For a long time, theorists used the term "equal temperament" for edos designed to approximate low-complexity just intervals. The same term is still used today to designate more generally all rank-1 [[Regular temperament|temperaments]]. For example, [[15edo]] can be referred to as 15-tone equal temperament (15-TET, 15-tET, 15tet, etc.), or more simply 15 equal temperament (15-ET, 15et, etc.). | For a long time, tuning theorists used the term "equal temperament" for edos designed to approximate low-complexity just intervals.

A few more alternate notations have been devised by some musicians more recently, including "edd" or "EDD" (equal divisions of the [[Ditave]]), "DIV," and "EQ." | A few more alternate notations have been devised by some musicians more recently, including "edd" or "EDD" (equal divisions of the [[Ditave]]), "DIV," and "EQ." | ||
