-'''4ado''' ([[ADO|arithmetic division of the octave]]), or '''4-ODO''' ([[otonal division]] of the octave), divides the octave into four parts of 1/4 each. As a scale it may be known as [[Harmonic mode|mode 4 of the harmonic series]] or the [[Overtone_scale#Over-n_scales|Over-4]] scale. Because 4 is a power of 2, 4ado corresponds to the 4th to 8th harmonics octave-reduced. The notes of 4ado create a harmonic seventh chord.
+{{Harmonics intro|4}} The notes of this scale create a [[4:5:6:7|harmonic seventh chord]].
+The smallest [[edo]]s that maintain 25% or lower relative error on all intervals of this scale are [[10edo]] and [[15edo]], though they are not very accurate. The next two edos, [[22edo]] and [[31edo]], are the smallest that approximate this scale with appreciable accuracy.
