@subheading Warning: key signatures and pitches

Music Glossary: @rglos{accidental}, @rglos{key signature},
@rglos{pitch}, @rglos{flat}, @rglos{natural}, @rglos{sharp},
@rglos{transposition}.

To determine whether to print an @notation{accidental}, LilyPond
examines the pitches and the @notation{key signature}.  The key
signature only affects the @emph{printed} accidentals, not the
note's @notation{pitch}!  This is a feature that often causes
confusion to newcomers, so let us explain it in more detail.

LilyPond makes a sharp distinction between musical content and
layout.  The alteration (@notation{flat}, @notation{natural sign} or
@notation{sharp}) of a note is part of the pitch, and is therefore
musical content.  Whether an accidental (a @emph{printed} flat,
natural or sharp sign) is printed in front of the corresponding
note is a question of layout.  Layout is something that follows
rules, so accidentals are printed automatically according to those
rules.  The pitches in your music are works of art, so they will
not be added automatically, and you must enter what you want to
hear.

In this example:

@lilypond[verbatim,quote,relative=2]
\key d \major
d cis fis
@end lilypond

@noindent
No note has a printed accidental, but you must still add
@code{is} and type @code{cis} and @code{fis} in the input file.

The code @code{b} does not mean @qq{print a black dot just on
the middle line of the staff.}  Rather, it means @qq{there is a
note with pitch B-natural.}  In the key of A-flat major, it
@emph{does} get an accidental:

@lilypond[verbatim,quote,relative=2]
\key aes \major
b
@end lilypond

If the above seems confusing, consider this: if you were playing a
piano, which key would you hit?  If you would press a black key,
then you @emph{must} add @code{-is} or @code{-es} to the note
name!

Adding all alterations explicitly might require a little more
effort when typing, but the advantage is that
@notation{transposing} is easier, and accidentals can be printed
according to different conventions.  For some examples of how
accidentals can be printed according to different rules, see
@ruser{Automatic accidentals}.

than one voice on the same staff.

@node Music expressions explained
@subsection Music expressions explained

@cindex music expression
@cindex expression, music
@cindex compound music expression
@cindex music expression, compound

In LilyPond input files, music is represented by @emph{music
expressions}.  A single note is a music expression:

@lilypond[verbatim,quote,relative=2]
a4
@end lilypond

Enclosing a note in braces creates a @emph{compound music
expression}.  Here we have created a compound music expression
with two notes:

@lilypond[verbatim,quote,relative=2]
{ a4 g4 }
@end lilypond

Putting a group of music expressions (e.g. notes) in braces means
that they are in sequence (i.e. each one follows the previous
one).  The result is another music expression:

@lilypond[verbatim,quote,relative=2]
{ { a4 g } f g }
@end lilypond

@subheading Analogy: mathematical expressions

This mechanism is similar to mathematical formulas: a big formula
is created by composing small formulas.  Such formulas are called
expressions, and they can contain other expressions, so you can
make arbitrarily complex and large expressions.  For example,

@example
1

1 + 2

(1 + 2) * 3

((1 + 2) * 3) / (4 * 5)
@end example

This is a sequence of expressions, where each expression is
contained in the next (larger) one.  The simplest expressions are
numbers, and larger ones are made by combining expressions with
operators (like @code{+}, @code{*} and @code{/}) and parentheses.
Like mathematical expressions, music expressions can be nested
arbitrarily deep, which is necessary for complex music like
polyphonic scores.

@funindex <<
@funindex >>
@funindex << ... >>

Music Glossary: @rglos{polyphony}.

This technique is useful for @notation{polyphonic} music.  To
enter music with more voices or more staves, we combine
expressions in parallel.  To indicate that two voices should play
at the same time, simply enter a simultaneous combination of music
expressions.  A @q{simultaneous} music expression is formed by
enclosing expressions inside @code{<<} and @code{>>}.  In the
following example, three sequences (all containing two separate
notes) are combined simultaneously:

@lilypond[verbatim,quote]
\relative c'' {
  <<
    { a4 g }
    { f e }
    { d b }
  >>
}
@end lilypond

Note that we have indented each level of the input with a
different amount of space.  LilyPond does not care how much (or
little) space there is at the beginning of a line, but indenting
LilyPond code like this makes it much easier for humans to read.

@warning{each note is relative to the previous note in
the input, not relative to the @code{c''} in the initial
@code{@bs{}relative} command.}


@subheading Simultaneous music expressions: single staff

To determine the number of staves in a piece, LilyPond looks at
the beginning of the first expression.  If there is a single note,
there is one staff; if there is a simultaneous expression, there
is more than one staff.  The following example shows a complex
expression, but as it begins with a single note it will be set
out on a single staff.

@lilypond[verbatim,quote]
\relative c'' {
  c2 <<c e>>
  << { e f } { c <<b d>> } >>
}
@end lilypond

@funindex ChordNames

LilyPond input files are constructed out of music expressions, as
we saw in @ref{Music expressions explained}.  If the score begins
with simultaneous music expressions, LilyPond creates multiples
staves.  However, it is easier to see what happens if we create
each staff explicitly.

To print more than one staff, each piece of music that makes up a
staff is marked by adding @code{\new Staff} before it.  These
@code{Staff} elements are then combined in parallel with @code{<<}
and @code{>>}:

@lilypond[verbatim,quote]
\relative c'' {
  <<
    \new Staff { \clef treble c }
    \new Staff { \clef bass c,, }
  >>
}
@end lilypond

The command @code{\new} introduces a @q{notation context.}  A
notation context is an environment in which musical events (like
notes or @code{\clef} commands) are interpreted.  For simple
pieces, such notation contexts are created automatically.  For
more complex pieces, it is best to mark contexts explicitly.

There are several types of contexts.  @code{Score}, @code{Staff},
and @code{Voice} handle melodic notation, while @code{Lyrics} sets
lyric texts and @code{ChordNames} prints chord names.

In terms of syntax, prepending @code{\new} to a music expression
creates a bigger music expression.  In this way it resembles the
minus sign in mathematics.  The formula @math{(4+5)} is an
expression, so @math{-(4+5)} is a bigger expression.

Time signatures entered in one staff affect all other staves by
default.  On the other hand, the key signature of one staff does
@emph{not} affect other staves.  This different default behavior
is because scores with transposing instruments are more common
than polyrhythmic scores.

@lilypond[verbatim,quote]
\relative c'' {

    \new Staff { \clef treble \key d \major \time 3/4 c }
    \new Staff { \clef bass c,, }

Music Glossary: @rglos{brace}.

Piano music is typeset in two staves connected by a
@notation{brace}.
Printing such a staff is similar to the polyphonic example in
@ref{Multiple staves}.  However, now this entire expression is
inserted inside a @code{PianoStaff}:

@example
\new PianoStaff <<
  \new Staff @dots{}
  \new Staff @dots{}
>>
@end example

Here is a small example:

@lilypond[verbatim,quote]
\relative c'' {
  \new PianoStaff <<
    \new Staff { \time 2/4 c4 e g g, }
    \new Staff { \clef bass c,, c' e c }
  >>
}
@end lilypond

Other staff groupings are introduced with @code{\new GrandStaff},
suitable for orchestral scores, and @w{@code{\new ChoirStaff}},
suitable for vocal scores.  These staff groups each form another
type of context, one that generates the brace at the left end of
every system and also controls the extent of bar lines.

Music Glossary: @rglos{chord}.

We saw earlier how notes can be combined into @notation{chords} by
indicating they are simultaneous by enclosing them in double angle
brackets.  However, the normal way of indicating a chord is to
surround the pitches with @emph{single} angle brackets.  Note that
all the notes in a chord must have the same duration, and that the
duration is placed after the closing bracket.

@lilypond[verbatim,quote,relative=2]

Think of chords as almost equivalent to single notes:
almost everything you can attach to a single note can be attached
to a chord, and everything must go @emph{outside} the angle
brackets.  For example, you can combine markings like beams and
ties with chords.  They must be placed outside the angle brackets.

The next line in the nursery rhyme is @notation{The moon doth

  }
  \addlyrics {
    Girls and boys come out to play,
    The moon doth shine as bright as day;
  }
>>
@end lilypond

We see the extra lyrics do not align properly with the notes.  The
word @notation{shine} should be sung on two notes, not one.  This
is called a @notation{melisma}, a single syllable sung to more
than one note.  There are several ways to spread a syllable over
multiple notes, the simplest being to add a slur across them, for
details, see @ref{Ties and slurs}:

@lilypond[verbatim,quote]
<<
  \relative c'' {
    \key g \major
    \time 6/8
    d4 b8 c4 a8 d4 b8 g4
    g8 a4 b8 c( b) a d4 b8 g4.
  }
  \addlyrics {
    Girls and boys come out to play,
    The moon doth shine as bright as day;
  }
>>
@end lilypond

The words now line up correctly with the notes, but the automatic
beaming for the notes above @notation{shine as} does not look right.
We can correct this by inserting manual beaming commands to override
the automatic beaming here, for details, see @ref{Automatic and
manual beams}.

@lilypond[verbatim,quote]
<<
  \relative c'' {
    \key g \major
    \time 6/8
    d4 b8 c4 a8 d4 b8 g4
    g8 a4 b8 c([ b]) a d4 b8 g4.
  }
  \addlyrics {
    Girls and boys come out to play,
    The moon doth shine as bright as day;
  }
>>
@end lilypond

As an alternative to using slurs, the melismata may be indicated
in just the lyrics by using an underscore @code{_} for each note
that should be included in the melisma:

@lilypond[verbatim,quote]

If a syllable extends over several notes or a single very long
note an @notation{extender line} is usually drawn from the
syllable extending under all the notes for that syllable.  It is
entered as two underscores @code{__}.  Here is an example from the
first three bars of @notation{Dido's Lament}, from Purcell's
@notation{Dido and Æneas}:

@lilypond[verbatim,quote]
<<
  \relative c'' {
    \key g \minor
    \time 3/2
    g2 a bes bes( a)
    b c4.( bes8 a4. g8 fis4.) g8 fis1
  }
  \addlyrics {
    When I am laid,
    am laid __ in earth,
  }
>>
@end lilypond

None of the examples so far have involved words containing more
than one syllable.  Such words are usually split one syllable to a
note, with hyphens between syllables.  Such hyphens are entered as
two dashes, resulting in a centered hyphen between the syllables.
Here is an example showing this and everything we have learned so
far about aligning lyrics to notes.

@c no ragged-right here because otherwise the hyphens get lost,
@c but the example is long enough to avoid looking strange.
@lilypond[verbatim,quote,noragged-right]
<<
  \relative c' {
    \key g \major
    \time 3/4
    \partial 4
    d4 g4 g a8( b) g4 g4
    b8( c) d4 d e4 c2
  }
  \addlyrics {
    A -- way in a __ man -- ger,
    no __ crib for a bed, __
  }

@end lilypond

Some lyrics, especially those in Italian, require the opposite:
setting more than one syllable to a single note.  This is
achieved by linking the syllables together with a single
underscore @code{_} (with no spaces), or enclosing them in quotes.
Here's an example from Rossini's @notation{Figaro}, where
@notation{al} has to be sung on the same note as the @notation{go} of
@notation{Largo} in Figaro's aria @notation{Largo al factotum}:

@c no ragged-right here because otherwise the hyphens get lost,
@c but the example is long enough to avoid looking strange.

The simple approach using @code{\addlyrics} can be used for
placing lyrics under more than one staff.  Here is an
example from Handel's @notation{Judas Maccabæus}:

@lilypond[verbatim,quote]
<<
  \relative c'' {
    \key f \major
    \time 6/8
    \partial 8
    c8 c([ bes]) a a([ g]) f f'4. b, c4.~ c4
  }
  \addlyrics {
    Let flee -- cy flocks the hills a -- dorn, __
  }
  \relative c' {
    \key f \major
    \time 6/8
    \partial 8
    r8 r4. r4 c8 a'([ g]) f f([ e]) d e([ d]) c bes'4
  }
  \addlyrics {
    Let flee -- cy flocks the hills a -- dorn,
  }

@end lilypond

Scores any more complex than this simple example are better
produced by separating out the score structure from the notes and
lyrics with variables.  These are discussed in @ref{Organizing
pieces with variables}.

This is the final section of the tutorial; it demonstrates how to
add the final touches to simple pieces, and provides an
introduction to the rest of the manual.

@node Organizing pieces with variables
@subsection Organizing pieces with variables

@cindex macros
@cindex assigning variables
@cindex using variables
@cindex variables, using
@cindex variables, characters allowed in
@cindex characters allowed in variables

When all of the elements discussed earlier are combined to produce
larger files, the music expressions get a lot bigger.  In
polyphonic music with many staves, the input files can become very
confusing.  We can reduce this confusion by using
@emph{variables}.

With variables (also known as identifiers or macros), we can break
up complex music expressions.  A variable is assigned as
follows:

@example
namedMusic = @{ @dots{} @}
@end example

The contents of the music expression @code{namedMusic} can be used
later by placing a backslash in front of the name
(@code{\namedMusic}, just like a normal LilyPond command).

@lilypond[verbatim,quote]
violin = \new Staff {
  \relative c'' {
    a4 b c b
  }
}
cello = \new Staff {
  \relative c {
    \clef bass
    e2 d
  }
}
{
  <<
    \violin
    \cello
  >>
}
@end lilypond

@noindent
The name of a variable must have alphabetic characters only, no
numbers, underscores, or dashes.

Variables must be defined @emph{before} the main music
expression, but may be used as many times as required anywhere after
they have been defined.  They may even be used in a later definition
of another variable, giving a way of shortening the input if a
section of music is repeated many times.

@lilypond[verbatim,quote]
tripletA = \times 2/3 { c,8 e g }
barA = { \tripletA \tripletA \tripletA \tripletA }

\relative c'' {
 \barA \barA
}
@end lilypond

Variables may be used for many other types of objects in
the input.  For example,

@example
width = 4.5\cm
name = "Wendy"
aFivePaper = \paper @{ paperheight = 21.0 \cm @}
@end example

Depending on its contents, the variable can be used in different
places.  The following example uses the above variables:

@example
\paper @{
  \aFivePaper
  line-width = \width
@}
@{
  c4^\name
@}
@end example


@node Version number
@subsection Version number

@cindex versioning
@cindex version
@cindex version number
@cindex upgrades
@cindex future upgrades
@cindex updating files
@cindex files, updating

@funindex \version
@funindex version
@funindex convert-ly

The @code{\version} statement records the version of LilyPond that
was used to write the file:

@example
\version @w{"@version{}"}
@end example

@noindent
By convention, this is placed at the top of your LilyPond file.

These annotations make future upgrades of LilyPond go more
smoothly.  Changes in the syntax are handled with a special
program, @command{convert-ly}, and it uses @code{\version} to
determine what rules to apply.  For details, see
@rprogram{Updating files with convert-ly}.


@node Adding titles
@subsection Adding titles

@cindex title
@cindex headers
@cindex header block

@funindex \header
@funindex header

The title, composer, opus number, and similar information are
entered in the @code{\header} block.  This exists outside of the
main music expression; the @code{\header} block is usually placed
underneath the version number.

@example
\version @w{"@version{}"}
\header @{
  title = "Symphony"
  composer = "Me"
  opus = "Op. 9"
@}

@{
  @dots{} music @dots{}
@}
@end example

When the file is processed, the title and composer are printed
above the music.  More information on titling can be found in
@ruser{Creating titles}.


@node Absolute note names
@subsection Absolute note names

@cindex note names
@cindex note names, absolute
@cindex absolute mode
@cindex absolute values for pitches
@cindex pitches, absolute values
@cindex absolute note names

So far we have always used @code{\relative} to define pitches.
This is the easiest way to enter most music, but another way of
defining pitches exists: absolute mode.

If you omit the @code{\relative}, LilyPond treats all pitches as
absolute values.  A @code{c'} will always mean middle C, a
@code{b} will always mean the note one step below middle C, and a
@code{g,} will always mean the note on the bottom staff of the
bass clef.

@lilypond[verbatim,quote]
{
  \clef bass
  c' b g, g,
  g, f, f c'
}
@end lilypond

Here is a four-octave scale:

@lilypond[verbatim,quote]
{
  \clef bass
  c, d, e, f,
  g, a, b, c
  d e f g
  a b c' d'
  \clef treble
  e' f' g' a'
  b' c'' d'' e''
  f'' g'' a'' b''
  c'''1
}
@end lilypond

As you can see, writing a melody in the treble clef involves a lot
of quote @code{'} marks.  Consider this fragment from Mozart:

@lilypond[verbatim,quote]
{
  \key a \major
  \time 6/8
  cis''8. d''16 cis''8 e''4 e''8
  b'8. cis''16 b'8 d''4 d''8
}
@end lilypond

All these quotes makes the input less readable and they are a source
of errors.  With @code{\relative}, the previous example is much
easier to read and type:

@lilypond[verbatim,quote]
\relative c'' {
  \key a \major
  \time 6/8
  cis8. d16 cis8 e4 e8
  b8. cis16 b8 d4 d8
}
@end lilypond

If you make a mistake with an octave mark (@code{'} or @code{,})
while working in @code{\relative} mode, it is very obvious -- many
notes will be in the wrong octave.  When working in absolute mode,
a single mistake will not be as visible, and will not be as easy
to find.

However, absolute mode is useful for music which has large
intervals, and is extremely useful for computer-generated LilyPond
files.



@node After the tutorial
@subsection After the tutorial

After finishing the tutorial, you should probably try writing a
piece or two.  Start by adding notes to one of the
@ref{Templates}.  If you need any notation that was not covered in
the tutorial, look at the Notation Reference, starting with
@ruser{Musical notation}.  If you want to write for an instrument
ensemble that is not covered in the templates, take a look at
@ref{Extending the templates}.

Once you have written a few short pieces, read the rest of the
Learning Manual (chapters 3-5).  There's nothing wrong with
reading it now, of course!  However, the rest of the Learning
Manual assumes that you are familiar with LilyPond input.  You may
wish to skim these chapters right now, and come back to them after
you have more experience.

In this tutorial and in the rest of the Learning Manual, there is a
paragraph @strong{See also} at the end of each section, which contains
cross-references to other sections: you should not follow these
cross-references at first reading; when you have read all of the
Learning Manual, you may want to read some sections again and follow
cross-references for further reading.

If you have not done so already, @emph{please} read
FIXME FIXME FIXME 
@c @ref{About the documentation}.
There is a lot of information about LilyPond, so
newcomers often do not know where they should look for help.  If
you spend five minutes reading that section carefully, you might
save yourself hours of frustration looking in the wrong places!
