65edo tunes [[primes]] 2, 3, 5 and 11 very well, but its 7 and 13 have two about equally-bad mappings. [[Octave shrinking|Shrinking]] the octave of 65edo by the right amount improves its approximations of [[JI]] by flipping 7 and 13 to their opposite [[mapping]], at the cost of relatively little damage to other primes. (Stretching would do unacceptably much damage.) | |||
Some tunings of 65edo which do this include [[zpi|334zpi]], [[ed5|151ed5]] and [[equal tuning|225ed11]]. | |||
