Move the discussion about temps to the right section. This covers the lesser tendoneutralisma and the tridecimal neutral thirds comma so they don't need to appear again in the "see also" section. |

The '''greater tendoneutralisma''' is a [[small comma]] of the 2.3.13 [[subgroup]] which is the amount by which a stack of eight [[16/13]]'s minus two [[octave]]s falls short of [[4/3]]; that is, it is equal to ([[16/3]])/([[16/13]])<sup>8</sup> and so equivalently also to ([[13/3]])/([[16/13]])<sup>7</sup>. | The '''greater tendoneutralisma''' is a [[small comma]] of the 2.3.13 [[subgroup]] which is the amount by which a stack of eight [[16/13]]'s minus two [[octave]]s falls short of [[4/3]]; that is, it is equal to ([[16/3]])/([[16/13]])<sup>8</sup> and so equivalently also to ([[13/3]])/([[16/13]])<sup>7</sup>. | ||

Although the comma is similar in size to something like 81/80, the corresponding temperament is quite accurate because the error can be split evenly over eight 16/13's, so that the pure-3's tuning (very close to [[53edo]]) has 13 off by only 2.78{{cent}}. A more accurate (lower damage) way of achieving the same (finding 3 by stacking 13's) is by tempering the [[lesser tendoneutralisma]]. Very importantly, both are distinct ways of mapping 2.3.13, so that you cannot combine them unless you want to use the trivial tuning of [[10edo]], so that edos > 10 which have a good 3 and 13 will usually pick between one of these two mappings. A much simpler but relatively much higher error way of mapping 3 for those that prefer sharp fifths is by tempering ([[16/13]])<sup>2</sup>/([[3/2]]) = [[512/507]]. | |||

Tempering out the greater tendoneutralisma in 2.3.13 leads to the highly notable 10 & 53 temperament, where [[10edo]] is the trivial tuning approximately equal to the pure-13's tuning and [[53edo]] is the tuning practically equal to the pure-3's tuning, although [[43edo]] is an interesting choice for combining this temperament with meantone and [[63edo]] is an interesting choice if you prefer slightly sharp fifths. This temperament is related to [[submajor (temperament)|submajor]], which extends it to the full [[13-limit]]. | Tempering out the greater tendoneutralisma in 2.3.13 leads to the highly notable 10 & 53 temperament, where [[10edo]] is the trivial tuning approximately equal to the pure-13's tuning and [[53edo]] is the tuning practically equal to the pure-3's tuning, although [[43edo]] is an interesting choice for combining this temperament with meantone and [[63edo]] is an interesting choice if you prefer slightly sharp fifths.
