''' | '''11afdo''' ([[AFDO|arithmetic frequency division of the octave]]), or '''11odo''' ([[otonal division]] of the octave), divides the octave into eleven parts of 1/11 each. It is a superset of [[10afdo]] and a subset of [[12afdo]]. As a scale it may be known as [[Harmonic mode|mode 11 of the harmonic series]] or the [[Overtone scale #Over-n scales|Over-11]] scale. As 11 is a small odd number, this AFDO does not contain a perfect fifth above the root, although it does contain a [[16/11]] subfifth and a [[17/11]] ultrafifth / inframinor sixth. | ||
