159edo interval names and harmonies

159edo contains all the intervals of 53edo, however, as some of the interpretations differ due 159edo having different mappings for certain primes, those differences show up in how harmonies are constructed. It should be noted that since 159edo does a better job of representing the 2.3.11 subgroup than 24edo, some of the chords listed on the page for 24edo interval names and harmonies carry over to this page, even though the exact sets of enharmonics differ between the two systems. Furthermore, just as with 24edo can be thought of as essentially having two fields of 12edo separated by a quartertone, 159edo can be thought of as having three fields of 53edo, each separated from the others by a third of a 53edo step on either side. This even lends to 159edo having its own variation on the Dinner Party Rules- represented here by the Harmonic Compatibility Rating and Melodic Compatibility Rating columns where 5 is a full-blown friend relative to the root and -5 if a full-blown enemy relative to the root. Note that the Harmonic Compatibility and Melodic Compatibility ratings are based on octave-equivalence, and many of the ratings are speculative at this point, adjustments are to be expected in the future.

Harmonies

Harmonies in 159edo frequently have to follow a variation on the Dinner Party Rules. However, working with these rules in a system like this requires a more detailed list of "friends" and "enemies". Thus, what will be listed here are a series of basic trines, triads and tetrads.

First, the trines, of which there are already a noticeable abundance.

Next, the basic triads, which end up inheriting the base trine's type, and as a consequence, there are even more triads than there are trines, though this list will only cover the triads that build off of the Otonal Perfect Trine for the sake of ease. Of course, it should be mentioned that suspensions occur where there's overlap between thirds and fourths, and these are excluded from this list along with augmented and diminished triads and variations thereof.
