The '''period''' of a [[~~MOS~~ scale]] is the interval at which the ~~MOS~~ pattern repeats. Another word for the period is the '''interval of repetition'''. It is usually the same size as the [[equave]] (interval of equivalence) or a fraction thereof. ~~Along with the~~ [[~~generator~~]], it is one of the two defining intervals ~~of a MOS~~. For example:

The '''period''' of a [[scale]] is the interval at which the scale pattern repeats. Another word for the period is the '''interval of repetition'''. A scale with a period is known as a [[periodic scale]]. The period is usually the same size as the [[equave]] (interval of equivalence) or a fraction thereof.

In [[mos scale]]s, the period is one of the two defining intervals, the other being the [[generator]]. For example:

* The diatonic scale (LLsLLLs) has period equal to the octave.

* The diminished scale (sLsLsLsL) has period 1\4, ~~because~~ the ~~MOS~~ pattern sL repeats at every 300 cents.

* The diminished scale (sLsLsLsL) has period 1\4, since the mos pattern sL repeats at every 300 cents.

The same definition applies for a [[rank]]-2 temperament, when the temperament is seen as generating a ~~MOS~~. Every interval of a rank-2 temperament is a sum of some number of the period and some number of the generator of the temperament.

The same definition applies for a [[rank]]-2 temperament, when the temperament is seen as generating a mos. Every interval of a rank-2 temperament is a sum of some number of the period and some number of the generator of the temperament.
