'''RST notation''' is a [[notation]] for [[just intonation]] and [[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 for formal commas are obtained by going through a ~~truncated~~ version of the alphabet (~~RSTUVWXYZ~~) and appending "uper"/"ub". If the letter is a vowel we discard the first "u". Thus the formal comma for 5 has the prefix pair "ruper-"/"rub-", 7 has the prefix pair "super-"/"sub-", 11 has prefix pair "tuper-"/"tub-"~~, etc~~. These are abbreviated as R/r, S/s, T/t, etc. This system is a generalization of the widespread usage of the Latin prefixes super-/sub- for alteration of Pythagorean intervals by [[64/63]] which, although ad-hoc, has the advantage of being easily typable and fairly easily memorizable.

Iit is an extension of [[3-limit]] [[chain-of-fifths notation]] where prefixes are added to convey higher-limit commatic alterations. The prefixes for formal commas are obtained by going through a shifted version of the alphabet (RSTUVWXYZABCDEFGHIJKLMNOPQ) and appending "uper"/"ub". if the letter is a vowel we discard the first "u". Thus the formal comma for 5 has the prefix pair "ruper-"/"rub-", 7 has the prefix pair "super-"/"sub-", 11 has prefix pair "tuper-"/"tub-". These are abbreviated as rp/rb, sp/sb, tp/tb, etc. This system is a generalization of the widespread usage of the Latin prefixes super-/sub- for alteration of Pythagorean intervals by [[64/63]] which, although ad-hoc, has the advantage of being easily typable and fairly easily memorizable. "Cuper-"/"cub-" is modified to "chuper-"/"chub-" to avoid pronunciation conflicts with "kuper-"/"kub-".
