Re: The ditone is truly not a third

The ditone (or the 81/64 or 408 cents) interval is not a "third" in any
functional sense. It is not a holistic part of a harmony, but rather the sum
of 2 whole tones (of 9/8 or 204 cents). And it was never called a third
during its use in Europe.

Playing the musicology game of "psychological differences regarding thirds
through history" is to help disguise ignorance. This is an important
distinction because there are many different sizes of tempered thirds.
However, the ditone is not even a tempered interval.
