Hallo,
I’d like to replace the arpeggioBracket by a curly bracket / brace.
Thank your for your help!
Here's a stencil callback reading the vertical start
and end positions of the arpeggio and printing a bracket
accordingly:
\version "2.22.1"
arpeggioBrace =
\tweak stencil
#(lambda (grob)
(let* ((positions (ly:grob-property grob 'positions))
(layout (ly:grob-layout grob))
(scale (ly:output-def-lookup layout 'output-scale))
(factor (/ scale (ly:pt 1)))
(len (* factor (+ 0.5 (interval-length positions))))
(brace-markup (make-left-brace-markup len))
(brace-stencil (grob-interpret-markup grob brace-markup)))
(ly:stencil-translate-axis brace-stencil
(interval-center positions)
Y)))
\arpeggio
\relative {
\clef bass
<e g b g'>\arpeggioBrace
}
Best,
Jean
Thank you Jean,
This is very nice!
How can I use this for connected arpeggios through voices?
These are a bit special because they are not created
from the \arpeggio events. Use \override rather than
\tweak in this case.
\version "2.22.1"
spanArpeggioBrace =
\once \override PianoStaff.Arpeggio.stencil =
#(lambda (grob)
(let* ((positions (ly:grob-property grob 'positions))
(layout (ly:grob-layout grob))
(scale (ly:output-def-lookup layout 'output-scale))
(factor (/ scale (ly:pt 1)))
(len (* factor (+ 0.5 (interval-length positions))))
(brace-markup (make-left-brace-markup len))
(brace-stencil (grob-interpret-markup grob brace-markup)))
(ly:stencil-translate-axis brace-stencil
(interval-center positions)
Y)))
\new PianoStaff \with {
connectArpeggios = ##t
}
<<
\new Staff \relative {
\spanArpeggioBrace
% Looks better a bit closer to the notes?
\once \override PianoStaff.Arpeggio.padding = 0.1
% A bit of padding to the left?
\once \override PianoStaff.Arpeggio.extra-spacing-width = #'(-1 . 0)
g'\arpeggio
}
\new Staff \relative {
\clef bass
<e g b>\arpeggio
}
>>
Best,
Jean
