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] |

a8 a16 a a8 a16 a
a8 a16 a a8 a16 a | % wrong, should be ...
a8[ a16 a] a8 a16 a
a8[ a16 a] a8 a16 a |

a32 a a16 a a a a32 a a16 a
a a a32 a a16 a a a a32 a | % wrong, should be ...
a32[ a a16 a a] a[ a32 a a16 a]
a[ a a32 a a16] a a a a32 a
}
