Template:Infobox ADO 8ado is the arithmetic equal division of the octave into eight parts of 1/8 each. 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.
