"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]
