The way pitch is written in Dodeka alternative music notation is quite different from conventional music notation. For one thing, musical notes are now written on a staff of only four lines (instead of five in conventional notation).
Also in Dodeka notation, we use twelve notes, instead of seven, or what is often called as the chromatic scale by opposition to the diatonic scale. There is no longer any flat or sharp symbols in this notation.
In addition, the notes are themselves represented through small black rectangles. These rectangles either appear on, above, below, or between the structure of four lines. This way, we identify musical pitch, - the degree of highness or lowness of a sound - based on where the notes are placed on this four-line structure. By placing all twelve notes within four lines, all notes keep their position on the staff regardless of the octave.
