< Keemun

Keemun has various competing extensions to the 11- and 13-limit. The following temperaments are discussed in this article:

  • Tridecimal keemun (15 & 19) – tempering out 49/48, 56/55, 91/90, 100/99;
  • Kimah (15f & 19) – tempering out 49/48, 56/55, 65/64, 100/99;
  • Kumbaya (15 & 19f) – tempering out 40/39, 49/48, 56/55, 66/65;
  • Qeema (15e & 19) – tempering out 45/44, 49/48, 78/77, 126/125;
  • Darjeeling (15 & 19e) – tempering out 49/48, 55/54, 66/65, 77/75.

See Kleismic family #Keemun, #Kimah, #Kumbaya, #Qeema, and #Darjeeling for technical data.
