''' | '''7afdo''' ([[AFDO|arithmetic frequency division of the octave]]), or '''7odo''' ([[otonal division]] of the octave), divides the octave into seven parts of 1/7 each. It is a superset of [[6afdo]] and a subset of [[8afdo]]. As a scale it may be known as [[Harmonic mode|mode 7 of the harmonic series]] or the [[Overtone scale#Over-7 scales|Over-7]] scale. As 7 is a small odd number, 7afdo does not contain a perfect fifth or any reasonable approximation to one in its root position. This makes 7afdo relatively poor for its size at creating traditional tonal music unless rotated. | ||
