'''2EDT''', if the attempt is made to use it as an actual scale, would divide the [[3/1|tritave]] into two equal parts, each of size 950.9775 cents, which is to say sqrt(3) as a frequency ratio. If we want to consider it to be a temperament, it tempers out [[27/25]], equating 5/3 with 9/5.

==Factoids about 2EDT==
=== Theory ===
[[26/15]] and 45/26 are [[Nearest just interval|good rational representations]] of the square root of 3.


2EDT is closely related to the [[Very high accuracy temperaments|monzismic temperament]], which tempers out |54 -37 2>, the monzisma.
As a temperament in the 3.5 [[subgroup]], it tempers out [[27/25]], equating 5/3 with 9/5.
 
Since [[26/15]] is a convergent of sqrt(3), 26/15 (and its [[tritave complement]] 45/26) are good rational representations of the square root of 3. 2edt thus tempers out (26/15)<sup>2</sup> / (3/1) = [[676/675]], the island comma.
 
One step of 2edt is close to the optimal TE generator of [[Very high accuracy temperaments|monzismic temperament]], which tempers out {{monzo|54 -37 2}}, the monzisma.
