-'''4ado''' is the [[ADO|arithmetic equal division of the octave]] into four parts of 1/4 each. 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.
+'''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.
