'''18afdo''' ([[AFDO|arithmetic frequency division of the octave]]), or '''18odo''' ([[otonal division]] of the octave), divides the octave into 18 parts of 1/18 each. As a scale it may be known as [[Harmonic mode|mode 18 of the harmonic series]] or the [[Overtone scale #Over-n scales|Over-18]] scale. | '''18afdo''' ([[AFDO|arithmetic frequency division of the octave]]), or '''18odo''' ([[otonal division]] of the octave), divides the octave into 18 parts of 1/18 each.
