The concept of MOS scales were invented by Erv Wilson in 1975 in his paper ''Moments of Symmetry''. A moment-of-symmetry scale consists of:
Erv Wilson's 1975 paper ''Moments of Symmetry'' provides the original definition of a moment-of-symmetry scale. A moment-of-symmetry scale consists of:


* A generator and an [[equivalence interval]], called the period, which is usually the [[octave]].
* A generator and an [[equivalence interval]], called the period, which is usually the [[octave]].
