User:Aura/On 159edo Music Theory (Part 1)

Of all the multiples of 53edo, 159edo is the lowest multiple that is noteworthy for being accurate in the 2.3.5.11.17 subgroup while having structural compromises in the 7.13.19.23.29 subgroup. Despite the number of pitches in this tuning system making it perhaps best fit for digital instruments of various kinds in actual performance, it is nevertheless also useful as an interval classification scheme.

Intervals and Notation

159edo contains all the intervals of 53edo and can be thought of as having three fields of 53edo each separated by a third of 53edo's step. However, as some of the interpretations differ due 159edo having different mappings for certain primes, those differences show up in how harmonies are constructed.

159edo has its own variation on the dinner party rules— represented here by the Harmonic Compatibility Rating and Melodic Compatibility Rating columns in the following chart, where 10 is a full-blown friend relative to the root and −10 if a full-blown enemy relative to the root. Note that the Harmonic Compatibility and Melodic Compatibility ratings are based on octave-equivalence, and that some of the ratings are still speculative.
