This chapter explains how to create musical notation.
This section discusses how to specify the pitch of notes. There are three steps to this process: input, modification, and output.
This section discusses how to input pitches. There are two different ways to place notes in octaves: absolute and relative mode. In most cases, relative mode will be more convenient.
A pitch name is specified using lowercase letters a
through g. The note names c to b are
engraved in the octave below middle C.
\clef bass
c d e f
g a b c
d e f g
Other octaves may be specified with a single quote (')
or comma (,) character. Each ' raises the
pitch by one octave; each , lowers the pitch by an
octave.
\clef treble
c' c'' e' g
d'' d' d c
\clef bass
c, c,, e, g
d,, d, d c
Music Glossary: Pitch names.
Snippets: Pitches.
When octaves are specified in absolute mode it is easy to accidentally put a pitch in the wrong octave. Relative octave mode reduces these errors since most of the time it is not necessary to indicate any octaves at all. Furthermore, in absolute mode a single mistake may be difficult to spot, while in relative mode a single error puts the rest of the piece off by one octave.
\relative startpitch musicexpr
In relative mode, each note is assumed to be as close to the previous note as possible. This means that the octave of each pitch inside musicexpr is calculated as follows:
' or , can be
added to respectively raise or lower a pitch by an extra octave,
relative to the pitch calculated without an octave mark.
'' and ,, will alter the pitch by two
octaves.
c.
Here is the relative mode shown in action:
\relative c {
\clef bass
c d e f
g a b c
d e f g
}
Octave changing marks are used for intervals greater than a fourth:
\relative c'' {
c g c f,
c' a, e'' c
}
A note sequence without a single octave mark can nevertheless span large intervals:
\relative c {
c f b e
a d g c
}
If the preceding item is a chord, the first note of the chord is
used as the reference point for the octave placement of a
following note or chord. Inside chords, the next note is always
relative to the preceding one. Examine the next example
carefully, paying attention to the c notes.
\relative c' {
c
<c e g>
<c' e g'>
<c, e, g''>
}
As explained above, the octave of pitches is calculated only with the note names, regardless of any alterations. Therefore, an E-double-sharp following a B will be placed higher, while an F-double-flat will be placed lower. In other words, a double-augmented fourth is considered a smaller interval than a double-diminished fifth, regardless of the number of semitones that each interval contains.
\relative c'' {
c2 fis
c2 ges
b2 eisis
b2 feses
}

Internals Reference: RelativeOctaveMusic.
The relative conversion will not affect \transpose,
\chordmode or \relative sections in its argument.
To use relative mode within transposed music, an additional
\relative must be placed inside \transpose.
If no startpitch is specified for \relative,
then c' is assumed. However, this is a deprecated
option and may disappear in future versions, so its use is
discouraged.
Note: New users are sometimes confused about accidentals and
key signatures. In LilyPond, note names are the raw input; key
signatures and clefs determine how this raw input is displayed.
An unaltered note like c means ‘C natural’,
regardless of the key signature or clef. For more information,
see Accidentals and key signatures.
|
A sharp pitch is made by adding is to the note
name, and a flat pitch by adding es. As you
might expect, a double sharp or double flat
is made by adding isis or eses. This syntax is
derived from Dutch note naming conventions. To use other names
for accidentals, see Note names in other languages.
ais1 aes aisis aeses
A natural will cancel the effect of an accidental or key signature. However, naturals are not encoded into the note name syntax with a suffix; a natural pitch is shown as a simple note name:
a4 aes a2
Quarter tones may be added; the following is a series of Cs with increasing pitches:
ceseh1 ces ceh c cih cis cisih
Normally accidentals are printed automatically, but you may also
print them manually. A reminder accidental can be forced by
adding an exclamation mark ! after the pitch. A
cautionary accidental (i.e., an accidental within parentheses) can
be obtained by adding the question mark ? after the
pitch. These extra accidentals can also be used to produce
natural signs.
cis cis cis! cis? c c c! c?
Accidentals on tied notes are only printed at the beginning of a new system:
cis1 ~ cis ~
\break
cis
Preventing extra naturals from being automatically added
In accordance with standard typesetting rules, a natural sign is
printed before a sharp or flat if a previous accidental on the same
note needs to be canceled. To change this behavior, set the
extraNatural property to "false" in the Staff context.
\relative c'' {
aeses4 aes ais a
\set Staff.extraNatural = ##f
aeses4 aes ais a

There are no generally accepted standards for denoting quarter-tone accidentals, so LilyPond's symbol does not conform to any standard.
There are predefined sets of note names for various other
languages. To use them, include the language-specific init file.
For example, to use English notes names, add
\include "english.ly" to the top of the input file.
The available language files and the note names they define are:
| Language | Note names | sharp | flat | double sharp | double flat
|

In Dutch, aes is contracted to as, but both forms
are accepted in LilyPond. Similarly, both es and
ees are accepted. This also applies to
aeses / ases and
eeses / eses. Sometimes only these
contracted names are defined in the corresponding language files.
a2 as e es a ases e eses
Some music uses microtones whose alterations are fractions of a ‘normal’ sharp or flat. The note names for quarter-tones defined in the various language files are listed in the following table. Here the prefixes semi- and sesqui- mean ‘half’ and ‘one and a half’, respectively. For the other languages, no special names have been defined yet.

This section discusses how to modify pitches.
In relative mode, it is easy to forget an octave changing mark. Octave checks make such errors easier to find by displaying a warning and correcting the octave if a note is found in an unexpected octave.
To check the octave of a note, specify the absolute octave after
the = symbol. This example will generate a warning
(and change the pitch) because the second note is the absolute
octave d'' instead of d' as indicated by the octave
correction.
\relative c'' {
c2 d='4 d
e2 f
}
The octave of notes may also be checked with the
\octaveCheck controlpitch command.
controlpitch is specified in absolute mode. This checks
that the interval between the previous note and the
controlpitch is within a fourth (i.e., the normal
calculation of relative mode). If this check fails, a warning is
printed, but the previous note is not changed. Future notes are
relative to the controlpitch.
\relative c'' {
c2 d
\octaveCheck c'
e2 f
}
Compare the two bars below. The first and third \octaveCheck
checks fail, but the second one does not fail.
\relative c'' {
c4 f g f

A music expression can be transposed with \transpose. The
syntax is
\transpose frompitch topitch musicexpr
This means that musicexpr is transposed by the interval between the pitches frompitch and topitch: any note with pitch frompitch is changed to topitch and any other note is transposed by the same interval. Both pitches are entered in absolute mode.
Consider a piece written in the key of D-major. It can be transposed up to E-major; note that the key signature is automatically transposed as well.
\transpose d e {
\relative c' {
\key d \major
d4 fis a d
}
}
If a part written in C (normal concert pitch) is to be played on the A clarinet (for which an A is notated as a C and thus sounds a minor third lower than notated), the appropriate part will be produced with:
\transpose a c' {
\relative c' {
\key c \major
c4 d e g
}
}
Note that we specify \key c \major explicitly. If we
do not specify a key signature, the notes will be transposed but
no key signature will be printed.
\transpose distinguishes between enharmonic pitches: both
\transpose c cis or \transpose c des will
transpose up a semitone. The first version will print sharps and
the notes will remain on the same scale step, the second version
will print flats on the scale step above.
music = \relative c' { c d e f }
\new Staff {
\transpose c cis { \music }
\transpose c des { \music }
}
\transpose may also be used in a different way, to input
written notes for a transposing instrument. The previous examples
show how to enter pitches in C (or concert pitch) and
typeset them for a transposing instrument, but the opposite is
also possible if you for example have a set of instrumental parts
and want to print a conductor's score. For example, when entering
music for a B-flat trumpet that begins on a notated E (concert D),
one would write:
musicInBflat = { e4 ... }
\transpose c bes, \musicInBflat
To print this music in F (e.g., rearranging to a French horn) you
could wrap the existing music with another \transpose:
musicInBflat = { e4 ... }
\transpose f c' { \transpose c bes, \musicInBflat }
For more information about transposing instruments, see Instrument transpositions.
Transposing music with minimum accidentals
This example uses some Scheme code to enforce enharmonic modifications for notes in order to have the minimum number of accidentals. In this case, the following rules apply:
In this manner, the most natural enharmonic notes are chosen.
#(define (naturalize-pitch p)
(let* ((o (ly:pitch-octave p))

The relative conversion will not affect \transpose,
\chordmode or \relative sections in its argument.
To use relative mode within transposed music, an additional
\relative must be placed inside \transpose.
This section discusses how to alter the output of pitches.
The clef may be altered. Middle C is shown in every example.
\clef treble

\clef alto

\clef tenor

\clef bass

\break
\clef varbaritone

\clef subbass
c2 c
\clef percussion
c2 c
\clef tab
c2 c
Further supported clefs are described under Ancient clefs.
By adding _8 or ^8 to the clef name, the
clef is transposed one octave down or up, respectively,
and _15 and ^15 transpose by two octaves.
The clef name must be enclosed in quotes when it contains
underscores or digits.
\clef treble
c2 c
\clef "treble_8"
c2 c
\clef "bass^15"
c2 c
Tweaking clef properties
The command \clef "treble_8" is equivalent to setting
clefGlyph, clefPosition (which controls the vertical
position of the clef), middleCPosition and
clefOctavation. A clef is printed when any of the properties
except middleCPosition are changed.
Note that changing the glyph, the position of the clef, or the
octavation does not in itself change the position of subsequent notes
on the staff: the position of middle C must also be specified to do
this. The positional parameters are relative to the staff center line,
positive numbers displacing upwards, counting one for each line and
space. The clefOctavation value would normally be set to 7, -7,
15 or -15, but other values are valid.
When a clef change takes place at a line break the new clef symbol is
printed at both the end of the previous line and the beginning of the
new line by default. If the warning clef at the end of the previous
line is not required it can be suppressed by setting the Staff
property explicitClefVisibility to the value
end-of-line-invisible. The default behavior can be recovered
with \unset Staff.explicitClefVisibility.
The following examples show the possibilities when setting these properties manually. On the first line, the manual changes preserve the standard relative positioning of clefs and notes, whereas on the second line, they do not.

Note: New users are sometimes confused about accidentals and
key signatures. In LilyPond, note names are the raw input; key

An unaltered note like c means ‘C natural’,
regardless of the key signature or clef. For more information,
see Accidentals and key signatures.

The key signature indicates the tonality in which a piece is played. It is denoted by a set of alterations (flats or sharps) at the start of the staff. The key signature may be altered:
\key pitch mode
Here, mode should be \major or \minor to get a
key signature of pitch-major or pitch-minor,
respectively. You may also use the standard mode names, also
called church modes: \ionian, \dorian,
\phrygian, \lydian, \mixolydian,
\aeolian, and \locrian.
\key g \major
fis1
f
fis
Preventing natural signs from being printed when the key signature changes
When the key signature changes, natural signs are automatically printed
to cancel any accidentals from previous key signatures. This may be
prevented by setting to "false" the printKeyCancellation
property in the Staff context.
\relative c' {
\key d \major
a4 b cis d
\key g \minor
a4 bes c d
\set Staff.printKeyCancellation = ##f
\key d \major
a4 b cis d
\key g \minor
a4 bes c d
}
Non-traditional key signatures
The commonly used \key command sets the keySignature
property, in the Staff context.
To create non-standard key signatures, set this property directly. The format of this command is a list:
\set Staff.keySignature = #`(((octave . step) . alter) ((octave
. step) . alter) ...) where, for each element in the list,
octave specifies the octave (0 being the octave from middle C to
the B above), step specifies the note within the octave (0 means
C and 6 means B), and alter is ,SHARP ,FLAT ,DOUBLE-SHARP
etc. (Note the leading comma.)
Alternatively, for each item in the list, using the more concise format
(step . alter) specifies that the same alteration should hold in
all octaves.
Here is an example of a possible key signature for generating a whole-tone scale:
\relative c' {
\set Staff.keySignature = #`(((0 . 3) . ,SHARP) ((0 . 5) . ,FLAT) ((0 . 6) . ,FLAT))
c4 d e fis

Ottava brackets introduce an extra transposition of an octave for the staff:

The set-octavation function also takes -1 (for 8va bassa),
2 (for 15ma), and -2 (for 15ma bassa) as arguments.

Internally, the set-octavation function sets the properties
ottavation (for example, to "8va" or "8vb")
and middleCPosition. To override the text of the bracket, set
ottavation after invoking set-octavation.

When typesetting scores that involve transposing instruments, some parts can be typeset in a different pitch than the concert pitch. In these cases, the key of the transposing instrument should be specified; otherwise the MIDI output and cues in other parts will produce incorrect pitches. For more information about quotations, see Quoting other voices.
\transposition pitch
The pitch to use for \transposition should correspond to
the real sound heard when a c' written on the staff is
played by the transposing instrument. This pitch is entered in
absolute mode, so an instrument that produces a real sound which
is one tone higher than the printed music should use
\transposition d'. \transposition should
only be used if the pitches are not being entered in
concert pitch.
Here are a few notes for violin and B-flat clarinet where the parts have been entered using the notes and key as they appear in each part of the conductor's score. The two instruments are playing in unison.
\new GrandStaff <<
\new Staff = "violin" {
\relative c'' {
\set Staff.instrumentName = "Vln"
\set Staff.midiInstrument = "violin"

There are many different conventions on how to typeset accidentals. LilyPond provides a function to specify which accidental style to use. This function is called as follows:
\new Staff <<
#(set-accidental-style 'voice)
{ ... }
>>
The accidental style applies to the current Staff by
default (with the exception of the styles piano and
piano-cautionary, which are explained below). Optionally,
the function can take a second argument that determines in which
scope the style should be changed. For example, to use the same
style in all staves of the current StaffGroup, use:
#(set-accidental-style 'voice 'StaffGroup)
The following accidental styles are supported. To demonstrate each style, we use the following example:
musicA = {
<<
\relative c' {
cis'8 fis, d'4 <a cis>8 f bis4 |
cis2. <c, g'>4 |
}
\\
\relative c' {
ais'2 cis, |
fis8 b a4 cis2 |
}
>>
}
musicB = {
\clef bass
\new Voice {
\voiceTwo \relative c' {
<fis, a cis>4
\change Staff = up
cis'
\change Staff = down
<fis, a>
\change Staff = up
dis' |
\change Staff = down
<fis, a cis>4 gis <f a d>2 |
}
}
}
\new PianoStaff {
<<
\context Staff = "up" {
#(set-accidental-style 'default)
\musicA
}
\context Staff = "down" {
#(set-accidental-style 'default)
\musicB
}
>>
}
Note that the last lines of this example can be replaced by the following, as long as the same accidental style should be used in both staves.
\new PianoStaff {
<<
\context Staff = "up" {
%%% change the next line as desired:
#(set-accidental-style 'default 'Score)
\musicA
}
\context Staff = "down" {
\musicB
}
>>
}
defaultb in the second measure or the
last c:
voiceStaff-level. In this style, however, accidentals are
typeset individually for each voice. Apart from that, the rule is
similar to default.
As a result, accidentals from one voice do not get canceled in
other voices, which is often an unwanted result: in the following
example, it is hard to determine whether the second a
should be played natural or sharp. The voice option should
therefore be used only if the voices are to be read solely by
individual musicians. If the staff is to be used by one musician
(e.g., a conductor or in a piano score) then modern or
modern-cautionary should be used instead.
modernThis rule corresponds to the common practice in the twentieth
century. It prints the same accidentals as default, with
two exceptions that serve to avoid ambiguity: after temporary
accidentals, cancellation marks are printed also in the following
measure (for notes in the same octave) and, in the same measure,
for notes in other octaves. Hence the naturals before
the b and the c in the second measure of
the upper staff:
modern-cautionaryThis rule is similar to modern, but the ‘extra’
accidentals (the ones not typeset by default) are typeset
as cautionary accidentals. They are by default printed with
parentheses, but they can also be printed in reduced size by
defining the cautionary-style property of
AccidentalSuggestion.
modern-voiceThis rule is used for multivoice accidentals to be read both by
musicians playing one voice and musicians playing all voices.
Accidentals are typeset for each voice, but they are
canceled across voices in the same Staff. Hence,
the a in the last measure is canceled because the
previous cancellation was in a different voice, and
the d in the lower staff is canceled because of the
accidental in a different voice in the previous measure:
modern-voice-cautionarymodern-voice, but with the extra
accidentals (the ones not typeset by voice) typeset as
cautionaries. Even though all accidentals typeset by
default are typeset with this rule, some of them are
typeset as cautionaries.
pianomodern style, but here
accidentals also get canceled across the staves in the same

cancellations of the final notes.

Dodecaphonic-style accidentals for each note including naturals
In early 20th century works, starting with Schoenberg, Berg and Webern (the "Second" Viennese school), every pitch in the twelve-tone scale has to be regarded as equal, without any hierarchy such as the classical (tonal) degrees. Therefore, these composers print one accidental for each note, even at natural pitches, to emphasize their new approach to music theory and language.
This snippet shows how to achieve such notation rules.

Simultaneous notes are considered to be entered in sequential
mode. This means that in a chord the accidentals are typeset as
if the notes in the chord happen one at a time, in the order in
which they appear in the input file. This is a problem when
accidentals in a chord depend on each other, which does not happen
for the default accidental style. The problem can be solved by
manually inserting ! and ? for the
problematic notes.
The term ambitus (pl. ambitus) denotes a range of pitches for a given voice in a part of music. It may also denote the pitch range that a musical instrument is capable of playing. Ambitus are printed on vocal parts so that performers can easily determine if it matches their capabilities.
Ambitus are denoted at the beginning of a piece near the initial clef. The range is graphically specified by two note heads that represent the lowest and highest pitches. Accidentals are only printed if they are not part of the key signature.

Adding ambitus per voice
Ambitus can be added per voice. In this case, the ambitus must be moved manually to prevent collisions.

Ambitus with multiple voices
Adding the Ambitus_engraver to the Staff context creates
a single ambitus per staff, even in the case of staves with multiple
voices.

In shape note head notation, the shape of the note head corresponds to the harmonic function of a note in the scale. This notation was popular in nineteenth-century American song books. Shape note heads can be produced:
\aikenHeads
c, d e f g a b c
\sacredHarpHeads
c, d e f g a b c
Shapes are typeset according to the step in the scale, where the
base of the scale is determined by the \key command.
Applying note head styles depending on the step of the scale
The shapeNoteStyles property can be used to define various note
head styles for each step of the scale (as set by the key signature or
the "tonic" property). This property requires a set of symbols, which
can be purely arbitrary (geometrical expressions such as
triangle, cross, and xcircle are allowed) or based
on old American engraving tradition (some latin note names are also
allowed).
That said, to imitate old American song books, there are several
predefined note head styles available through shortcut commands such as
\aikenHeads or \sacredHarpHeads.
This example shows different ways to obtain shape note heads, and demonstrates the ability to transpose a melody without losing the correspondence between harmonic functions and note head styles.

This section discusses rhythms, rests, durations, beaming and bars.
Durations are designated by numbers and dots.
Durations are entered as their reciprocal values. For example, a
quarter note is entered using a 4 (since it is a 1/4 note),
and a half note is entered using a 2 (since it is a 1/2
note). For notes longer than a whole you must use the
\longa (a double breve) and \breve commands.
Durations as short as 64th notes may be specified. Shorter values
are possible, but only as beamed notes.
\time 8/1
c\longa c\breve c1 c2
c4 c8 c16 c32 c64 c64
Here are the same durations with automatic beaming turned off.
\time 8/1
\autoBeamOff
c\longa c\breve c1 c2
c4 c8 c16 c32 c64 c64
A note with the duration of a quadruple breve may be entered with
\maxima, but this is supported only within ancient music
notation. For details, see Ancient notation.
If the duration is omitted, it is set to the previously entered duration. The default for the first note is a quarter note.
a a a2 a a4 a a1 a
To obtain dotted note lengths, place a dot (.) after the
duration. Double-dotted notes are specified by appending two
dots, and so on.
a4 b c4. b8 a4. b4.. c8.
Some durations cannot be represented with just binary durations and dots; they can be represented only by tying two or more notes together. For details, see Ties.
For ways of specifying durations for the syllables of lyrics and ways of aligning lyrics to notes, see Vocal music.
Optionally, notes can be spaced strictly proportionately to their duration. For details of this and other settings which control proportional notation, see Proportional notation.
Dots are normally moved up to avoid staff lines, except in polyphonic situations. Predefined commands are available to force a particular direction manually, for details see Direction and placement.

\dotsDown,

There is no fundamental limit to rest durations (both in terms of longest and shortest), but the number of glyphs is limited: rests from 128th to maxima (8 x whole) may be printed.
Tuplets are made from a music expression by multiplying all the durations with a fraction:
\times fraction { music }
The duration of 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.
a2 \times 2/3 { b4 b b }
c4 c \times 2/3 { b4 a g }
The automatic placement of the tuplet bracket above or below the notes may be overridden manually with predefined commands, for details see Direction and placement.
Tuplets may be nested:
\autoBeamOff
c4 \times 4/5 { f8 e f \times 2/3 { e[ f g] } } f4 |
Modifying nested tuplets which begin at the same musical moment
must be done with \tweak.
To modify the duration of notes without printing a tuplet bracket, see Scaling durations.
\tupletUp,
\tupletDown,
\tupletNeutral.
Entering several tuplets using only one \times command
The property tupletSpannerDuration sets how long each of the
tuplets contained within the brackets after \times should last.
Many consecutive tuplets can then be placed within a single
\times expression, thus saving typing.
In the example, two triplets are shown, while \times was
entered only once.
For more information about make-moment, see "Time
administration".
\relative c' {
\time 2/4
\set tupletSpannerDuration = #(ly:make-moment 1 4)
\times 2/3 { c8 c c c c c }
}
Changing the tuplet number
By default, only the numerator of the tuplet number is printed over the
tuplet bracket, i.e., the denominator of the argument to the
\times command. Alternatively, num:den of the tuplet number may
be printed, or the tuplet number may be suppressed altogether.
\relative c'' {
\times 2/3 { c8 c c } \times 2/3 { c8 c c }
\override TupletNumber #'text = #tuplet-number::calc-fraction-text
\times 2/3 { c8 c c }
\override TupletNumber #'stencil = ##f
\times 2/3 { c8 c c }
}
Permitting line breaks within beamed tuplets
This artificial example shows how both manual and automatic line breaks may be permitted to within a beamed tuplet. Note that such off-beat tuplets have to be beamed manually.
\layout {
\context {
\Voice
% Permit line breaks within tuplets
\remove "Forbid_line_break_engraver"
% Allow beams to be broken at line breaks
\override Beam #'breakable = ##t
}
}
\relative c'' {
a8
\repeat unfold 8 { \times 2/3 { c[ b a] } }
% Insert a manual line break within a tuplet
\times 2/3 { c[ b \bar "" \break a] }
\repeat unfold 2 { \times 2/3 { c[ b a] } }
c8
}

When the first note on a staff is a grace note followed by a
tuplet the grace note must be placed before the \times
command to avoid errors. Anywhere else, grace notes may be
placed within tuplet brackets.
You can alter the duration of single notes, rests or chords by a
fraction N/M by appending *N/M (or *N if
M is 1) to the duration.
This will not affect the appearance of the notes or rests
produced, but the altered duration will be used in calculating the
position within the measure and setting the duration in the MIDI
output. Multiplying factors may be combined such as *L*M/N.
In the following example, the first three notes take up exactly two beats, but no triplet bracket is printed.
\time 2/4
% Alter durations to triplets
a4*2/3 gis4*2/3 a4*2/3
% Normal durations
a4 a4
% Double the duration of chord
<a d>4*2
% Duration of quarter, appears like sixteenth
b16*4 c4
The duration of skip or spacing notes may also be modified by
a multiplier. This is useful for skipping many measures, e.g.,
s1*23.
Longer stretches of music may be compressed by a fraction in the same way, as if every note, chord or rest had the fraction as a multiplier. This leaves the appearance of the music unchanged but the internal duration of the notes will be multiplied by the fraction num/den. The spaces around the dot are required. Here is an example showing how music can be compressed and expanded:
\time 2/4
% Normal durations
<c a>4 c8 a
% Scale music by *2/3
\scaleDurations #'(2 . 3) {
<c a f>4. c8 a f
}
% Scale music by *2
\scaleDurations #'(2 . 1) {
<c' a>4 c8 b
}
One application of this command is in polymetric notation, see Polymetric notation.

A tie connects two adjacent note heads of the same pitch. The tie in effect extends the duration of a note.
| Note: Ties should not be confused with slurs, which indicate articulation, or phrasing slurs, which indicate 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 ~
e'2 ~ e'
Ties are used either when the note crosses a bar line, or when dots cannot be used to denote the rhythm. Ties should also be used when note values cross larger subdivisions of the measure:
If you need to tie many notes across bar lines, it may be easier to use automatic note splitting, see Automatic note splitting. This mechanism automatically splits long notes, and ties them across bar lines.
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 the chord.
<c e g> ~ <c e g>
<c~ e g~ b> <c e g b>
When a second alternative of a repeat starts with a tied note, you have to specify the repeated tie as follows:
\repeat volta 2 { c g <c e>2 ~ }
\alternative {
% First alternative: following note is tied normally
{ <c e>2. r4 }
% Second alternative: following note has a repeated tie
{ <c e>2\repeatTie d4 c } }
