Problem with partcombine and shape notes

[Bumby Hymnal]

I've run into a problem with using \partcombine while using \aikenHeads.  The
problem is that under certain circumstances the aiken shape note heads are
not used in the output of \partcombine.  The strange thing is that it
sometimes works.  The following snippet shows 4 different voices.  The
first voice is a basic scale.  The 2nd voice is exactly the same.  The
third voice is a third below the first voice, and the fourth voice
alternates between being unison and being a 3rd apart from the first voice.
Each voice is rendered independently and shows the shape notes properly.  Then
the first voice is combined with the 2nd (identical), then the 3rd (down a
3rd), and the 4th (alternating unison then a third).  The first two cases
render the shape notes properly.  The last case of with alternating unison
/ 3rds produces proper shape notes when unison, but normal (non shape)
notes when rendered as a chord.



SNIPPET:



\version "2.19.49"



firstVoice  = \relative c' { \aikenHeads c4 d e f g a b c }

sameVoice   = \relative c' { \aikenHeads c4 d e f g a b c }

thirdVoice  = \relative c' { \aikenHeads a4 b c d e f g a } fourthVoice =
\relative c' { \aikenHeads c4 b e d g f b a }



<<

  \new Staff \with { instrumentName = "firstVoice"  } \firstVoice

  \new Staff \with { instrumentName = "sameVoice"   } \sameVoice

  \new Staff \with { instrumentName = "thirdVoice"  } \thirdVoice

  \new Staff \with { instrumentName = "fourthVoice" } \fourthVoice

  \new Staff \with { instrumentName = "unison"  } \partcombine #'(2 .
12) \firstVoice \sameVoice

  \new Staff \with { instrumentName = "thirds"  } \partcombine #'(2 .
12) \firstVoice \thirdVoice

  \new Staff \with { instrumentName = "mix" } \partcombine #'(2 .
12) \firstVoice \fourthVoice

\version "2.19.49"

firstVoice  = \relative c' { \aikenHeads c4 d e f g a b c }
sameVoice   = \relative c' { \aikenHeads c4 d e f g a b c }
thirdVoice  = \relative c' { \aikenHeads a4 b c d e f g a }
fourthVoice = \relative c' { \aikenHeads c4 b e d g f b a }

Thank you for your thorough response.  That worked great - and I now have a
better understanding of how things work.

How to control how extra horizontal space is distributed when ragged_right is false

[Bumby Hymnal]

Hello,

I've been working on typesetting hymns, and part of our style is that we
want the systems to be full width (ragged_right is false), but we also
explicitly break systems on hymn phrase boundaries.  That means that we
often have more than a typical amount of extra white space available, which
lilypond then distributes between the various objects in the system.  My
problem is that I don't like the choices that lilypond is making and can't
figure out how to control it.

I've attached to clips from Abide With Me to illustrate the problem.  These
are clips of the top half of one system; one with ragged_right false; and
one with ragged_right true.

It all looks good when ragged right is true - all the notes and lyrics have
nice even separation and are easy to read.  When stretched to the full page
width, extra space is added, it seems, based upon the length of the notes -
so the half notes get more space than the quarter notes, and the whole note
gets more than all the rest.  What I'd most prefer is that the extra white
space is distributed between all the notes more evenly.  Some slight
preference based upon the length of the note is ok; but not nearly as much
as is occurring in this example.

Here are the layout overrides I'm currently using:

\layout {
  #(layout-set-staff-size 18)
  \context {
\Lyrics
\override LyricSpace.minimum-distance = #3
\override LyricText.font-size = #0
\override LyricText.self-alignment-X = #CENTER
\override LyricHyphen.thickness = #1
\override LyricHyphen.length = #1.0
\override VerticalAxisGroup.nonstaff-nonstaff-spacing =
#'((basic-distance . 0)
   (minimum-distance . 0)
   (padding . 0.85)
   (stretchability . 0))

  }
  \context {
\Staff
\override StaffSymbol.thickness = #1
\override NoteHead.font-size = #1
#(if MajorKey #{ \aikenHeads #} #{ \aikenHeadsMinor #})
  }
  \context {
\Score
\remove "Bar_number_engraver"
  }
}

Thanks in advance for any guidance you can give me.

Thank you very much.  I've spent alot of time in the first link you sent
with little luck.  But for some reason I've skipped over the overview.
That section is very well written, I must say.  It has helped
tremendously.  There are still problems I'd like to fix; but the ones based
upon note duration I think are largely past.  I'm now trying to figure out
how to reduce the extra spacing that seems to be based upon proximity to
bar lines.
