Original Wikitext content:
The head of the marvel family is marvel, which tempers out 225/224, the septimal kleisma or marvel comma. Marvel has a [[Normal lists|normal list basis]] of [2, 3, 5]; hence a [[Harmonic Limit|5-limit]] scale can be converted to marvel simply by tempering it. One way to do that, and an excellent marvel tuning, is given by [[197edo]]. Little is gained in tuning accuracy by not tempering out 4375/4374 as well as 225/224, leading to [[Kleismic family|catakleismic temperament]]. Another temperament which does little damage to tuning accuracy is [[Pythagorean family|compton temperament]], for which [[240edo]] may be used. ===Vital statistics=== [[Comma]] c = 225/224 7-limit minmax: 3 and 5 1/4c flat, 7 just [|1 0 0 0>, |5/4 1/2 -1/2 1/4>, |5/4 -1/2 1/2 1/4>, |0 0 0 1>] [[Eigenmonzo|Eigenmonzos]]: 2, 5/4, 6/5 9-limit minimx: 3 1/6c flat, 5 1/3c flat, 7 just [|1 0 0 0>, |5/6 2/3 -1/3 1/6>, |5/3 -2/3 1/3 1/3>, |0 0 0 1>] [[Eigenmonzo|Eigenmonzos]]: 2, 8/7, 10/9 [[Minkowski lattice]] basis: secor length 1.256, 3/2 length 1.369 Angle(secor, 3/2) = 106.958 cents Map to lattice: [<0 0 -1 -2|, <0 1 -1 0|] [[edo|EDOs]]: [[197edo|197]] ==Eleven limit children== The second comma of the [[Normal lists|normal comma list]] defines which 11-limit family member we are looking at.
