'''~~8ado~~''' ([[~~ADO~~|arithmetic division of the octave]]), or '''~~8-ODO~~''' ([[otonal division]] of the octave), divides the octave into eight parts of 1/8 each. As a scale it may be known as [[Harmonic mode|mode 8 of the harmonic series]] or the [[~~Overtone_scale~~#Over-~~n_scales~~|Over-8]] scale. Because 8 is a power of 2, ~~8ado~~ corresponds to the 8th to 16th harmonics octave-reduced. ~~8ado~~ is a highly effective scale ~~and~~ contains many commonly-used intervals such as [[9/8]], [[5/4]], [[3/2]], [[7/4]], [[15/8]], and [[2/1]].

'''8afdo''' ([[AFDO|arithmetic frequency division of the octave]]), or '''8odo''' ([[otonal division]] of the octave), divides the octave into eight parts of 1/8 each. It is a superset of [[7afdo]] and a subset of [[9afdo]]. As a scale it may be known as [[Harmonic mode|mode 8 of the harmonic series]] or the [[Overtone scale #Over-n scales|Over-8]] scale. [[Dante Rosati]] calls this the "Diatonic harmonic series scale". Because 8 is a power of 2, 8afdo corresponds to the 8th to 16th harmonics octave-reduced. 8afdo is a highly effective scale. Above its root it contains many commonly-used intervals such as [[9/8]], [[5/4]], [[3/2]], [[7/4]], [[15/8]], and [[2/1]].

The smallest [[edo]] that maintains 25% or lower relative error on all intervals of 8afdo is [[87edo]].
