proportional horizontal space in accelerando and ritardando

2016-01-26 Thread Caio Giovaneti de Barros 
Here's a problem more or less common in contemporary music notation (and 
very common in contemporary me, right now)


In some pieces of music it's common to reflect accelerandos and 
ritardandos by proportionally increasing and decreasing (respectively) 
the distance between notes.


Here is an example, after a quick search:

What do you think would be the best way to implement this in Lilypond?

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

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

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

You are right. I guess after 4 hours of music editing my brain went on 
strike
