I also notice that when I turn off the beamExceptions the beaming
goes a
bit haywire. Have a look at bars 5 and 6 after I have used \set
beamExceptions = #'():
This is due to erroneous ly input; see below:
\version "2.13.29"
changeBeamingA = \overrideTimeSignatureSettings
#'Score
#'(2 . 4) % time signature fraction
#'(1 . 8) % base moment fraction
#'(1) % beatStructure
This should be
#'(1 1 1 1) % base moment fraction
if you want beams grouped in quavers else only
the first 1/8 is a separate beam group.
Or, if you want the default to beam the whole bar you need
#'(1 . 2) % base moment fraction
#'(1) % beatStructure
#'((end . (((1 . 16) . (2 2 2 2))
((1 . 24) . (3 3 3 3))
((1 . 32) . (4 4 4 4))
((1 . 48) . (6 6 6 6))))) % beamExceptions
changeBeamingB = \set beamExceptions =
#'((end . (((1 . 16) . (2 2 2 2))
((1 . 24) . (3 3 3 3))
((1 . 32) . (4 4 4 4))
((1 . 48) . (6 6 6 6))))) % beamExceptions
revertBeaming = \set beamExceptions = #'()
\relative c'' {
\set tupletSpannerDuration = #(ly:make-moment 1 8)
\changeBeamingA
\time 2/4
\repeat unfold 8 c16
\times 2/3 { \repeat unfold 12 c16 }
\repeat unfold 16 c32
\times 4/6 { \repeat unfold 24 c32 }
\revertBeaming
\break \repeat unfold 8 c16 \repeat unfold 16 c32
\changeBeamingB
\repeat unfold 8 c16
\times 2/3 { \repeat unfold 12 c16 }
\repeat unfold 16 c32
\times 4/6 { \repeat unfold 24 c32 }
}
