	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. Ledger lines follow the same pattern as the staff lines. Though such notation does not have to be microtonal, some quarter-tones have been added to show that they still work. Improvements are welcome.		This twelve-note staff demonstrates a contemporary notation described by Erv Wilson.

% LSR originally contributed by Graham Breed for version 2.11.65
% Correct ledger line pattern added by Paul Morris (at version 2.18.2)

% Dodecaphonic notation, after Erv Wilson, but probably an earlier idea.

% keep the original pitch names.
