2835/2816: Difference between revisions

Re-organize, giving each topic a distinct section. Make "fwiwisma" official cuz it's used to name 44/35. Recategorize accordingly.

'''2835/2816''', the '''fwiwisma''', is a [[comma]] with a value of approximately 11.6 [[cent]]s. It represents the difference between [[45/44]] and [[64/63]]. It is also the difference between the Pythagorean major third ([[81/64]]) and [[44/35]].
'''2835/2816''', the '''fwiwisma''', is a [[comma]] with a value of approximately 11.6 [[cent]]s. It represents the difference between:
* [[45/44]] and [[64/63]]
* [[81/64]] and [[44/35]].
* [[729/512]] and [[99/70]]
 
Due to this last difference, it notably serves as a half [[pythagorean comma]] for a strong rational representation of √2-[[hemipyth]].
 
It factors into simpler commas as ([[243/242]])⋅([[385/384]]) or ([[225/224]])⋅([[441/440]]).

This comma is [[tempering out|tempered out]] in [[miracle]], as well as supporting edos {{EDOs| 31, 41, and 72 }}. It is also the sum of [[243/242]] and [[385/384]], and so is tempered out in the rank-3 temperament [[mirwomo]].  
[[Tempering out]] this comma results in the rank-4 '''fwiwismic''' temperament. Since this comma is the sum of 243/242 and 385/384, it is tempered out in the rank-3 temperament [[mirwomo]], and since it is the sum of 225/224 and 441/440, it is tempered out in the rank-3 temperament [[prodigy]]. As such, it is tempered out in [[miracle]], as well as [[support]]ing edos {{EDOs| 31, 41, and 72 }}.  
 
If instead tempered, in [[kalismic]], the pythagorean comma is halved, wherein each half represents 2835/2816~[[72171/71680]].
