Actually, no. What is needed is a correct value for the beatGrouping
;-) You
don't want 3 eighth notes to be beamed together, do you? You want the
beams to
be broken after EACH eighth note. So the correct value is to set beat
Grouping
to #'(1 1 1 1 1 1 ), which tells lilypond to beam together all
subdivisions of
an eighth note, but don't beam across eighth note boundaries.
So, your complete example would be:
\transpose c c'' {
\clef treble
\time 6/8
\repeat volta 2 {
\set Score.beatGrouping = #'(1 1 1 1 1 1)
\times 2/3 { bes16 g es }
\override TupletNumber #'stencil = ##f
\repeat unfold 5 { \times 2/3 { bes16 g es } } |
\repeat unfold 6 { \times 2/3 { bes16 as es } } |
}
}
