User:CompactStar/RST notation: Difference between revisions

'''RST notation''' is a [[notation] for [[just intonation]] (also supporting JI-based [[regular temperaments]] ), that was devised by [[User:CompactStar|CompactStar]]. It is an extension of [[3-limit]] [[chain-of-fifths notation]] where prefixes are added to convey higher-limit commatic alterations. The prefixes used are "ruper-"/"rub-" for the 5-limit formal comma [[81/80]], "super-"/"sub-" for the 7-limit formal comma [[64/63]], "tuper-"/"tub-" for the 11-limit formal comma [[33/32]], etc., going through a rotated version of the alphabet (RSTUVWXYZABCDEFGHIJKLMNOPQ). These may be abbreviated as R/r, S/s, T/t, etc. This is a generalization of the usage of super-/sub- for [[64/63]] which has existing precedent like in "subminor 7th" for [[7/4]]. Diphthongs have the second vowel removed for ease of pronunciation (for example "iuper-"/"iub-" -> "iper-"/"ib-") and "cuper-"/"cub-" is modified to "chuper-"/"chub-" to reduce ambiguity.
