This staff is basically identical to Isomorph Notation by Tadeusz Wójcik and it uses the same alternating notehead color. The pitches are different with the heavy bottom and top lines representing C. Also, the rhythmic notation is mostly traditional rather than proportional. Rich Reed’s design was his modification of Wojcik’s design.
