Could the two of you please take some of these examples and beam
them
manually so that I can see what they *should* do? I'll then try
to figure
out why the autobeam engraver doesn't do it.
Some explanation as to *why* it should work the way it should
would also be
helpful.
There is no fixed rule for beaming in 4/4.
Beams ending at 1/2 are often used, as are
beams ending at 1/4, 1/2 and 3/4. Whichever
is chosen, the beaming must be consistent
throughout the bar. There are two issues:
a) the default beaming rules are not optimum, and
b) it is not possible to find beaming rules that
beam certain groupings consistently. The
following examples illustrate the problems.
\relative c'' {
a8 a a a a a a a | % OK
a16 a a8 a a
a a16 a a8 a | % wrong, should be ...
a16[ a a8] a a
a[ a16 a] a8 a |
a8 a a16 a a8
a a a a16 a | % wrong, should be ...
a8 a a16[ a a8]
a a a[ a16 a] |

a32[ a a16 a a] a[ a32 a a16 a]
a[ a a32 a a16] a a a a32 a
