65/64: Difference between revisions

In [[Just_intonation|Just Intonation]], 65/64, the wilsorma, is a [[superparticular|superparticular]] interval of around 26.8¢, nearly a quarter of a semitone or eighth of a tone. It belongs to the 13-prime limit, which means that the highest prime in the ratio is 13. 65 is 5 times 13, which means that 65/64 can be treated as a harmonic 13th above a harmonic 5th or vice versa. It is the difference between [[5/4|5/4]] and [[16/13|16/13]]; [[8/5|8/5]] and [[13/8|13/8]]; [[13/12|13/12]] and [[16/15|16/15]]; [[15/8|15/8]] and [[24/13|24/13]], [[13/10|13/10]] and [[32/25|32/25]]; [[20/13|20/13]] and [[25/16|25/16]], and of course, infinitely many other pairs of just intervals.
