The sqrtphi is a temperament for the 7, 11, 13, 17, and 19 prime limits. It is a member of kleismic family, mirkwai clan and wizmic temperaments. The name "sqrtphi" stands for "square root of phi", which means the positive square root of the golden ratio [math]\displaystyle{ (\sqrt{\varphi} = \sqrt{\frac{1+\sqrt{5}}{2}}) }[/math] as a frequency ratio.
See Kleismic family for more technical data.
