{{Main|Diatonic scale}}
A diatonic scale is any seven-note scale constructed sequentially using only whole tones and half tones, repeating at the octave, having a tonal center, and comprising only one [[tritone]] interval between any two scale members, which ensures that the half tone intervals are as far apart as possible. In Western music, there are seven such scales, and they are commonly known as the [[Mode (music)|modes]] of the [[major scale]] ([[Ionian mode|Ionian]], [[Dorian mode|Dorian]], [[Phrygian mode|Phrygian]], [[Lydian mode|Lydian]], [[Mixolydian mode|Mixolydian]], [[Aeolian mode|Aeolian]], and [[Locrian mode|Locrian]]).
