Only...I can't figure out how to make it move up or down. If someone could
help me with this I'd really appreciate it.
This adds another argument to the function which will move the markup up or down:
\version "2.15.16"
dwn =
#(define-music-function (parser location note offset) (ly:music? number?)
#{ \once \override Voice.Accidental #'stencil =
#ly:text-interface::print
\once \override Staff.AccidentalPlacement #'right-padding = #2
\once \override Voice.Accidental #'text =
\markup {
\halign #-1 \translate #(cons 0 $offset) \musicglyph #"custodes.mensural.u0"
}
$note #})
\dwn g! #1
Hope this helps--
David
