Monotone-MOS scale

A ternary scale in L > M > s > 0 is monotone-MOS if it becomes a MOS under all three of the identifications L = M, M = s, and s = 0. If any (not necessarily all) of the identifications make the scale a MOS, the scale is said to satisfy a monotone-MOS property. This property is used in aberrismic theory.

Regular MV3 scales satisfy all 3 properties and hence are monotone-MOS. They are also deletion-MOS scales.

The term monotone-MOS was coined by Tom Price.
