In the modern western understanding of ~~scales~~, a '''mode''' (or '''rotation''') of a [[periodic scale]] is an ordering of the scale's [[pitch class]]es determined by choosing one of the pitch classes as the starting/ending point. The chosen pitch class is the ''~~'tonal center'~~'' of the ~~mode~~. Together, a ~~tonal center~~ and a mode form a '''key'''.

The chosen pitch class is the ''[[tonic]]'' of the scale. Together, a tonic and a mode form a '''key'''.

Modes are mostly used in the context of tonal or modal music, i.e. as opposed to atonal music, since their definition implies a ~~tonal center~~.

Octave-repeating [[harmonic series segment]]s are called ''harmonic modes'' by several musicians, although this implies a slightly different definition of ''mode''.

The [[5L 2s|diatonic]] ~~scale~~ has seven different modes. The following table shows the modes of the diatonic scale built on the white keys (C-D-E-F-G-A-B) and in the key of D. The modes can be sorted according to their ~~tonal center~~ (sort by note names (white keys)) or their position in the [[circle of fifths]] (sort by step pattern)

== 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 different modes, because it has 7 tones per period of 1 octave, and 7 possible keys as well;

* The diatonic scale has 7 different modes, because it has 7 tones per period of 1 octave, and 7 possible keys as well;

* ~~the~~ octatonic [[diminished scale]] only has 2 different modes, because it has 2 tones per period of 1/4 octave, but it has 8 possible keys, since any of the 8 pitch classes of the scale can be chosen as the ~~tonal center~~.

* The octatonic [[diminished scale]] only has 2 different modes, because it has 2 tones per period of 1/4 octave, but it has 8 possible keys, since any of the 8 pitch classes of the scale can be chosen as the tonic.

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. In unequal tunings, each key can have a different scale pattern, therefore different but somewhat similar-sounding modes, which leads to a phenomenon called ''key coloration''.
