Re: autobeams

[Jonathan Kulp]

I had a similar problem with an example I was working on for GDP 
Rhythms, in Notation Reference 1.2.6.2.  If you look at that example, 
you can see that there's a whole series of 8ths that ought to be 
autobeamed but are not.  I couldn't even make them beam properly 
manually.  I ended up sidestepping the issue and removing the extra 
voice, since that example is only meant to show how to make another part 
in a different staff begin at the right place after a cadenza.   I don't 
know why the author of it introduced the complexity of multiple voices 
in that context.

Regarding your example, there were two ways I could get it to beam those 
last two 8ths automatically. One was to move the C in the final chord of 
the bar to the upper voice and allow the multiple-voice passage to last 
for the entire bar, rather than for only the first three beats.  Here:

\version "2.11.55"
\relative { \clef bass << {e8 d d c d8 c c4 } \\ {  <c g>4 g <b f>4 <f 
a> } >>  }

This makes the beaming work, and all the notes are the same, but it does 
not preserve the original intent of having the final chord <f a c> all 
in the lower voice.   I'm sure you found that you could manually beam 
the "d8[ c]" but it doesn't seem like you should have to.

The other way was to leave the <f a c> chord intact in the lower voice, 
but put it inside the multi-voice << >> and add a quarter-note skip to 
the upper voice:

\version "2.11.55"
\relative { \clef bass << {e8 d d c d8 c s4 } \\ {  <c g>4 g <b f>4 <f a 
c> } >>  }

This does seem like a workaround, though, as it looks like something 
that ought to work exactly the way you had it the first time.  Anyone 
else see what the problem could be?

Best,

Jonathan
