-A scale is '''distributionally even (DE)''' if it has [[maximum variety]] 2; that is, each class of interval ("seconds", "thirds", and so on) contains '''no more than''' two specific intervals.
+A scale is '''distributionally even''' ('''DE''') if it has [[maximum variety]] 2; that is, each generic interval class ("seconds", "thirds", and so on) contains no more than two specific intervals.
-In practice, such scales are often referred to as "[[MOS scale]]s", but some consider this usage to be technically incorrect because a MOS as defined by [[Erv Wilson]] was to have '''exactly''' two specific intervals for each class other than multiples of the octave. When Wilson discovered MOS scales and found numerous examples, DE scales with period a fraction of an octave such as [[pajara]], [[Augmented family|augmented]], [[diminished]], etc. were not among them.
