Thank you both, very helpful!

Setting beam damping to a high value reduces the slope substantially, 
but it doesn't go to zero. Can someone suggest a way to do this?


\version "2.20.0"
{ \override Beam.damping = #5
  g''8 b b c'' c'' b b g'' }

Hello,

\override Beam.damping = #+inf.0 is supposed to do the trick. A bug that 
used to prevent it from working in all cases (not this one though) was 
fixed in version 2.21.0 
(https://gitlab.com/lilypond/lilypond/-/issues/1493).


{
  \override Beam.damping = #+inf.0
  g''8 b b c'' c'' b b g''
}

Best,
Jean

Hi Ahanu,

And for an automated approach:

#(define NEAR -1)

flattenPositions =

  \override Beam.positions = \flattenPositions #(* 2 FAR)

Hi Ahanu,
How about:

\version "2.20.0"
{
  %\override Beam.damping = #5
  \override Beam.positions = #'(5 . 5)
  g''8 b b c'' c'' b b g''
}

Cheers,

Horizontal beam parallel to staff

[Ahanu Banerjee]

I know it is not standard practice, but I am looking for a way to make
beams parallel to staff despite the noteheads on either side of the beam
having different vertical positions on the staff.

Setting beam damping to a high value reduces the slope substantially, but
it doesn't go to zero. Can someone suggest a way to do this?

\version "2.20.0"
{ \override Beam.damping = #5
  g''8 b b c'' c'' b b g'' }


Thanks,
