Hi Freeman,
Now that you have mentioned microtonality more clearly--I admit I was
confused by your original request, thinking only that you wanted to
change the look of an existing accidental--would the following
information be of any use to you?
http://x31eq.com/lilypond/
In particular, the section on accidentals mentions that you can define
your own alist of symbols that correspond to fractions of wholetones.
You should be able to use `ly:make-pitch` to define the microtones as
you need them. It should even be possible to follow the example in
`define-note-names.scm` to define your own language so you can more
easily specify the accidentals. Then you could theoretically use these
new notes in a normal fashion:
%%%%
\version "2.19.81"
\layout {
\context {
\Score
\override Accidental #'glyph-name-alist =
#'((2/3 . "accidentals.natural.arrowup")
(-3/5 . "accidentals.mirroredflat.backslash"))
}
}
#(set! language-pitch-names
`((custom . (
(xu . ,(ly:make-pitch 0 3 2/3))
(xd . ,(ly:make-pitch 0 3 -3/5))
(yu . ,(ly:make-pitch 0 5 2/3))
(yd . ,(ly:make-pitch 0 5 -3/5))
(zu . ,(ly:make-pitch 0 7 2/3))
(zd . ,(ly:make-pitch 0 7 -3/5))
))))
\language "custom"
{ xu4 xd8( zu yd) zd~ zd2 }
%%%%
You would of course still need to add your custom glyphs for accidentals
in the font. In the example above, I just borrowed two of the
accidentals and mapped them to the two-thirds up and three-fifths down
pitches. But ultimately that is where the binding between pitch and
glyph happen.
