Comment #4 on issue 2361 by address@hidden: Beams with multiple  
subdivisions
https://code.google.com/p/lilypond/issues/detail?id=2361

LilyPond's beam subdivision was clearly wrong when compared with Gould.   
That error has been made a separate issue (issue 4355) and a patch has been  
submitted.

In this music there are two levels of subdivision.  There is a subdivision  
at the 1/8 note level, and one at the 1/16 note level.  The first 1/8 note  
is connected by a single beam two a two-note group with a duration of 1/16  
note.  This group is connected by a double beam to another two-note group  
with a duration of 1/16.  Then, as we are at the end of a 1/8 duration, we  
are connected with a single beam to the next 1/16 note group.

The current logic of lilypond's beam subdivision allows us to choose to  
subdivide at only a single level.  So we cannot get the desired beaming.   
Instead we get either a single beam between 1/8 note groups (and no other  
subdivision), or a double beam between 1/16 note groups (and no other  
subdivision).  The enhancement request (which will require some kind of  
syntax change) is to allow more than one level of subdivisions.
