Original Wikitext content:
A trivial temperament is something that fits the mathematical definition of "regular temperament", but is a unique, extreme case that people might be uncomfortable calling a "temperament". There are two kinds of trivial temperaments - JI, in which nothing is tempered, and om temperament, in which everything is tempered.
Just intonation is a codimension-0 "temperament", which means nothing is tempered. The set of commas that are tempered out is the empty set, {}, but that's still a set, so JI is still a regular temperament. There is an infinite family of these "temperaments", one for each subgroup of JI. The 2-limit version is the equal temperament [[1edo]]. The 3-limit version is the rank-2 temperament [[pythagorean]], which has all the properties of any other rank-2 temperament except that it tempers no commas. The 5-limit version is rank-3, and so on.
Om temperament is the rank-0 temperament, in which every interval is a comma. Thus all notes are represented by the same note. This is different from 1edo because not even octaves exist.Original HTML content:
