Re: proportional horizontal space in accelerando and ritardando

[Pierre Perol-Schneider]

Oops my fault.

So here it goes:

\version "2.19.35"

\relative c'' {
  \set Score.proportionalNotationDuration = #(ly:make-moment 1/40)
  \override Beam.grow-direction = #RIGHT
  \featherDurations #(ly:make-moment 2/3)
  { e32[ 
    \override NoteHead.transparent = ##t
    e e e e e e e e e e e e e e]
  }
 
  \override Beam.grow-direction = #LEFT
  \featherDurations #(ly:make-moment 3/2) %% <= !!!
  { e32[ e e e e e e e e e e e
    \revert NoteHead.transparent
    e]
  }
  \override Beam.grow-direction = #'()
  s8
}

Cheers,

Pierre

Hi Caio, Hi Malte,

Well there's something strange here: proportional duration seems to work in one feather direction only:

\version "2.19.35"

\relative c'' {
  \set Score.proportionalNotationDuration = #(ly:make-moment 1/40)
  \override Beam.grow-direction = #RIGHT
  \featherDurations #(ly:make-moment 2/3)
  { e32[ 
    \override NoteHead.transparent = ##t
    e e e e e e e e e e e e e e]
  }
 
  %%%% 'proportionalNotationDuration' has no effect here (bug?):
  \override Beam.grow-direction = #LEFT
  { e32[ e e e e e e e e e e e
    \revert NoteHead.transparent
    e]
  }
  \override Beam.grow-direction = #'()
  s8
}

Any idea why ?

Cheers,

Pierre

This is already implemented; see section 1.2.4 of the notation reference
(this is called “feathered beams”).
