* In order to distinguish between the fixed category of [[:Category:Haplotonic scales]], etc., and the reciprocal relationship (haplotonic) + (albitonic) = (chromatic), the latter will be called, for example, MOS triplet. Every 3 successive generations of MOS that satisfies the above relationship will be called a MOS triplet. | |||
** Or moshaplotonic as a parent MOS, moschromatic as a descendant MOS, like that [[moschroma]] and [[mosdiesis]] are relative from any MOS scale of interest. | |||
* If the number of notes in the scale is important, consider using the [[Pentatonic]] and [[Heptatonic]] pages. | |||
* Based on the above equation and the nature of MOS, the chromatic must be a direct descendant of the albitonic. So I don't like the existence of mega-albitonic between albitonic and chromatic, even though the meanings of relational and categorical usages don't have to be exactly the same. (I will also withdraw the mini-albitonic that I said.) | |||
* Categorical haplotonic scales include the last MOS that s ≥ 125 ¢ and some subset of such scales. in <nowiki>[[Chromatic pairs]]</nowiki>, such subsets all may be labelled mini-haplotonic (even if there are more than one). | |||
* Categorical albitonic scale is the first MOS that s < 125 ¢. | |||
** If the interval that appears is too narrow to be a semitone, it may be a [[Cluster MOS]]. | |||
* Categorical chromatic scales include direct descendant of albitonic (by adding corresponding haplotonic) and further descendant <del>(by adding same haplotonic)</del>. in <nowiki>[[Chromatic pairs]]</nowiki>, such further descendants all may be labelled mega-chromatic (even if there are more than one). | |||

In fact, it can be seen from condition 3 that the haplotonic scale is up to 9 notes. | In fact, it can be seen from condition 3 that the haplotonic scale is up to 9 notes. | ||
By the way, many of the | By the way, many of the scale-lists listed on <nowiki>[[Chromatic pairs]]</nowiki> are actually "chain of albitonic-chromatic pairs". Moreover, the part that is a arithmetic sequence is composed by repeatedly adding the same strong haplotonic scale. And the strong haplotonic is direct parent MOS of first albitonic of the arithmetic chain. | ||

* What I mean of albitonic-chromatic pairs is strict operation of equation of condition 2. And with MOS tree, albitonic-chromatic relation usually results in direct parent-daughter. Exception is (1L ''x''s)+(1L ''y''s)=(1a (1+''x''+''y'')b) (i dunno another case). Or adopt [[User:Ganaram inukshuk/Notes #Strict definition|his strict definition]]. You can then use ''n''*(haplotonic)+(albitonic)=(...) to move a few steps at once (<q>possibly multiple copies of one of them</q>). | |||
~~ Exercise ~~ | |||
* I would like to exclude 1L ''x''s from the albitonic-chromatic pair. To reason this... excluding 1L from strong haplotonic. | |||
* First two strong haplotonic of Barton are Barton[2] and Barton[11]. Barton[2] is too few notes. Barton[11] is too many notes. Barton[3] and all descendants aren't semitone-free. Strong haplotonic can be obtained for any rank-2, but not always any haplotonic (in condition 1 and 3) can be. | |||
* Seni[5] and Sensi[8] both are labelled Category:Haplotonic scales. Only Sensi[8] is strong haplotonic, but Sensi[5] is shorter genchain, obviously more haplo than Sensi[8]. both haplotonic? mini-haplotonic and haplotonic? haplotonic and strong-haplotonic? Well, shouldn't both be haplotonic? Isn't it just that we want to differentiate it because we're trying to include it in the scale-list? | |||
** If there are multiple haplotonic scale in condition 1 and 3, it may be nice to name most-notes scale (must be strong haplotonic!) "strong haplotonic" or "maximum haplotonic" or "the end of haplotonic". | |||
*** Baldy[5] and Baldy[6] both are strong haplotonic, so we need to use different terms to distinguish them. e.g. Baldy4/5/6 are haplotonic and Baldy6 is max-haplotonic. Until Baldy5 become listed, Baldy6 is simply called haplotonic. | |||
