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

From Xenharmonic Reference

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. However, there's more.

Of all the intervals in 159edo, 5\159 is the first interval to be larger than the fission boundary, which is where going back and forth between notes on either end of a given interval no longer sounds like a simple vibrato, but more like a dirty trill of sorts. The fission boundary further serves as the line separating melodic notes that can only be simple ornaments or quick passing tones from main melodic intervals, and since 5\159 is larger than this boundary it is the smallest interval that can serve as a main melodic interval.

The next landmark interval is 8\159, as this is the first interval to be larger than the gradient threshold, which is where going back and forth between notes on either end of a given interval no longer sounds like a dirty trill, but rather a clean trill. The gradient threshold doubles as the point beyond which microtonal intervals can begin to serve as proper leading-tones.

Finally, 33\159 is the first interval to be larger than the trill threshold, which is where going back and forth between notes on either end of a given interval no longer sounds like any kind of trill, and instead sounds like an arpeggio fragment. The trill threshold doubles as the boundary between intervals that are classified as steps, and those that are classified as leaps. As a consequence of this, the trill threshold marks the boundary where intervals cease to cause crowding in chords.

As if all that weren't enough, 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.

Trines

159edo has multiple types of trine. Trines are important in the aspects of 159edo music theory derived from Medieval and Neo-Medieval music theory- specifically they're the result of two notes forming an octave, along with a third note for stark contrast, being played simultaneously, which is how 3-limit harmony naturally works. That said, there are such things as dissonant trines, in which the third note is something other than a perfect fourth or perfect fifth away from the doubled root- in fact the third note can be anything from a paraminor fourth to a paramajor fifth relative to the root.

The individual intervals that constitute trines serve as the backbone of not only the triads of harmony, but the tetrachords of melody as well. Both triads and tetrachords will be covered in later installments of this series. For now, it pays to go over which three-note structures can serve as trines as well as their names.

Table of 159edo Trines
