|
| A few years ago, inspired by a fantastic scale revealed by Jacky Ligon on th nonoctave forum, I (Andrew Heathwaite) embarked on a quest to discover scales that meet these three criteria:
| | ... |
|
| |
|
| 1. [[Superparticular]] - meaning that th steps of th scale represent th intervals between adjacent notes in th harmonic series. You can identify these intervals easily, because they appear in th form //n/n-1.// Examples: 5/4, 7/6, 13/12, 122/121, etc.

|
| |
|
| 2. [[Nonoctave]] - meaning that th scale repeats at an interval other than an octave. In fact, for this project I wanted near-octaves, intervals like 1193 cents, 1221 cents, & so on. These intervals can sound very harsh, but they can also sound incredibly rich & dynamic. Timbre plays an important role here in making these near-octave intervals function as octaves.

| | Jacky Ligon's scale meets these three criteria. I will use it as an example: |
| | |
| | ''Steps: 9:8, 12:11, 9:8, 12:11, 9:8, 12:11, 12:11'' |
| | |
| | <ol><li>It is superparticular because its intervals, 9/8 & 12/11, both fit the form ''n/n-1''.</li><li>It is nonoctave (more accurately, near-octave) because it repeats at 1214.2 cents.</li><li>It is MOS because it contains exactly two step sizes, spaced out as evenly as possible within the scale.</li></ol> |
| | |
| | Inspired by the peculiar musical qualities of this scale, I set about looking for others, & found quite a few. I gave some of them quirky nicknames. I have since then embarked on a search for all scales of this type within these (admittedly arbitrary) limits: |
| | |
| | <ol><li>Superparticular Limit: smallest interval: 41/40 = 42.8 cents.</li><li>Nonoctave Limit: greatest deviation from octave allowed = 25 cents.</li><li>Moment of Symmetry Limit: greatest number of notes in a scale = 10.</li></ol> |
| | |
| | Even with these limits in place, this produces a multitude of fascinating scales for our enjoyment & fascination. I invite you to play & share your results! |

NOTE: I haven't completed the list of scales on this page. Consider that part under construction. You can check the intro & the few scales I have in the meantime, though!
...
A few years ago, inspired by a fantastic scale revealed by Jacky Ligon on the nonoctave forum, I (Andrew Heathwaite) embarked on a quest to discover new scales that meet these three criteria:
- Superparticular - meaning that the steps of the scale represent the intervals between adjacent notes in the harmonic series. You can identify these intervals easily, because they appear in the form n/n-1. Examples: 5:4, 7:6, 13:12, 41:40, etc.
- Nonoctave - meaning that the scale repeats at an interval other than an octave. In fact, for this project I wanted near-octaves, intervals like 1193 cents, 1221 cents, & so on. These intervals can sound very harsh, but they can also sound incredibly rich & dynamic. Timbre plays an important role here in making these near-octave intervals function as octaves.
- Moment of Symmetry - meaning that the scale contains exactly two step sizes, spaced out as evenly as possible within the scale. Normally, you build MOS scales by continuously adding notes a given interval, called the generator, away from one another in one long chain until the resulting scale has only two step sizes. Pythagorean scales use 3/2 (the perfect fifth) as the generator. In 12edo, we can identify the standard pentatonic scale & the various diatonic scales as MOS scales because you can build them using a chain of fifths.
Jacky Ligon's scale meets these three criteria. I will use it as an example:
Steps: 9:8, 12:11, 9:8, 12:11, 9:8, 12:11, 12:11
- It is superparticular because its intervals, 9/8 & 12/11, both fit the form n/n-1.
- It is nonoctave (more accurately, near-octave) because it repeats at 1214.2 cents.
- It is MOS because it contains exactly two step sizes, spaced out as evenly as possible within the scale.
Inspired by the peculiar musical qualities of this scale, I set about looking for others, & found quite a few. I gave some of them quirky nicknames. I have since then embarked on a search for all scales of this type within these (admittedly arbitrary) limits:
- Superparticular Limit: smallest interval: 41/40 = 42.8 cents.
- Nonoctave Limit: greatest deviation from octave allowed = 25 cents.
- Moment of Symmetry Limit: greatest number of notes in a scale = 10.
Even with these limits in place, this produces a multitude of fascinating scales for our enjoyment & fascination. I invite you to play & share your results!
