'''MOS substitution'''{{idiosyncratic}} is a procedure for obtaining a ternary (3 step sizes) scale from two [[MOS scale]]s. It consists of substituting the step pattern of one MOS pattern (called the filling MOS), scale step for scale step, for all occurrences of a chosen step size of another MOS pattern (called the template MOS). Unlike MV3 scales, a MOS substitution scale may have any combination of step sizes. | '''MOS substitution'''{{idiosyncratic}} is a procedure for obtaining a ternary (3 step sizes) scale from two [[MOS scale]]s.

For example, if the template MOS is '''LXLXX''', and the filling MOS is '''mss''', then the resulting MOS substitution scales are '''LmLss''', '''LsLms''', and '''LsLsm'''. | For example, if the template MOS is '''LXLXX''', and the filling MOS is '''mss''', then the resulting MOS substitution scales are '''LmLss''', '''LsLms''', and '''LsLsm'''. This is written "subst 2L(1m2s)". | ||
Under defined conditions, MOS substitution scales have the advantage of having a [[generator sequence]]. | Under defined conditions, MOS substitution scales have the advantage of having a [[generator sequence]]. | ||
