This comma is tempered out in [[buzzard]] systems such as [[53edo]] and [[58edo]]. | This comma is tempered out in [[buzzard]] systems such as [[53edo]] and [[58edo]]. In fact, it is the comma singled out by restricting buzzard to the 2.3.7 subgroup. Tempering it out alone in the full 7-limit leads to the rank-3 '''buzzardsmic temperament''' instead. In either case, the perfect twelfth is split into four equal parts, each for 21/16. In addition, the [[256/243|Pythagorean limma (256/243)]] is also split into four, one for [[64/63]], two for [[49/48]], and three for [[28/27]]. | ||
