Modifying tuplet bracket length
Tuplet brackets can be made to run to prefatory matter or the next
note. Default tuplet brackets end at the right edge of the final note
of the tuplet; full-length tuplet brackets extend farther to the right,
either to cover all the non-rhythmic notation up to the following note,
or to cover only the whitespace before the next item of notation, be
that a clef, time signature, key signature, or another note. The
example shows how to switch tuplets to full length mode and how to
modify what material they cover.
\new RhythmicStaff {
% Set tuplets to be extendable...
\set tupletFullLength = ##t
% ...to cover all items up to the next note
\set tupletFullLengthNote = ##t
\time 2/4
\tuplet 3/2 { c4 4 4 }
% ...or to cover just whitespace
\set tupletFullLengthNote = ##f
\time 4/4
\tuplet 5/4 { 4 1 }
\time 3/4
2.
