Tuplets
Tuplets are made from a music expression with the \tuplet
command, multiplying the speed of the music expression by a fraction:
\tuplet fraction { music }
The fraction’s numerator will be printed over or under the notes, optionally with a bracket. The most common tuplets are triplets (3 notes played within the duration normally allowed for 2).
\relative { a'2 \tuplet 3/2 { b4 4 4 } c4 c \tuplet 3/2 { b4 a g } }
When entering long passages of tuplets, having to write a separate
\tuplet
command for each group is inconvenient. It is possible
to specify the duration of one tuplet group directly before the music
in order to have the tuplets grouped automatically:
\relative { g'2 r8 \tuplet 3/2 8 { cis16 d e e f g g f e } }
Tuplet brackets may be manually placed above or below the staff:
\relative { \tupletUp \tuplet 3/2 { c''8 d e } \tupletNeutral \tuplet 3/2 { c8 d e } \tupletDown \tuplet 3/2 { f,8 g a } \tupletNeutral \tuplet 3/2 { f8 g a } }
Tuplets may be nested:
\relative { \autoBeamOff c''4 \tuplet 5/4 { f8 e f \tuplet 3/2 { e[ f g] } } f4 }
Modifying nested tuplets which begin at the same musical moment must be
done with \tweak
; see \tweak
and \single
.
Tuplet brackets may be replaced with slurs, as is preferred in many older editions:
\relative { \tuplet 3/2 4 { \override TupletBracket.tuplet-slur = ##t c'4 e8 d4 f8 \override TupletBracket.bracket-visibility = ##t e f g f e d } c1 }
By default, a bracket is only printed if all of the notes it spans
are not beamed together; in some cases (for example with slurs, as
in the example above) it may be preferable to change that behavior,
through the bracket-visibility
property as detailed in
one of the following snippets.
More generally, either or both the TupletBracket
and
TupletNumber
objects may be hidden or shown as explained in
Visibility of objects; however, a more flexible way of
modifying the duration of notes without printing a tuplet
bracket is also introduced in Scaling durations.

Selected Snippets
Entering several tuplets using only one \tuplet command
The property tupletSpannerDuration
sets how long each of the
tuplets contained within the brackets after \tuplet
should
last. Many consecutive tuplets can then be placed within a single
\tuplet
expression, thus saving typing.
There are several ways to set tupletSpannerDuration
. The
command \tupletSpan
sets it to a given duration, and clears it
when instead of a duration \default
is specified. Another way
is to use an optional argument with \tuplet
.
\relative c' { \time 2/4 \tupletSpan 4 \tuplet 3/2 { c8^"\\tupletSpan 4" c c c c c } \tupletSpan \default \tuplet 3/2 { c8^"\\tupletSpan \\default" c c c c c } \tuplet 3/2 4 { c8^"\\tuplet 3/2 4 {...}" 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 numerator of the argument to the
\tuplet
command.
Alternatively, num:den of the tuplet number may be printed, or the tuplet number may be suppressed altogether.
\relative c'' { \tuplet 3/2 { c8 c c } \tuplet 3/2 { c8 c c } \override TupletNumber.text = #tuplet-number::calc-fraction-text \tuplet 3/2 { c8 c c } \omit TupletNumber \tuplet 3/2 { c8 c c } }
Non-default tuplet numbers
LilyPond also provides formatting functions to print tuplet numbers different than the actual fraction, as well as to append a note value to the tuplet number or tuplet fraction.
\relative c'' { \once \override TupletNumber.text = #(tuplet-number::non-default-tuplet-denominator-text 7) \tuplet 3/2 { c4. c4. c4. c4. } \once \override TupletNumber.text = #(tuplet-number::non-default-tuplet-fraction-text 12 7) \tuplet 3/2 { c4. c4. c4. c4. } \once \override TupletNumber.text = #(tuplet-number::append-note-wrapper (tuplet-number::non-default-tuplet-fraction-text 12 7) (ly:make-duration 3 0)) \tuplet 3/2 { c4. c4. c4. c4. } \once \override TupletNumber.text = #(tuplet-number::append-note-wrapper tuplet-number::calc-denominator-text (ly:make-duration 2 0)) \tuplet 3/2 { c8 c8 c8 c8 c8 c8 } \once \override TupletNumber.text = #(tuplet-number::append-note-wrapper tuplet-number::calc-fraction-text (ly:make-duration 2 0)) \tuplet 3/2 { c8 c8 c8 c8 c8 c8 } \once \override TupletNumber.text = #(tuplet-number::fraction-with-notes (ly:make-duration 2 1) (ly:make-duration 3 0)) \tuplet 3/2 { c4. c4. c4. c4. } \once \override TupletNumber.text = #(tuplet-number::non-default-fraction-with-notes 12 (ly:make-duration 3 0) 4 (ly:make-duration 2 0)) \tuplet 3/2 { c4. c4. c4. c4. } }
Controlling tuplet bracket visibility
The default behavior of tuplet-bracket visibility is to print a bracket unless there is a beam of the same length as the tuplet.
To control the visibility of tuplet brackets, set the property
bracket-visibility
to either #t
(always print a bracket),
if-no-beam
(only print a bracket if there is no beam) or
#f
(never print a bracket). The latter is in fact equivalent to
omitting the TupletBracket
object altogether from the printed
output.
music = \relative c'' { \tuplet 3/2 { c16[ d e } f8] \tuplet 3/2 { c8 d e } \tuplet 3/2 { c4 d e } } \new Voice { \relative c' { \override Score.TextMark.non-musical = ##f \textMark "default" \music \override TupletBracket.bracket-visibility = #'if-no-beam \textMark \markup \typewriter "'if-no-beam" \music \override TupletBracket.bracket-visibility = ##t \textMark \markup \typewriter "#t" \music \override TupletBracket.bracket-visibility = ##f \textMark \markup \typewriter "#f" \music \omit TupletBracket \textMark \markup \typewriter "omit" \music } } \paper { tagline = ##f }
Printing tuplet brackets on the note head side
Whichever option you choose for controlling the tuplet bracket
visibility, it will show or hide the tuplet bracket irrespectively of
tuplet bracket placement (stem side or note head side). However, when
placing the tuplet bracket on the note head side some authors recommend
always printing the tuplet bracket. The option
visible-over-note-heads
can be used to achieve this.
music = \relative c'' { \tupletNeutral \tuplet 3/2 { c16[ d e } f8] \tupletUp \tuplet 3/2 { c8 d e } } \new Voice { \relative c' { \time 2/4 \override TupletBracket.visible-over-note-heads = ##t \override Score.TextMark.non-musical = ##f { \textMark \markup "default" \music } \override TupletBracket.bracket-visibility = #'if-no-beam { \textMark \markup \typewriter "'if-no-beam" \music } } }
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.
\paper { tagline = ##f } \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 5 { \tuplet 3/2 { c[ b a] } } % Insert a manual line break within a tuplet \tuplet 3/2 { c[ b \bar "" \break a] } \repeat unfold 5 { \tuplet 3/2 { c[ b a] } } c8 }
