Btw, sometimes the bracket completely disappears, but I haven't been
able to make a small example with that.

quartertriplet = { \set tupletSpannerDuration = #(ly:make-moment 1 4) }
\relative { \time 3/4 \clef treble \key g \minor
\relative c'' {
\times 2/3 { r8 a r a r4} r4 | r8 g r g r4 |
\times 2/3 { r8 a r a r4} r4 | r8 bes r bes r4 |
\times 2/3 { r8 c r c r4} r4 | r8 bes r bes r4 |
\times 2/3 { r8 a r a r a} r8 a | r4. g |
\version "2.9.27"

Same output with 2.9.something and 2.10.

Hi Victor,

With regards to the disappearing tuplet bracket, is it possible that
the bracket goes away when the enclosed figure beams completely? By
default, Lily will print only a TupletNumber (and not a TupletBracket)
when the enclosed music beams completely.

You can force the TupletBracket to print with

 \once \override TupletBracket #'bracket-visibility = ##t

immediately before any \times statement. If you always want to force
TupletBrackets in all places, include the \override (minus the \once)
in the \with block of your current context (Voice, Staff, Score or

As far as the 'jumping' brackets in the example, it looks like Lily
determines the tuplet bracket position (either up or down) based on
the stem direction of the first note in the figure ... with the
additional rule that tuplet figures beginning in a rest cause the
tuplet direction to equal down.

With the example above, probably the easiest thing to do is to force
tuplet bracket direction with

 \override TupletBracket #'direction = #down


 \override TupletBracket #'direction = #up

depending on preference. When you want Lily to resume dynamically
positioning the tuplet bracket direction, just write

 \revert TupletBracket #'direction
