==Theory== | '''14afdo''' ([[AFDO|arithmetic frequency division of the octave]]), or '''14odo''' ([[otonal division]] of the octave), divides the octave into 14 parts of 1/14 each. As a scale it may be known as [[Harmonic mode|mode 14 of the harmonic series]] or the [[Overtone scale #Over-n scales|Over-14]] scale. | ||

The esoteric [[Factor 9 grid]] scale is a mode of 14afdo starting on the 11th step from the tonic, of which 12 or 13 notes were conveniently selected for "A = 432 Hz" conspiracy purposes. 14afdo cocntains supraminor and supermajor triads above the root. | |||
