-'''21afdo''' ([[AFDO|arithmetic frequency division of the octave]]), or '''21odo''' ([[otonal division]] of the octave), divides the octave into 21 parts of 1/21 each. It is a superset of [[20afdo]] and a subset of [[22afdo]]. As a scale it may be known as [[Harmonic mode|mode 21 of the harmonic series]] or the [[Overtone scale #Over-n scales|Over-21]] scale.
