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.
