Re: Pitched trill glissando

[Pierre Perol-Schneider]

David,

did you notice Harm's pointed the elegant way I was looking for ?

Addapted to your code it goes :

\version "2.19.13"

parentGrace = #(define-music-function (parser loc myGrace ) (ly:music?)
#{
  \once \override NoteHead.X-offset = #-.5
  \once \omit Staff.Flag
  \once \omit Staff.Stem
  \once \override ParenthesesItem.font-size = #-1
  \once \override ParenthesesItem.stencil = #(lambda (grob)
       (let* ((acc (ly:grob-object (ly:grob-parent grob Y) 'accidental-grob))
              (dot (ly:grob-object (ly:grob-parent grob Y) 'dot)))
         (if (not (null? acc)) (ly:pointer-group-interface::add-grob grob 'elements acc))
         (if (not (null? dot)) (ly:pointer-group-interface::add-grob grob 'elements dot))
         (parentheses-item::print grob)))
  \parenthesize $myGrace
#})

{
  \clef "altovarC"
  \pitchedTrill c2\startTrillSpan
   -\tweak minimum-length #10
  -\tweak springs-and-rods #ly:spanner::set-spacing-rods
  -\tweak bound-details.left.Y #-3.25
  -\tweak bound-details.right.Y #-2.75
  -\tweak bound-details.left.padding #3.5
  -\tweak bound-details.right.padding #.8
  \glissando ~ des
  \grace {  \parentGrace d8 }
  c8\stopTrillSpan r8
}

Thank you Harm ;)

Cheers,
Pierre

Thanks Pierre,

This seems to work perfectly in the score I'm working on.

All the best,

David

Hi David,

my first idea was to change the grace note head stencil but, for some reason, I cannot change the ledger lin length:

parentGrace = {
  \once\omit Flag
  \once\omit Stem
  \once\omit Accidental
  \once\override NoteHead.stencil = #(lambda (grob)
                                  (grob-interpret-markup grob
                                    #{
                                      \markup\concat\fontsize #-1  {
                                        \musicglyph #"accidentals.leftparen"
                                        \hspace #.3
                                        \musicglyph #"accidentals.natural"
                                        \hspace #.2
                                        \musicglyph #"noteheads.s2"
                                        \hspace #.2
                                        \musicglyph #"accidentals.rightparen"
                                      }
                                    #}
                                    ))
}

{
  \clef "altovarC"
  %{
    \once \override Glissando.minimum-length = #10
    \once \override Glissando.springs-and-rods = #ly:spanner::set-spacing-rods
    \once \override Glissando.bound-details.left.Y = #-3.25
    \once \override Glissando.bound-details.right.Y = #-2.75
    \once \override Glissando.bound-details.left.padding = #3.5
    \once \override Glissando.bound-details.right.padding = #.8
  %}
  \pitchedTrill c2\startTrillSpan
  %% shorter syntax:
  %-\tweak minimum-length #8 % <= for a similar note to note distance
  -\tweak minimum-length #10
  -\tweak springs-and-rods #ly:spanner::set-spacing-rods
  -\tweak bound-details.left.Y #-3.25
  -\tweak bound-details.right.Y #-2.75
  -\tweak bound-details.left.padding #3.5
  -\tweak bound-details.right.padding #.8
  \glissando ~ des
  \parentGrace
  \grace { d8 }
  c8\stopTrillSpan r8
}

So I finally change my mind for grace's accidental :

parentAccidental = {
  \once\omit Flag
  \once\omit Stem
  \once\override NoteHead.X-offset = #-.5
  \once\override Accidental.extra-offset = #'(1.9 . 0)
  \once\override Accidental.stencil = #(lambda (grob)
                                  (grob-interpret-markup grob
                                    #{
                                      \markup\concat  {
                                        \musicglyph #"accidentals.leftparen"
                                        \hspace #.3
                                        \musicglyph #"accidentals.natural"
                                        \hspace #1.4
                                        \musicglyph #"accidentals.rightparen"
                                      }
                                    #}
                                    ))
}

{
  \clef "altovarC"
  \pitchedTrill c2\startTrillSpan
  -\tweak minimum-length #10
  -\tweak springs-and-rods #ly:spanner::set-spacing-rods
  -\tweak bound-details.left.Y #-3.25
  -\tweak bound-details.right.Y #-2.85
  -\tweak bound-details.left.padding #3.5
  -\tweak bound-details.right.padding #-1.6
  \glissando ~ des
  \parentAccidental
  \grace { d8 }
  c8\stopTrillSpan r8
}

I bet that some more elegant solutions exist but I don't see any right now.

Pierre

Hi list,

I'm trying to create a pitched trill where the parenthesized note glisses to a new note.

I've got quite close to the notation I'm after, but I can't find a way to parenthesize the goal note the same way as the pitchedTrill. \parenthesize doesn't seem to include the accidental, and is in a different style to pitchedTrill. Any ideas?

Thanks!

Best,

David
