MODULES ILLUSTRATING RATIOS. 1:2, 2:3, 3:4 ETC.

On a Lambdoma grid of 16 fractions 1/1 to 16/16 one might portray the ratios as lengths differing by one unit placed one on top of the other. The areas marked "space" show the areas on which no ratios considered musical lie.
To the left the same pattern of locations are designated by small spheres on either side of the diagonal. Also on the right the four bar depressions indicate a negative space. The tone A 3:5 is seen to fall in this space area.
The dotted wavy line shows the tones used in the Lambdoma grid as a 60° section of a circle.
