UNDERTONE --------- OVERTONE

The Pythagorean table (Lambdoma diagram) is depicted in its actual proportions of division (horizontally) and multiplication (vertically) the beginning tone 1/1 is D.
The shape of the subsequent multiples of the beginning which normally fall along the diagonal in diamond shapes change from a rectangle to a square to a vertical rectangle 3/3 to ever lengthening vertical rectangles which eventually become longer and longer lines.
The circular lines become as peeled off layers of the undertone vertical bands. If the grid were set up on the curvilinear format it would take the shape of the upper right portion, the beginning tone in this case initiating the sequence at F. The coordinate axes X and Y curve as opposed to the coordinated axes of X1 and Y1 .
