65/63 is a 13-limit quartertone measuring about 54.1 cents. It is known as the radius of tolerance in the Functional Just System[1].
It arises as the sum of 64/63 and 65/64, the difference between 7/5 (septimal narrow tritone) and 13/9 (tridecimal high tritone), between 5/3 and 21/13, between 10/9 and 14/13, and between 13/12 and 21/20.
It differs from the 33/32 semitone by 2080/2079 – an unnoticeable comma measuring about 0.83 cents.
