There is one notable low-harmonic-entropy scale with this [[MOSScales|MOS]] pattern: [[Porcupine_family|Porcupine]], in which two generators make a 6/5 and three make a 4/3.
{{Infobox MOS}}
{{MOS intro}}
== Name ==
{{TAMNAMS name}} The name derives from several naming puns/reasonings:


Other scales include very improper (incomplete) versions of negri, 12edo, etc.
* The name sounds like its step counts of '''one''' large step and '''six''' small steps.
* Onyxes come in different colors and types, which is a metaphor for this scale's generator range being quite large and containing the generator ranges of other MOS scales, such as [[7L 1s]], [[8L 1s]], and [[9L 1s]].
* Building on the observation that it is the 7-note (heptatonic) MOS that is the ancestor of all xL 1s scales with x>6, the name "onyx" also sounds similar to "one x", as in 1 large step and x small steps.
* The name "onyx" is also supposed to be vaguely reminiscent of "anti-archaeotonic" as "chi" (the greek letter) is written like an "x" (this is related to why "christmas" is abbreviated sometimes as "X-mas") and the letters "o" and "n" and their sounds are also present in "archaeotonic", and "x" is vaguely reminiscent of negation and multiplication. There is also something like a "y" sound in "archaeotonic" in the "aeo" part.

There is one notable harmonic entropy minimum: [[porcupine]], in which the generator is between 150 and 170{{c}}, two generators make a [[6/5]] (315.6{{c}}), and three make a [[4/3]] (498{{c}}).
