This page presents a novelty topic.

It may contain ideas which are less likely to find practical applications in music, or numbers or structures that are arbitrary or exceedingly small, large, or complex.

Novelty topics are often developed by a single person or a small group. As such, this page may also contain idiosyncratic terms, notation, or conceptual frameworks.

Theory

This EDO has a consistency limit of 21, which is the most impressive out of all the 3-2 telic multiples of 190537edo. It tempers out the Archangelic comma in the 3-limit, and though this system's 5-limit and 7-limit are rather lackluster for an EDO this size, the representation of the 11-prime is a bit better, and the representations of the 13-prime, 17-prime, and 19-prime are excellent, all which help to bridge the lackluster 5-prime and 7-prime. Thus, this system is worthy of a great deal of further exploration in the 19-limit.

In this system, the perfect fifth at 2452054\4191814 is divisible by the prime factors of 2, 11, 227 and 491. However, the perfect fourth, at 1739760\4191814, has more prime divisors, namely the prime factors of 2^4, 3, 5, 11 and 659. The latter means that just as in 159edo, the perfect fourth is divisible by 33, and thus, this system can offer not only a more accurate version of Ozan Yarman's original 79-tone system, but also metatemperaments to Yarman I and Yarman II.
