'''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]]. | '''8ado''' is the [[ADO|arithmetic equal division of the octave]] into eight parts of 1/8 each.

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 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 and the 4:5:6 major triad.
