+@node Compiling a file
+@subsection Compiling a file
+
+The first example demonstrates how to start working with LilyPond.  To
+create sheet music, we write a text file that specifies the
+notation.  For example, if we write
 
 @example
 @{
-c d e f g a b
+  c' e' g' e'
 @}
 @end example
 
 @noindent
 the result looks like this
 
-@lilypond[fragment,quote,notime,relative=1]
-c d e f g a b
+@c  in this case we don't want verbatim
+@lilypond[quote,ragged-right]
+{
+  c' e' g' e'
+}
 @end lilypond
 
-Every piece of LilyPond input needs to have @{curly braces@} placed
-around the input.  For the rest of this manual, most examples will
-omit these braces, but don't forget them in your own music!
-
-In addition, many examples use @code{relative} mode.  This is explained
-in @ref{Octave entry}; for now simply be aware that some examples
-should be placed inside @code{\relative @{ @emph{...music...} @}}
+@strong{Warning:} Every piece of LilyPond input needs to have @strong{@{ curly
+braces @}} placed around the input.  The braces should also be
+surrounded by a space unless they are at the beginning or end of a
+line to avoid ambiguities.  These may be omitted in some examples in this
+manual, but don't forget them in your own music!
 
 @cindex Case sensitive
-Finally, LilyPond input is case sensitive.  @code{ @{ c d e @} } is
-valid input; @code{ @{ C D E @} } will produce an error message.
-
-The @rglos{duration} of a note is specified by a number after the note
-name.  @samp{1} for a @rglos{whole note}, @samp{2} for a @rglos{half note},
-@samp{4} for a @rglos{quarter note} and so on
-

-@lilypond[fragment,quote,notime,relative=2]
-\set Staff.autoBeaming = ##f
-{ a1 a2 a4 a16 a32 s16_" " }

-
-If you do not specify a duration, the duration last entered is used
-for the next notes.  The duration of the first note in input defaults
-to a quarter

-Key signatures together with the pitches (including alterations) are
-used to determine when to print accidentals.  This is a
-feature that often causes confusion to newcomers, so let us explain it
-in more detail.
+This behavior may be altered, but in most cases these automatic values
+are useful.
 
 
-LilyPond makes a sharp distinction between musical content and
-layout.  The alteration (flat, natural or sharp) of a note is part of
-the pitch, and is therefore musical content.  Whether an accidental (a
-flat, natural or sharp @emph{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.
+@subheading Pitches
 
-In this example
+The easiest way to enter notes is by using @code{\relative} mode.  In
+this mode, the @rglos{interval} between the previous note and the
+current note is assumed to be within a @rglos{fourth}.  We begin by
+entering the most elementary piece of music, a @rglos{scale}.
 
-@lilypond[quote,notime,fragment]
-\key d \major
-d' cis' fis'
+@lilypond[quote,ragged-right,verbatim]
+\relative c' {
+  c d e f
+  g a b c
+}
 @end lilypond
 
-@noindent
-no note has an explicit accidental, but you still must enter
+The initial note is @rglos{middle C}.  Each successive note
+is within a fourth of the previous note -- in other words, the first
+@samp{c} is the closest C to middle C.  This is followed by the closest
+D to the previous note.  We can create melodies which have larger intervals:
 
-@example
-\key d \major
-d cis fis
-@end example
+@lilypond[quote,ragged-right,verbatim]
+\relative c' {
+  d f a g
+  c b f d
+}
+@end lilypond
 
 @noindent
-The code @samp{d} does not mean `print a black dot just below the
-staff.'  Rather, it means: `a note with pitch D-natural.'  In the key
-of A-flat major, it does get an accidental
+As you may notice, this example does not start on middle C.  The first
+note -- the @samp{d} -- is the closest D to middle C.
 
-@lilypond[quote,notime,fragment,relative=1,verbatim]
-\key as \major
-d
+To add intervals that are larger than a fourth, we can raise the octave
+by adding a single quote @code{'} (or apostrophe) to the note name.  We can
+lower the octave by adding a comma @code{,} to the note name.
+
+@lilypond[quote,ragged-right,verbatim]
+\relative c'' {
+  a a, c' f,
+  g g'' a,, f'
+}
 @end lilypond
 
-Adding all alterations explicitly might require a little more effort
-when typing, but the advantage is that transposing is easier, and
-accidentals can be printed according to different conventions.  See
-@ref{Automatic accidentals}, for some examples how accidentals can be printed
-according to different rules.
+@noindent
+To change a note by two (or more!) octaves, we use multiple @code{''} or
+@code{,,} -- but be careful that you use two single quotes @code{''} and
+not one double quote @code{"}@tie{}!  The initial value in
+@code{\relative c'} may also be modified like this.

-previous one.  For example, @samp{c f} goes up while @samp{c g} goes
-down.
+@item @strong{Expressions:}
+Every piece of LilyPond input needs to have
+@strong{@{ curly braces @}} placed around the input.  These braces tell
+LilyPond that the input is a single music expression, just like
+parenthesis @samp{()} in mathematics.  The braces should
+be surrounded by a space unless they are at the beginning or end of a
+line to avoid ambiguities.
 
-To use relative mode, add @code{\relative} before the piece of
-music.  The first note is taken relative to the middle C
-@c no , for this sentence
-(i.e., @code{c'})
+A function (such as @code{\relative @{ @}} ) also counts as a single

+@item @strong{Comments}:
+A comment is a remark for the human reader of the music input; it is

+There are two types of comments.  The percent symbol @samp{%}
+introduces a line comment; anything after @samp{%} on that line is
+ignored.  A block comment marks a whole section of music
+input as a comment.  Anything that is enclosed in @code{%@{} and @code{%@}} is
+ignored.  The following fragment shows possible uses for comments

-This technique is useful for non-monophonic music.  To enter music

-@code{>>}.  In the following example, three sequences (all containing
-two separate notes) are combined simultaneously
+LilyPond examines pitches based on the note names -- in other words,
+an augmented fourth is @emph{not} the same as a diminished fifth.  If we
+begin at a C, then an F-sharp will be placed a higher than the C, while
+a G-flat will be placed lower than the C.

+A @rglos{sharp} pitch is made by adding @samp{is} to

-Music files with deep nesting can be confusing to enter and
-maintain.  One convention that helps against this confusion is
-indenting.  When entering a file with deep nesting of braces and
-angles, it is customary to use an indent that indicates the nesting
-level.  Formatting music like this eases reading and helps you insert
-the right number of closing braces at the end of an expression.  For
-example,
+@sp 1
 
-@example
-<<
-  @{
-    @dots{}
-  @}
-  @{
-    @dots{}
-  @}
->>
-@end example
+@subheading Warning: key signatures and pitches
 
-Some editors have special support for entering LilyPond, and can help
-indenting source files.  See @ref{Editor support} for more information.
+To determine whether to print an accidental, LilyPond examines the
+pitches and the key signature.  The key signature only effects
+the @emph{printed} accidentals, not the actual pitches!  This is a
+feature that often causes confusion to newcomers, so let us explain it
+in more detail.
 
-@node More staves
-@section More staves
+LilyPond makes a sharp distinction between musical content and
+layout.  The alteration (flat, natural or 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.
 
-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{>>}, as demonstrated here
+In this example
 
-@lilypond[quote,fragment,verbatim]
-<<
-  \new Staff { \clef treble c'' }
-  \new Staff { \clef bass c }
->>
+@lilypond[quote,ragged-right,verbatim,fragment,relative=2]
+\key d \major
+d cis fis
 @end lilypond
 
+@noindent
+No note has a printed accidental, but you must still add the @samp{is} to
+@code{cis} and @code{fis}.
 
-The command @code{\new} introduces a `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.  This ensures that each fragment
-gets its own stave.
+The code @samp{e} does not mean @qq{print a black dot just below the
+first line of the staff.}  Rather, it means: @qq{there is a note with
+pitch E-natural.}  In the key of A-flat major, it @emph{does} get an
+accidental:
 
-There are several types of contexts.  @code{Staff}, @code{Voice} and
-@code{Score} handle melodic notation, while @code{Lyrics} sets lyric
-texts and @code{ChordNames} prints chord names.
+@lilypond[quote,ragged-right,verbatim,fragment,relative=2]
+\key aes \major
+e
+@end lilypond
 
-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.
+Adding all alterations explicitly might require a little more effort
+when typing, but the advantage is that transposing is easier, and
+accidentals can be printed according to different conventions.  See
+@ref{Automatic accidentals} for some examples how accidentals can be printed
+according to different rules.

+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 @samp{+},
+@samp{*} and @samp{/}) and parentheses.  Like mathematical expressions,
+music expressions can be nested arbitrarily deep, which is necessary
+for complex music like polyphonic scores.
+
+
+@node Multiple staves
+@subsection Multiple staves
+
+As we saw in @ref{Music expressions explained}, LilyPond input files
+are constructed out of music expressions.  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[quote,ragged-right,verbatim]
+\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.
 
-@node Advanced rhythmic commands
-@section Advanced rhythmic commands
+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.
 
-@cindex pickup
-@cindex anacruse
-@cindex partial measure
-A pickup is entered with the keyword @code{\partial}.  It
-is followed by a duration: @code{\partial 4} is a quarter note upstep
-and @code{\partial 8} an eighth note
+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.

-In ensemble pieces, one of the voices often does not play for many
-measures.  This is denoted by a special rest, the multi-measure
-rest.  It is entered with a capital @samp{R} followed by a duration
-(1@tie{}for a whole note, 2@tie{}for a half note, etc.).  By multiplying the
-duration, longer rests can be constructed.  For example, this rest
-takes 3@tie{}measures in 2/4 time
-
-@example
-R2*3
-@end example
-
-When printing the part, multi-rests
-must be condensed.  This is done by setting a run-time variable
-
-@example
-\set Score.skipBars = ##t
-@end example
-
-@noindent
-This command sets the property @code{skipBars} in the
-@code{Score} context to true (@code{##t}).  Prepending the rest and
-this option to the music above, leads to the following result
-
-@lilypond[quote,ragged-right]
-\transpose f c' \relative c {
-  \time 2/4
-  \set Score.skipBars = ##t 
-  R2*3
-  r4 f8 a cis4 f e d

-@end lilypond

-
-The score is made by combining all of the music together.  Assuming
-that the other voice is in @code{bassoonNotes} in the file
-@file{bassoon-music.ly}, a score is made with
-
-@example
-\include "bassoon-music.ly"
-\include "horn-music.ly"
-
-<<
-  \new Staff \hornNotes
-  \new Staff \bassoonNotes

+@node After the tutorial
+@subsection After the tutorial
 
-Setting run-time variables (`properties') is discussed in
-@ref{Changing context properties on the fly}.
+After finishing the tutorial, you should probably try writing a
+piece or two.  Start with one of the @ref{Templates} and
+add notes.  If you need any notation that was not covered in the
+tutorial, look at the Notation Reference, starting with
+@ref{Basic notation}.  If you want to write for an instrument
+ensemble which 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 them 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.

-* discuss expectations (?)
+As we saw in @ref{How to read the tutorial}, many examples in the
+tutorial omitted a @code{\relative c'' @{ ... @}} around the printed
+example.
 
-* conclude tutorial
+In the rest of the manual, we are much more lax about the
+printed examples: sometimes they may have omitted a
+@code{\relative c'' @{ ... @}}, but in other times a different initial
+pitch may be used (such as @code{c'} or @code{c,,}), and in some cases
+the whole example is in absolute note mode!  However, ambiguities like
+this only exist where the pitches are not important.  In any example
+where the pitch matters, we have explicitly stated our @code{\relative}
+our our absolute-mode @code{@{ @}}.
 
-* overview of chapters?
+If you are still confused about the exact LilyPond input that was
+used in an example, read the HTML version (if you are not already doing
+so) and click on the picture of the music.  This will display the exact
+input that LilyPond used to generate this manual.
