As another step toward in my path toward varying notation in LilyPond,
I am varying note shapes by semitone. Usually, there are fewer than
12 note heads, but the semitone of the note determine the shape.
My current implementation uses a function shapeLayoutFunction which
returns an integer, which is an index into the vector
shapeNoteStyles. This seems to work. The function description is:
Function returning an integer which indexes into
shapeNoteStyles vector. It takes an argument of
pitch and tonic.
Altnernatively, I could define a function which return a note head
shape. Does anyone see a good reason to prefer one to the other.
The first option has an advantage of using a small function like this:
#(define (shapeSemitone pitch tonic)
(modulo (ly:pitch-semitones pitch) 12))
plus an already standard vector.
The second option has an advantage of everything being included in one
variable, but the disadvantage of requiring slightly more complicated
functions.
