=== Basic properties ===
* Every MOS scale has two ''child MOS'' scales. The two children of the MOS scale aL bs are (a + b)L as (corresponding to soft-of-basic aLbs) and aL (a + b)s (corresponding to hard-of-basic aLbs).
* Every MOS scale (with a specified [[equave]] ''E''), excluding aL as⟨''E''⟩, has a ''parent MOS''. If a > b, the parent of aLbs is min(a, b)L|a &minus; b|s; if a < b, the parent of aLbs is |a &minus; b|L min(a, b)s.
