The '''period''' of a [[MOS]] is the interval at which the MOS pattern repeats | The '''period''' of a [[MOS]] is the interval at which the MOS pattern repeats. Another word for the period is the interval of repetition. It is usually also the [[interval of equivalence]]. Its size is usually an octave or a fraction thereof. Along with the [[generator]], it is one of the two defining intervals of a MOS. For example: | ||
* The diatonic scale (LLsLLLs) has period equal to the octave. | * 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, because the MOS pattern sL repeats at every 300 cents. | ||
