Step pattern: Difference between revisions

Line 5:

For an [[octave]]-repeating scale, the step pattern usually spans an octave; more generally, for a [[periodic scale]], the step pattern usually spans a [[period]] or an [[equave]]. Different rotations of the same step pattern can be used to express different [[mode]]s.

A scale pattern may be condensed into a '''scale signature''', displaying only the number of steps of any given size, no matter where they occur in the scale. For example, the scale signature for the diatonic scale, LLsLLLs, is [[5L 2s]]. In some cases, the scale signature can be used to uniquely identify a scale: for example, given a [[binary]] scale signature (aL bs), there is only one possible [[MOS scale]] with that signature.
