Hemifamity or Aberschismic, 2.3.5.7[41 & 46 & 53], is a 7-limit rank-3 temperament that tempers out 5120/5103 (known as the hemifamiton or the aberschisma), which manifests in several different ways:

  1. equates the 3-spine prime commas for 5 and 7, 81/80 and 64/63
  2. equates the limma 256/243 with 21/20
  3. equates the apotome 2187/2048 with 15/14
  4. equates the Pythagorean augmented fourth 729/512 with 10/7
  5. splits 36/35 into two equal parts each representing the "comma" 81/80 ~ 64/63

Supporting rank-2 temperaments

Extensions

  • Prime 11 may be added by tempering out either 385/384 (thus equating 36/35 with 33/32; this is called Akea) or 896/891 (thus equating 81/64 with 14/11; this is called Pele).
  • Prime 13 may be added by tempering out 4096/4095; this is the most efficient extension that adds prime 13 and is supported by edos as big as 140edo.
