16afdo
16afdo (arithmetic frequency division of the octave), or 16-ODO (otonal division of the octave), divides the octave into 16 parts of 1/16 each. It is a superset of 15afdo and a subset of 17afdo. As a scale it may be known as mode 16 of the harmonic series or the Over-16 scale. Because 16 is a power of 2, 16afdo corresponds to the 16th to 32nd harmonics octave-reduced.
The smallest edo that maintains 25% or lower relative error on all intervals of 16afdo is 311edo.
