⌂ Dodecaphonic staff

This twelve-note staff demonstrates a contemporary notation described by Erv Wilson. It works similarly to a piano keyboard: black notes are on the lines and white notes are in the spaces. Though such notation does not have to be microtonal, some quarter-tones have been added to show that they still work. Ledger lines do not follow the same pattern as the staff lines. Here they have been made as thin as possible for now; a better hack would be to draw them a bit higher, so that they're above the note head for C. (And draw them a bit lower below the staff so that the first one's under B.) Improvements are welcome.
