Diaschismic–gothmic equivalence continuum

The diaschismic-kleismic equivalence continuum is a continuum of 5-limit temperaments which equate a number of kleismas (15625/15552) with the Würschmidt_comma (393216/390625).

All temperaments in the continuum satisfy (15625/15552)n ~ 393216/390625. Equivalently, we can offset n by 1, and equate a number of kleismas with the diaschisma (2048/2025), hence the name. Varying n results in different temperaments listed in the table below. It converges to hanson as n approaches infinity. If we allow non-integer and infinite n, the continuum describes the set of all 5-limit temperaments supported by 34edo due to it being the unique equal temperament that tempers both commas and thus tempers all combinations of them. The just value of n is 1.4117…, and temperaments near this tend to be the most accurate ones.

An equally reasonable way of defining this continuum equates a number of diaschismas with the Würschmidt comma, so that (2048/2025)m ~ 393216/390625. The value of m is defined such that 1/m - 1/n = 1, and its just value is 0.5853…. The gothic comma (134217728/129140163) is the characteristic 3-limit comma tempered out in 34edo, and it has a value of m = 4. Therefore, one can additionally define k = 4 - m, which has notable advantages - in particular, due to being determined in terms of the 3-limit comma and the comma with the next lowest power of 5, the value of k represents the number of generator steps required to reach the 3rd harmonic, even as n comes naturally from examining a chain of commas connected by kleismas.

We may invert the continuum by setting m such that 1/m - 1/n = 1. This may be called the wurschmidt-diaschismic equivalence continuum, or the diaschismic-gothic equivalence continuum, which is more or less the same thing.
