RE: Problems with automatic beaming when autoBeamOff in 3/8 time

[Trevor Daniels]

Hi Reinhold

As the two types of bar have different sub-beats there is
no way to do this automatically with just a single setting,
AFAIK - every time the sub-beating changes the new
beatLength will have to be indicated - just as if you were
changing the time signature.  You already know the
overrides to do this:

\set Score.beatLength = #(ly:make-moment 2 16)
\set Score.beatLength = #(ly:make-moment 3 16)

The commands can be set as short-name variables, and they
apply score-wide, so only need to be placed in one staff,
like this:

Two =   \set Score.beatLength = #(ly:make-moment 2 16)
Three = \set Score.beatLength = #(ly:make-moment 3 16)

\relative c'' {
  \autoBeamOff
  \time 3/8
  \key g \major
  d8[ c16( b a g)] |
  \Three g8.[ fis16( e d)] |
  \Two d8[ c16( b a g)] |
  % Two measures later:
  b'16.([ c32) d16] g[( d b])
}

although personally I would have a separate timing variable
in parallel with the music to hold these changes and
anything
else to do with timing.
