff different from the accompaniment. This is accomplished by giving the melody and accompaniment staffs different names. @separate @example \property Staff.noAutoBeaming = ##t @end example @cindex \property @cindex context variables @cindex setting context variables An interpretation context has variables, called properties, that tune its behaviour. One of the variables is @code{noAutoBeaming}. Setting this Staff's property to @code{##t}, which is the boolean value @var{true}, turns the automatic beaming mechanism off for the current staff. @cindex GUILE @cindex Scheme @cindex accessing Scheme @cindex evaluating Scheme @cindex LISP LilyPond internally uses GUILE, a Scheme-interpreter. Scheme is a language from the LISP family. You can learn more about Scheme at @uref{http://www.scheme.org}. It is used to represent data throughout the whole program. The hash-sign (@code{#}) accesses GUILE directly: the code following the hash-sign is evaluated as Scheme. The boolean value @var{true} is @code{#t} in Scheme, so for LilyPond @var{true} looks like @code{##t}. If Scheme scares you, don't worry. You don't need to know Scheme to create beautiful sheet music. @separate @example \property Staff.automaticMelismata = ##t @end example @cindex automaticMelismata @cindex melismata @cindex @code{\addlyrics} and slurs Similarly, we don't want to print a syllable when there is a slur. This sets up @code{\addlyrics} to not put lyrics under each separate note while there is a slur. @separate @example \melody @} @end example Finally, we put the melody on the current staff. Note that the @code{\property} directives and @code{\melody} are grouped in sequential music, so the property settings are done before the melody is processed. @separate @example \context Lyrics \text @end example The second argument of @code{\addlyrics} is the text. The text also should not land on a Staff, but on a interpretation context for syllables, extenders, hyphens etc. This context is called Lyrics. @separate @example \midi @{ \tempo 4=72@} @end example MIDI (Musical Instrument Digital Interface) is a standard for connecting and recording digital instruments. So a MIDI file is like a tape recording of an instrument. The @code{\midi} block causes makes the music go to a MIDI file, so you can listen to the music you entered. It is great for checking the music. Whenever you hear something weird, you probably hear a typing error. Syntactically, @code{\midi} is similar to @code{\paper @{ @}}, since it also specifies an output method. You can specify the tempo using the @code{\tempo} command, in this case the tempo of quarter notes is set to 72 beats per minute. @separate @example \paper @{ linewidth = 10.0\cm @} @end example We also want notation output. The linewidth is short so the piece will be set in two lines. @node More movements @section More movements [FIXME: merge here with, or move this to: Other ways to run LilyPond] You probably ran @file{ly2dvi} on the last example, and ended up with a viewable @file{.dvi} file. However, between there are a few steps of which LilyPond is only one. To enhance your understanding of what's happening under the hood when you run @code{ly2dvi}, we explain what programs are run. @code{ly2dvi} is a program that calls a number of programs in sequence. The first thing it does, is running LilyPond on the input file. After some calculations, a @file{.tex} is produced. The contents of this file are very low-level instructions. For example, the following file (@file{miniatures.ly}) @example \version "1.3.124" \header @{ title = "Two miniatures" @} #(set! point-and-click line-column-location) \paper @{ linewidth = -1.0 @} \score @{ \notes @{ c'4 d'4 @} \header @{ opus = "Opus 1." piece = "Up" @} @} \score @{ \notes @{ d'4 c'4 @} \header @{ opus = "Opus 2." piece = "Down" @} @} @end example The titling in this manual was not generated by ly2dvi, so we can't exactly show it would look, but the result should resemble this: @center @strong{Two miniatures} @flushright Opus 1. @end flushright @flushleft @var{Up} @end flushleft @lilypond \score { \notes { c'4 d'4 } \paper { linewidth = -1.0 } } @end lilypond @flushright Opus 2. @end flushright @flushleft @var{Down} @end flushleft @lilypond \score { \notes { d'4 c'4 } \paper { linewidth = -1.0 } } @end lilypond This file is produced by ly2dvi in a few stages, with the help of text formatting tools. LilyPond produces two output files, @file{miniatures.tex} and @file{miniatures-1.tex}. They both look like this: @example ... \placebox@{-5 \outputscale @}% @{ 8.7229 \outputscale @}% @{\magfontWXGEomMMBo\char90 @}% \placebox@{-4 \outputscale @}% @{ 81.0647 \outputscale @}% ... @end example @file{ly2dvi} looks at what output LilyPond produces, and generates a file called @file{ly2dvi.out.tex}. This file contains formatting instructions for the title and page layout. A fragment might look like @example \def\lilypondopus@{Opus 1.@} \def\lilypondpiece@{Up@} \def\mustmakelilypondtitle@{@} \input miniatures.tex \def\lilypondtitle@{Two miniatures@} @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 the actual music. @code{ly2dvi} completes its task by deleting the two temporary files, leaving only @file{miniatures.dvi}. Next, now we'll look at the example line by line to explain new things. @separate @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. This version number is also used by the @code{convert-ly} program (See @ref{convert-ly}), which uses it to update the file to the latest lily version. @separate @example \header @{ title = "Two miniatures" @} @end example This sets the titling information for the entire file. @separate @example #(set! point-and-click line-column-location) @end example 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). 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 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}. @separate @example \paper @{ @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. @separate @example linewidth = -1.0 @} @end example The variable @code{linewidth} normally sets the length of the systems on the page. However, a negative value has a special meaning. If @code{linewidth} is less than 0, no line breaks are inserted into the score, and the spacing is set to natural length: a short phrase takes up little space, a longer phrase more space. @separate @example \score @{ \notes @{ c'4 d'4 @} @end example 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, which you get when you don't specify @code{\relative}. 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. 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 \header @{ @end example 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 an exercise 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" @} @end example For example, the Opus number is put at the right, and the piece string will be at the left. @node A piano excerpt @section A piano excerpt Our fourth subject is a piece of piano music. The fragment in the input file is a piano reduction of the G major Sinfonia by Giovanni Battista Sammartini. It was composed around 1740. It's in the source package under the name @file{sammartini.ly}. @lilypond[verbatim] \include "paper16.ly" stemDown = \property Voice.Stem \override #'direction = #-1 stemUp = \property Voice.Stem \override #'direction = #1 stemBoth = \property Voice.Stem \revert #'direction viola = \notes \relative c' \context Voice = viola { \stemDown g'8. b,16 s1 s2. r4 g } oboes = \notes \relative c'' \context Voice = oboe { \stemUp s4 g8. b,16 c8 r \grace \times 2/3 { } < { \times 2/3 { a8 g c } \! c2 } \context Voice = oboeTwo { \stemDown \grace { \property Grace.Stem \override #'direction = #-1 [f,16 g] } f8 e e2 } > \stemBoth \grace <)b8. d8.-\trill> | [ < )f8. a>] <)b,8 d> r [ ] r | [ < )e8. g>] } hoomPah = \repeat unfold 8 \notes \transpose c' { \stemUp c8 \stemBoth \stemDown c'8 \stemBoth } bassvoices = \notes \relative c' { c4 g8. b,16 \autochange Staff \hoomPah \translator Staff = down \stemDown [c8 c'8] r4 r4 < {\stemUp r2 } \context Voice = reallyLow {\stemDown g2 ~ | g4 c8 } > } \score { \context PianoStaff \notes < \context Staff = up < \time 2/2 \viola \oboes > \context Staff = down < \time 2/2 \clef bass \bassvoices > > \midi { } \paper { indent = 0.0 linewidth = 15.0 \cm } } @end lilypond If this looks like incomprehensible gibberish to you, you are right. This example has been doctored to have as many quirks as possible. As you can see, this example features multiple voices on one staff. To make room for those voices, their notes have to be stemmed in opposite directions. Printed symbols are internally represented by so-called Graphical Objects (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}. @separate @example stemDown = \property Voice.Stem \override #'direction = #-1 @end example Set a proprerty 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 \property Voice.Stem \revert #'direction @end example Revert the to the previous setting. The effect of precisely one @code{\stemDown} or @code{\stemUp} is neutralised. LilyPond includes the identifiers @code{\stemUp}, @code{\stemDown} along with some other commonly 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. @separate @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}'). @separate @example @end example The delimiters @code{<} and @code{>} are shorthands for @code{\simultaneous @{} and @code{@}}. The expression enclosed in @code{<} and @code{>} is a chord. @cindex dynamics @cindex loudness @cindex forte @cindex arpeggio @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. @code{\arpeggio} typesets an arpeggio sign (a wavy vertical line) before the chord. @separate @example \stemDown @end example @separate @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). @separate @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. @separate @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}. @separate @example \stemUp s4 g8. b,16 c8 r @end example @code{\stemUp} is a reference to the @code{\property \override} command defined above. @separate @example \grace < d4 f> @end example @cindex @code{\grace} @cindex ornaments @cindex grace notes @code{\grace} introduces grace notes. It takes one argument, in this case a chord. @ignore The slur started on the @code{e} of the chord will be attached to the next note.@footnote{LilyPond will squirm about unended Slurs. In this case, you can ignore the warning}. @end ignore @separate @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. @separate @example @{ @} @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}. @cindex dynamics @cindex crescendo @cindex @code{\<} @separate @example < @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: @separate @example @{ \times 2/3 @{ a8 g c @} \! c2 @} @end example @cindex @code{\!} The crescendo is ended at the half note by the escaped exclamation mark @code{\!}. @separate @example \context Voice = oboeTwo @{ \stemDown @end example We can't share stems with the other voice, so we have to create a new @code{Voice} context. We give it the name @code{oboeTwo} to distinguish it from the other context. Stems go down in this voice. @separate @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. @separate @example \property Grace.Stem \override #'direction = #-1 [f,16 g] @} @end example Normally, grace notes are always stem up, but in this case, the upper voice interferes. We set the stems down here. As far as relative mode is concerned, the previous note is the @code{c'''2} of the upper voice, so we have to go an octave down for the @code{f}. @separate @example f8 e e2 @} > @end example This ends the two-part section. @separate @example \stemBoth \grace <)b8. d8.-\trill> | @end example @cindex trill @cindex stemBoth @code{\stemBoth} ends the forced stem directions. From here, stems are positioned as if it were single part music. The bass has a little hoom-pah melody to demonstrate parts switching between staffs. Since it is repetitive, we use repeats: @separate @example hoomPah = \repeat unfold 8 @end example @cindex unfolded @code{\repeat} The unfolded repeat prints the notes in its argument as if they were written out in full eight times. @separate @example \notes \transpose c' @{ @end example @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 has no effect, as central C stays at central C. 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. @separate @example bassvoices = \notes \relative c' @{ c4 g8. b,16 \autochange Staff \hoomPah @end example @cindex staff switch, automatic @cindex cross staff voice, automatic @cindex @code{\autochange} 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"}. @separate @example \translator Staff = down @end example @cindex staff switch @cindex cross staff voice We want the remaining part of this melody on the lower staff, so we do a manual staff switch here. @separate @example \context Voice = reallyLow @{\stemDown g2 ~ | g4 c8 @} > @end example @cindex tie @cindex @code{~} After skipping some lines, we see @code{~}. This mark makes ties. Note that ties and slurs are different things. A tie can only connect two note heads of the same pitch, whereas a slur can connect many chords with one curve. @separate @example \context PianoStaff @end example A special context is needed to get cross staff beaming right. This context is called @code{PianoStaff}. @separate @example \context Staff = bottom < \time 2/2 \clef bass @end example The bottom staff must have a different clef. @separate @example indent = 0.0 @end example To make some more room on the line, the first (in this case the only) line is not indented. The line still looks very cramped, but that is due to the page layout of this document. @ignore [TODO: * font-size, multi-stanza. * Simple part combining in a Hymn @end ignore @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. 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" @} global = @{ \time 2/4 \skip 2*4 \bar "|." @} Key = \notes \key as \major flautoI = \notes\relative c'' @{ f8 g f g f g f g bes as bes as bes as bes as @} flautoII = \notes\relative c'' @{ as8 bes as bes R1 d4 ~ d @} tromboI = \notes\relative c'' @{ c4. c8 c8 c4. es4 r as, r @} tromboII = \notes\relative c'' @{ as4. as8 as8 as4.

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 @end example Declare the key signature of the piece and assign it to the identifier @var{Key}. Lateron, we'll use @code{\Key} for all staffs except those for transposing instruments. @node The full score @subsection The full score The second file, @file{os-score.ly} reads the definitions of the first (@file{os-music.ly}), and defines the @code{\score} block for the full conductor's score. @example % os-score.ly \include "os-music.ly" \include "paper13.ly" #(set! point-and-click line-column-location) #(define text-flat '((font-relative-size . -2) (music "accidentals--1"))) \score @{ < \global \property Score.BarNumber \override #'padding = #3 \context StaffGroup = woodwind < \context Staff = flauti < \property Staff.midiInstrument = #"flute" \property Staff.instrument = "2 Flauti" \property Staff.instr = "Fl." \Key \context Voice=one @{ \voiceOne \flautoI @} \context Voice=two @{ \voiceTwo \flautoII @} > > \context StaffGroup = timpani < \context Staff = timpani < \property Staff.midiInstrument = #"timpani" \property Staff.instrument = #'(lines "Timpani" "(C-G)") \property Staff.instr = #"Timp." \clef bass \Key \timpani > > \context StaffGroup = brass < \context Staff = trombe < \property Staff.midiInstrument = #"trumpet" \property Staff.instrument = #`(lines "2 Trombe" "(C)") \property Staff.instr = #`(lines "Tbe."

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 sharp sign is called @code{accidentals-+1}). The default font is too big for text, so we select a relative size of @code{-2}. @separate @example < \global @end example Of course, all staffs are simultaneous and use the same global settings. @separate @example \property Score.BarNumber \override #'padding = #3 @end example 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. You can find all this kind of information in LilyPond's automatically generated documentation in @ifnottex @ref{ (lilypond-internals)lilypond-internals, LilyPond Internals}. @end ifnottex @iftex the online documentation. @end iftex @separate @example \context StaffGroup = woodwind < \context Staff = flauti < @end example A new notation context: the StaffGroup. StaffGroup can hold one or more Staffs, and will print a big bracket at the left of the score. Start a new staff group for the woodwind section (just the flutes in this case). Immediately after that, we start the staff for the two flutes, that also play simultaneously. @separate @example \property Staff.midiInstrument = #"flute" @end example Specify the instrument for MIDI output (see @ref{MIDI instrument names}). @separate @example \property Staff.instrument = "2 Flauti" \property Staff.instr = "Fl." @end example And define the instrument names to be printed in the margin, @code{instrument} for the first line of the score, @code{instr} for the rest of the score. @separate @example \Key @end example The flutes play in the default key. @separate @example \context Voice=one @{ \voiceOne \flautoI @} \context Voice=two @{ \voiceTwo \flautoII @} @end example Last come the actual flute parts. Remember that we're still in 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. @separate @example > > @end example Close the flutes staff and woodwind staff group. @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. @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 two elements (columns), the @code{E} and the flat sign @code{text-flat} that we defined before. @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 proprerty @var{transposing}. @separate @example \notes \key bes \major @end example Therefore, it has a different key. @separate @example indent = 15 * \staffspace linewidth = 60 * \staffspace @end example 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. In orchestral scores, it often happens that one instrument has only rests during one line of the score. The @code{HaraKiriStaffContext} can be used as a regular @code{StaffContext} drop-in and will take care of the automatic removing of empty staffs. @node Extracting an individual part @subsection Extracting an individual part The third file, @file{os-flute-2.ly} also reads the definitions of the first (@file{os-music.ly}), and defines the @code{\score} block for the second flute part. @example \include "os-music.ly" \include "paper16.ly" \score @{ \context Staff < \property Score.skipBars = ##t \property Staff.midiInstrument = #"flute" \global \Key \flautoII > \header @{ instrument = "Flauto II" @} \paper @{ linewidth = 80 * \staffspace textheight = 200 * \staffspace @} \midi @{ \tempo 4 = 75 @} @} @end example @center @strong{Zo, goed lieverd?} @sp 1 @center How's, this babe? @center @emph{Flauto II} @flushright Opus 1. @end flushright @flushleft @sc{Laid back} @end flushleft @lilypondfile{os-flute-2.ly} Because we separated the music definitions from the @code{\score} instantiations, we can easily define a second score from 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 \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. @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 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. @node Other ways to run LilyPond @section Other ways to run LilyPond Until now, you have been using @file{ly2dvi} to invoke LilyPond. There are three other routes. Firstly, there is a script called @code{lilypond-book}, that allows you to freely mix LilyPond input with Texinfo or LaTeX input. For example, this manual was written using @code{lilypond-book}. It is discussed in @ref{lilypond-book}. Secondly, you can generate PostScript directly. This is useful if you can not or do not want to run @TeX{} on your system. To obtain direct PostScript output, invoke LilyPond as follows: @cindex PostScript output @example lilypond -f ps test.ly @end example You have to set some environment variables to view or print this output. More information can be found in @ref{Invoking LilyPond}. Thirdly, if you want to do special things with your output, you can run invoke lilypond directly: @example lilypond test.ly @end example to produce plain @TeX{} output. Note that La@TeX{} will not work on the resulting @file{test.tex}. You must run plain @TeX{} on it. @cindex @TeX{} @node Integrating text and music @section Integrating text and music 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: If you use 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. lilypond-book is described fully in @ref{lilypond-book}, but here we show a small example. Since the example also contains explanatory text, we won't comment on the contents. @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 Under Unix, you can view the results as follows. @example $ cd input/tutorial $ lilypond-book --outdir=out/ lilbook.tex lilypond-book (GNU LilyPond) 1.3.146 Reading `/home/hanwen/usr/src/lilypond-1.3.146/input/tutorial/lilbook.tex' Reading `/home/hanwen/usr/src/lilypond-1.3.146/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 Notice the @code{outdir} option to lilypond-book. Running lilypond-book and running latex creates a lot of temporary files, and you wouldn't those to clutter up your working directory. Hence, we have them created in a separate subdirectory. The result more or less looks like this: @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. If you have no @code{\score} block in the fragment, @code{lilypond-book} will supply one: @lilypond c'4 @end lilypond In the example you see here, a number of things happened: a @code{\score} block was added, and the line width was set to natural length. You can specify many more options using La@TeX{} style options in brackets: @lilypond[verbatim,11pt,singleline, fragment,relative,intertext="hi there!"] c'4 f bes es @end lilypond @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. 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 @code{printfilename} option adds the file name to the output. @node end of tutorial @section The end That's all folks. From here, you can either try fiddling with input files, or you can read the reference manual. You can find more example files in @file{input} and @file{input/test}. You can also look at some real music. Have a look at the @uref{Mutopia project, http://www.mutopiaproject.org}. @ignore [TODO this should be on mutopia website. ] @c waar deze info? is uiteindelijk wel handig, schat ik. [TODO: cut blabla] If you have a big music project, or just a lot of LilyPond input files, all generated output from LilyPond, @TeX{} and metafont will clutter your working directory. LilyPond comes with a one-size-fits-all pre-cooked makefile that helps you manage producing output. It will produce all output in the directory @file{out} , generate and track dependencies. Also, it helps in preparing your submission to @ref{Mutopia project}. @file{make/ly.make} @example mkdir my-project cd my-project cp /usr/share/lilypond/make/ly.make GNUmakefile cp /usr/share/doc/lilypond/examples/input/tutorial/minuet.ly . make minuet [..] Generated out/minuet.ps for target minuet. @end example Type @samp{make help} to see possible targets.
