Re: Better way to get correct slur shapes?

[Stefano Troncaro]

Hi Knute, Simon,

A little question if you don't mind, what is the override to NoteColumn.ignore-collision for? I took it out of your example and I don't see a difference in the results.

Thanks Simon, that's a great tool.

I changed the function just a bit so that the stems of the eighth notes in the lower voices aren't so long:

%%%%

dummy =

#(define-music-function (mus) (ly:music?)

   #{

     \override NoteColumn.ignore-collision = ##t

     \voiceTwo

     \once \omit Stem

     \once \omit Flag

     $mus

     \revert NoteColumn.ignore-collision

     \voiceOne

   #})

%%%%

Hi Knute,

how about this?

%%%%%%%%%%%%%%%%%%%%
\version "2.19.80"
\language "english"

dummy =
#(define-music-function (mus) (ly:music?)
   #{
     \hideNotes
     \override NoteColumn.ignore-collision = ##t
     \voiceTwo
     $mus
     \unHideNotes
     \revert NoteColumn.ignore-collision
     \voiceOne
   #})

\relative {
  \time 6/8
  \key g \minor

  r8 << { <df'' f>4*1/2( \dummy f,8) } \\ { af8 f } >>

  r8 << { <ef' g>4*1/2( \dummy g,8) } \\ { bf8 g } >> |
}
%%%%%%%%%%%%%%

I think, the slur shapes Lily chooses there are quite neat.

Best, Simon

I have a slurring problem that's not terribly difficult to solve, but I'm wondering if there's a better way to do it. Here's my example:

%%%
\version "2.19"
\language "english"

slurShapeA = \shape #'((0.75 . 2) (0.5 . 1.5) (0.33 . 1) (0.25 . 0)) \etc

\relative {
  \time 6/8
  \key g \minor
  % Could something like this work?
  r8 << { <df'' f>4 } \\ { af8 f } \\ { \voiceTwo \hideNotes f'8 ^( f, ) } >>
  % This works, but it's tedious and brittle
  r8 << { <ef' g>4 } \\ { bf8 -\slurShapeA ^( g ) } >> |
}
%%%

In the piece I'm engraving there are dozens of this kind of slurs.  In the second half of the measure, I've used the \shape function to modify the slur between the two eighth notes to look like it starts at the quarter note in the other voice. I can do it this way, but it will take dozens of shapes, all controlled manually.  This is a tedious and brittle solution, because any change in the page layout that affects how the measures are spaced may change all the slur shapes (like switching from letter size to A4).

So I was hoping I could use some hidden notes in a third voice to make the slur, but as you can see from the first half of the measure, it's not going very well.  Can this or some other solution work?
