-Tuplets are made from a music expression by multiplying all the

+Tuplets are made from a music expression with the @code{\tuplet}
+command, multiplying the speed of the music expression by a fraction:
@example
-\times @var{fraction} @{ @var{music} @}
+\tuplet @var{fraction} @{ @var{music} @}
@end example
@noindent
-The duration of @code{@var{music}} will be multiplied by the
-fraction. The fraction's denominator will be printed over or
-under the notes, optionally with a bracket. The most common
-tuplet is the triplet in which 3 notes have the duration of 2, so
-the notes are 2/3 of their written length.
+The fraction's numerator will be printed over or under the notes,

@node Ties
@unnumberedsubsubsec Ties
musical phrasing. A tie is just a way of extending a note
duration, similar to the augmentation dot.}
-A tie is entered using the tilde symbol (@code{~}).
+A tie is entered by appending a tilde symbol (@code{~}) to the first
+of each pair of notes being tied. This indicates that the note
+should be tied to the following note, which must be at the same pitch.
+
+@lilypond[quote,verbatim]
+{ a'2~ 4~ 16 r r8 }
+@end lilypond
+
+Ties can make use of the @q{last explicit pitch} interpretation of
+isolated durations:
-@lilypond[quote,verbatim,relative=2]
-a2 ~ a
+@lilypond[quote,verbatim]

@end lilypond
Ties are used either when the note crosses a bar line, or when
used when note values cross larger subdivisions of the measure:
@lilypond[verbatim,quote]
-\relative c' {
- r8 c8 ~ c2 r4 |
- r8^"not" c2 ~ c8 r4
+\relative {
+ r8 c'~ 2 r4 |
+ r8^"not" c2~ 8 r4
}
@end lilypond
When a tie is applied to a chord, all note heads whose pitches
match are connected. When no note heads match, no ties will be
-created. Chords may be partially tied by placing the tie inside
+created. Chords may be partially tied by placing the ties inside
the chord.

A basic metronome mark is simple to write:
-@lilypond[verbatim,quote,relative=1]
-\tempo 4 = 120
-c2 d
-e4. d8 c2
+@lilypond[verbatim,quote]
+\relative {
+ \tempo 4 = 120
+ c'2 d
+ e4. d8 c2
+}
@end lilypond
Metronome marks may also be printed as a range of two numbers:
-@lilypond[verbatim,quote,relative=1]
-\tempo 4 = 40 ~ 46
-c4. e8 a4 g
-b,2 d4 r
+@lilypond[verbatim,quote]
+\relative {
+ \tempo 4 = 40 - 46
+ c'4. e8 a4 g
+ b,2 d4 r
+}
@end lilypond
Tempo indications with text can be used instead:
-@lilypond[verbatim,quote,relative=2]
-\tempo "Allegretto"
-c4 e d c
-b4. a16 b c4 r4
+@lilypond[verbatim,quote]
+\relative {
+ \tempo "Allegretto"
+ c''4 e d c
+ b4. a16 b c4 r4
+}
@end lilypond
Combining a metronome mark and text will automatically place the
metronome mark within parentheses:
-@lilypond[verbatim,quote,relative=2]
-\tempo "Allegro" 4 = 160
-g4 c d e
-d4 b g2
+@lilypond[verbatim,quote]
+\relative {
+ \tempo "Allegro" 4 = 160
+ g'4 c d e
+ d4 b g2
+}
@end lilypond
In general, the text can be any markup object:
-@lilypond[verbatim,quote,relative=2]
-\tempo \markup { \italic Faster } 4 = 132
-a8-. r8 b-. r gis-. r a-. r
+@lilypond[verbatim,quote]
+\relative {
+ \tempo \markup { \italic Faster } 4 = 132
+ a'8-. r8 b-. r gis-. r a-. r
+}
@end lilypond
A parenthesized metronome mark with no textual indication may be
written by including an empty string in the input:
-@lilypond[verbatim,quote,relative=2]
-\tempo "" 8 = 96
-d4 g e c
+@lilypond[verbatim,quote]
+\relative {
+ \tempo "" 8 = 96
+ d''4 g e c
+}
@end lilypond

+
+In a part for an instrument with long periods of rests,
+tempo indications sometimes follow each other closely.
+The command @code{\markLengthOn} provides extra horizontal space
+to prevent tempo indications from overlapping, and @code{\markLengthOff}
+restores the default behavior of ignoring tempo marks
+for horizontal spacing.

+
+The @code{"="} bar line provides the double span bar line, used
+in combination with the segno sign. Do not use it as a standalone
+double thin bar line; here, @code{\bar} @var{"||"} is
+preferred.
+
+The @code{"-"} sign starts annotations to bar lines which
+are useful to distinguish those with identical appearance
+but different behavior at line breaks and/or different span bars.
+The part following the @code{"-"} sign is not used for building up
+the bar line.

Grace notes are musical ornaments, printed in a smaller font, that take
up no additional logical time in a measure.

There are three other types of grace notes possible; the
between notes that are slurred themselves, using the
@code{\slashedGrace} function.
-@lilypond[quote,relative=2,verbatim]
-\acciaccatura d8 c4
-\appoggiatura e8 d4
-\acciaccatura { g16[ f] } e2
-\slashedGrace a,8 g4
-\slashedGrace b16 a4(
-\slashedGrace b8 a2)
+@lilypond[quote,verbatim]
+\relative {
+ \acciaccatura d''8 c4
+ \appoggiatura e8 d4

The placement of grace notes is synchronized between different staves.
In the following example, there are two sixteenth grace notes for every
eighth grace note
-@lilypond[quote,relative=2,verbatim]
+@lilypond[quote,verbatim]
<<
- \new Staff { e2 \grace { c16[ d e f] } e2 }
- \new Staff { c2 \grace { g8[ b] } c2 }
+ \new Staff \relative { e''2 \grace { c16 d e f } e2 }
+ \new Staff \relative { c''2 \grace { g8 b } c2 }

@end lilypond
command. It takes two arguments: the main note, and the grace
notes following the main note.
-@lilypond[quote,verbatim,relative=2]
-c1 \afterGrace d1 { c16[ d] } c1
+@lilypond[quote,verbatim]
+\relative { c''1 \afterGrace d1 { c16[ d] } c1 }
@end lilypond
This will put the grace notes after a space lasting 3/4 of the
the results from setting the space at the default, at 15/16, and
finally at 1/2 of the main note.
-@lilypond[quote,verbatim,relative=2]
+@lilypond[quote,verbatim]
<<
- \new Staff {
- c1 \afterGrace d1 { c16[ d] } c1
+ \new Staff \relative {
+ c''1 \afterGrace d1 { c16[ d] } c1
}
- \new Staff {
+ \new Staff \relative {
#(define afterGraceFraction (cons 15 16))
- c1 \afterGrace d1 { c16[ d] } c1
+ c''1 \afterGrace d1 { c16[ d] } c1
}
- \new Staff {

specified using spacers. The following example places the grace
note after a space lasting 7/8 of the main note.
-@lilypond[quote,verbatim,relative=2]
-\new Voice {

+\new Voice \relative {
<<

direction is overridden and then reverted.

synchronized. Take care when you mix staves with grace notes and
staves without, for example,
-@lilypond[quote,relative=2,verbatim]
+@lilypond[quote,verbatim]
<<
- \new Staff { e4 \bar "|:" \grace c16 d2. }
- \new Staff { c4 \bar "|:" d2. }
+ \new Staff \relative { e''4 \bar ".|:" \grace c16 d2. }
+ \new Staff \relative { c''4 \bar ".|:" d2. }

@end lilypond
This can be remedied by inserting grace skips of the corresponding
durations in the other staves. For the above example
-@lilypond[quote,relative=2,verbatim]
+@lilypond[quote,verbatim]
<<
- \new Staff { e4 \bar "|:" \grace c16 d2. }
- \new Staff { c4 \bar "|:" \grace s16 d2. }
+ \new Staff \relative { e''4 \bar ".|:" \grace c16 d2. }
+ \new Staff \relative { c''4 \bar ".|:" \grace s16 d2. }

@end lilypond
-The use of grace notes within voice contexts confuses the way the voice
-is typeset. This can be overcome by inserting a rest or note between the
-voice command and the grace note.

- \acciaccatura { f8 } e8 r8 \acciaccatura { f8 } e8 r4

- \relative c'' {

+Please make sure that you use the @code{\grace} command for the
+spacer part, even if the visual part uses @code{\acciaccatura} or
+@code{\appoggiatura} because otherwise an ugly slur fragment will
+be printed, connecting the invisible grace note with the following
+note.
Grace sections should only be used within sequential music expressions.
Nesting or juxtaposing grace sections is not supported, and might
duration, for example:
@example
-\acciaccatura @{ c'8[ d' e' f' g'] @}
+c'8 \acciaccatura @{ c'8[ d' e' f' g'] @}
@end example
becomes:
@example
-\acciaccatura @{ c'16[ d' e' f' g'] @}
+c'8 \acciaccatura @{ c'16[ d' e' f' g'] @}
@end example
Or explicitly change the musical duration:
@example
-\acciaccatura @{ \scaleDurations 1/2 @{ c'8[ d' e' f' g'] @} @}
+c'8 \acciaccatura @{ \scaleDurations 1/2 @{ c'8[ d' e' f' g'] @} @}
@end example
See @ref{Scaling durations}.

+MyCadenza = \relative {

The next bar line then falls at 9/8 rather than 5/4.
