An improved musical notation system, which uses a staff patterned upon the standard piano keyboard. It replaces the Grand Staff's system of lines and spaces with a system of "pitch stripes" of two colors arranged in the same pattern as the black and white keys of the standard piano keyboard. Music scores, especially those for keyboard music, produced with the art are significantly easier to understand and sight-read. The art further incorporates positional numerical music notes to marry positional notation and numerical notation of music in the same musical score. The art further facilitates a method by which music scores of the same music in different keys can be obtained easily by moving all markings and notes collectively up or down the staff.
