As shown on the right, Carcelle’s notation has been designed to be
read vertically from top to bottom like Klavar notation. Pitches ascend
horizontally from left to right like on a piano keyboard. The standard staff
spans about an octave and a half. It has a symmetrical set of nine lines
combining solid, dotted, and dashed lines. The last three repeat the first
three in the following pattern: solid, dotted, solid, solid, dashed, solid,
solid, dotted, solid. Traditional noteheads and time values are used.
