Editing Locrian mode (section)

==Modern Locrian==
In modern practice, the Locrian may be considered to be one of the modern [[minor scale]]s: The [[natural minor]] with the  [[Minor second| step before second]] and the [[diminished fifth|fifth]] scale degrees reduced from a tone to a [[semitone]]. The Locrian mode may also be considered to be a scale beginning on the seventh scale degree of any [[Ionian mode|Ionian]], or modern natural [[major scale]]. The Locrian mode has the formula:

: 1, {{sup|{{music|b}}}}2, {{sup|{{music|b}}}}3, 4, {{sup|{{music|b}}}}5, {{sup|{{music|b}}}}6, {{sup|{{music|b}}}}7
The chord progression for Locrian starting on B is B{{sub|dim&nbsp;5}}, C{{sup|Maj}}, D{{sub|min}}, E{{sub|min}}, F{{sup|Maj}}, G{{sup|Maj}}, A{{sub|min}}.
Its [[tonic chord]] is a [[diminished triad]] (B{{sub|dim}} = B{{su|b=min&nbsp;3|p=dim&nbsp;5}} = {{sub|B}}{{small|{{small|D}}}}{{sup|F}}, in the Locrian mode using the white-key diatonic scale with starting note&nbsp;B, corresponding to a C&nbsp;major scale starting on its 7th&nbsp;tone). This mode's diminished fifth and the [[Lydian mode]]'s augmented fourth are the only modes that contain a [[tritone]] as a note in their modal scale.
