4ado is the 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.
