Re: Beams over rests and concaveness

    Hi everyone,
    
    It seems that the beam concaveness value is ignored when beaming over rests,
    in the case of a single note with a single rest. This happens with and
    without stemlet. See the code and score below, the groups marked with an
    asterisk should have been flat (+inf.0 concaveness): 
    
    Does anyone know a solution for this?

I think this is a bug, and should be reported as such.  Neither concaveness nor 
damping works to set the beam horizontal in this case.

There is a workaround -- set the beam positions yourself.  The rest will move 
as needed to have the right relationship with the beam:

\version "2.19.82"
{
  \time 12/8
  g8[ g'8]
  \once \override Beam.concaveness = #+inf.0
  g8[ g'8]
  
  g8[ r8]
 \once \override Beam.positions=#`(0 . 0)
  g8[ r8]^"*"
  
  \override Stem.stemlet-length = #1
  g8[ r8]
 \once \override Beam.positions=#`(0 . 0)
  g8[ r8]^"*"
  
}
    

Hope this helps,

Carl
