'''4ado''' is the [[ADO|arithmetic equal division of the octave]] into four parts of 1/4 each. 4ado is perhaps the smallest ADO that contains useful intervals for harmony, containing the major third, perfect fifth, and harmonic seventh. | '''4ado''' is the [[ADO|arithmetic equal division of the octave]] into four parts of 1/4 each. 4ado is perhaps the smallest ADO that contains useful intervals for harmony, containing the major third, perfect fifth, and harmonic seventh. Because 4 is a power of 2, 4ado corresponds to the 1st to 4th harmonics octave-reduced. | ||
