To the wizma [-6 -8 2 5⟩ = 420175/419904, the kalisma is a natural complement, as their product is the [[tinge]]. | |||
18/7 is a possible [[equave]]. [[Fokker block]]s of 128 notes are available for it, corresponding to 94edo. 18/7 is split into 4 parts that become ~19/15 in 19-limit. Also, (18/7)<sup>3</sup> ~ 17/1 via the [[5832/5831|chlorisma]]. However, the tones 9/8 and (19/15)/(9/8) = 152/135 have distinct mappings. | |||

The square root of the latter is close to 35/11. This suggests tempering out (81/8)(35/11)<sup>-2</sup>, which is the kalisma. | ||

When 3/2 is chosen as the equave, [[Fokker block]]s of 34 pitches per equave can be used that are close to [[34edf]] and [[58edo]]. | ||
