The term '''mode''' of the modern western understanding of scales is determined by the starting/ending point of a scale based on a given tonal material.

In the modern western understanding of scales, a '''mode''' (or '''rotation''') of a [[periodic scale]] is an ordering of the scale's tones determined by choosing one of the tones as the starting/ending point.
For example the diatonic material 0 2 4 5 7 9 11 12 14 16 17 ... of [[12edo]] with its 7-tone periodicity (12 equals 0) can be used to build 7 different modes, which are often named as


For example, the [[5L 2s|diatonic]] material 0 2 4 5 7 9 11 12 14 16 17 ... of [[12edo]] with its 7-tone [[period]]icity (12 equals 0) can be used to build 7 different modes, which are often named as:
* Ionian (0...)
* Ionian (0...)
* Dorian (2...)
* Dorian (2...)

Modes are mostly used in the context of tonal or modal music, i.e. as opposed to atonal music, since their definition implies a pitch center.
== Properties ==
A scale has as many modes as the number of tones that it contains within a period. For example:
* the diatonic scale has 7 modes, because it has 7 tones per period of 1 octave;
* the octatonic [[diminished scale]] only has 2 modes, because it has 2 tones per period of 1/4 octave.
In an [[equal-step tuning]], any mode of any [[support]]ed scale can be built on any tone of the chosen tuning, i.e. it is possible to transpose to any key while keeping the same scale and mode.
