Amity (from "acute minor third"), ​46 & ​53, is a complex 7-limit temperament splitting 8/3 into 5 supraminor thirds about 339c-340c in size. It has a tuning that is very accurate in the 7-limit (namely 99edo).

Amity is a 7-cluster temperament due to its generator being only slightly flatter than 2\7.

Interval chain

Notes:

  • 243/200 is 6/5 sharpened by 81/80.
  • The extension to 13 given is called Hitchcock, whose 13 mapping tends to be flat due to tempering out S13.
