Thus as the triplets form from the swirling and concentrating etheric (atomolic) substance (i.e., Mind) they are naturally polarized in relation to each other. Three will naturally aggregate to form into a larger triplet - the natural result of the three polar states' mutual seeking and repulsion. This triple assemblage can take only six forms. This triple aggregation will multiply in size by threes eventually forming large molecules of the same configuration. Figure 7B.05 - Triplet Forming a Unity shows in black how the contracting zones (equators) seal over each other maintaining the whole as a unit of compound and complex motions.
"By affinity the notes group in chords. The tonic is the center chord, the key of harmony; the dominant is the fifth above it and the subdominant the fifth below it, and these two are balanced on the center chord as the scales on a balance beam. The dominant chord is vigorous and active, tending to soar; the subdominant is solemn, soft, and grave, tending to sink; the tonic is melodious and restful, and in it the harmony of equilibrium. This far AFFINITY." [Scientific Basis and Build of Music, page 91]
