Template:Infobox ADO 12ado (arithmetic division of the octave), or 12odo (otonal division of the octave), divides the octave into twelve parts of 1/12 each. As a scale it may be known as mode 12 of the harmonic series or the Over-12 scale. 12ado is a subset of the esoteric Factor 9 grid temperament connected to "A = 432 Hz" conspiracy.
