'''8ado''' is the [[ADO|arithmetic equal division of the octave]] into eight parts of 1/8 each. Because 8 is a power of 2, 8ado corresponds to the 1st to 8th 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]].
 
{{Harmonics intro|8}} 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 [[otonal heptad]] can be obtained by removing harmonic 15.
 
The smallest [[edo]] that maintains 25% or lower relative error on all intervals of this scale is [[87edo]].
