User:CompactStar/Ordinal interval notation

Lefts and rights notation is a notation for just intonation primarily developed by CompactStar.

Explanation

Regular names corresponds to Pythagorean tuning, e.g. 32/27 is a minor third. To name non-Pythagorean intervals, they are given the name of a nearby Pythagorean interval (see #Mapping non-Pythagorean intervals) then prefixed with a sequence of lefts and rights (abbreviated as < and > respectively).
