Re: string harmonics with cue notes

[Klaus Blum]

Hi Orm, 

not a complete solution, but maybe a start for further ideas...

You could define a variable to sum up all the formatting commands:

% -------------------------------------------------------------
\version "2.19.5"

cueNote = {
  \override ParenthesesItem.padding = #0.2
  \override ParenthesesItem.font-size = #1
  \once \override Stem.transparent = ##t
  \once \override NoteHead.font-size = #-3
  \once \override NoteHead.X-offset = #0.5
}

{
  <<
    {a'1 \harmonic ^"sul D"} \\ {\cueNote \parenthesize a''4}
  >>
}
% -------------------------------------------------------------

I've also experimented with avoiding the creation of a second voice:
However, there are two drawbacks:
1. Tweaking the notehead requires another function.
2. As both notes "live" in the same chord, you'll get a stem for other than
whole notes.
In both cases, I don't know how to avoid that. Maybe someone else could
chime in here?  ;-)
Anyway, here we go:

% -------------------------------------------------------------
\version "2.19.5"

#(define ((note-head-musicglyph name) grob)
   (grob-interpret-markup grob (make-musicglyph-markup name)))

{
  \once \override ParenthesesItem.padding = #0.3
  \once \override ParenthesesItem.font-size = #-1
  < a' \harmonic
  \parenthesize
  \tweak font-size #-3
  \tweak #'stencil #(note-head-musicglyph "noteheads.s2")
  %\tweak X-offset #0.5
  a''
  >1 ^\markup { "sul D" }
}
% -------------------------------------------------------------

Okay, this looks even worse, but again, you can abbreviate the formatting
stuff:

% -------------------------------------------------------------
\version "2.19.5"

#(define ((note-head-musicglyph name) grob)
   (grob-interpret-markup grob (make-musicglyph-markup name)))

cueNote = #(define-music-function (parser location cue) (ly:pitch?)
             #{
               \parenthesize
               \tweak font-size #-3
               \tweak Accidental.font-size #-3
               \tweak stencil #(note-head-musicglyph "noteheads.s2")
               %\tweak X-offset #0.5
               $cue
             #})

{
  \override ParenthesesItem.padding = #0.3
  \override ParenthesesItem.font-size = #-1
  < a' \harmonic \cueNote a'' >1 ^"sul D"
  < g' \harmonic \cueNote d''' >
  < fis' \harmonic \cueNote fis''' >
}
% -------------------------------------------------------------

In any case, you could replace \parenthesize by \parentheAll from
