In the modern western understanding of [[scale]]s, 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 ''tonic'' of the scale. Together, a tonic 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 tonic.

Octave-repeating [[harmonic series segment]]s are called ''harmonic modes'' by several musicians, although this implies a slightly 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 tonic (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 tonic.

* 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.
