Corollaries are things that anyone could say: there is a quality of self-evidence to them.
Corollaries are obvious to some, not-so-obvious to others. They are useful to have a grip on.
Equal temperaments are equal on the logarithmic scale, and harmonic series are equal on the frequency scale. The logarithmic scale is the logarithm of the frequency scale. (Could a logarithm of the logarithm scale be useful? Or an exponential of the frequency scale? Or a power of any one of these?)
Prime edos make every interval repeated cycle through the whole thing. --William Lynch.
Dyads are distributionally even by definition, but "real" triads must not be distributionally even; and distributionally even interlaced tetrads and hexatonic scales cannot exist in equal divisions of a cardinality relatively prime to 4 or 6.
A tenth splits the difference between the octave and the twelfth,
