Lilypond does not currently do "second-level" beam subdivisions.

Please add this as a feature request.  I have been looking for a good
example of what it means to have multiple subdivision.

I believe this can be achieved; I will try to get to it in the next couple
of weeks.

I believe this beaming could be expressed as something like:

(subdivide . ((1 . 8) . (1 1 1))
             ((1 . 16) . (1 1 1 1 1 1)))

although I am not proposing this as the syntax.

It might be better to change subdivideBeams from a boolean to a list,
where each element of the list would be a beat length at which to
subdivide.  If that were the case we would achieve the beaming in the
sample by

\set subdivideBeams = #'((1 . 8) (1 . 16))

Or perhaps

\set subdivideBeams = #'((ly:make-moment 1 8)
                         (ly:make-moment 1 16))

Or perhaps even (with David K's new syntax, where we can have duration
elements)

\set subdivideBeams = #'( 8 16 )

I'll put this in the hopper and think about it.

Thanks,

Carl
