Re: Stemless music with slurs

[Juergen Reuter]

I think the following does *almost* what you want (only almost, because 
you get harmonic note heads instead of quarter note heads):


\version "2.7.17"

#(define-public (note-head::calc-glyph-name grob) "2")

barOne = { \once \override Staff.BarLine #'bar-size = #2
           \bar "|" }
barTwo = { \once \override Staff.BarLine #'extra-offset = #'(0 . 2)
           \once \override Staff.BarLine #'bar-size = #2
           \bar "|" }

chant = \relative c' {
  \set Staff.autoBeaming = ##f
  \set Score.timing = ##f
  \key f \major
  \mark \markup {Antiphon \hspace #2 \italic{"Ps. 29"} }
  \override Staff.NoteHead #'style = #'harmonic
  \slurUp
  f1 g( a) f( d) f( g f1.) \barTwo
  f1 g( a) a1. \barOne
  a1 f g a c( d c) c1. \barTwo
  f,1( g) a( g) a f( g f1.) \bar "||"
}

text = \lyricmode {
  The Lord will reign
  for e -- ver;
  and will give his peo -- ple
  the gift of peace.
}

\score {
  <<
    \new Staff {
      \chant
    }
%    \lyricsto "staff" \new Lyrics { \text }
  >>
  \layout {
    indent = 0
  }
}



The only thing that does _not_ work here is the "define-public" definition 
at the very top: it has no effect.  It is supposed to replace the 
definition in scm/output-lib.scm, such that you always get quarter note 
heads, but it does not seem to be possible to override this definition (or 
do I miss something?).  If you directly modify output-lib.scm accordingly, 
than it perfectly works.  (Ideally, you probably would like to patch lily 
such that you can say something like "\override Staff.NoteHead #'style = 
#'4" or "\override Staff.NoteHead #'style = #'default4".)

The basic idea here is to use stemless whole note durations and override 
NoteHead style such that whole notes are printed with quarter note heads.
