Locrian mode

Source: Wikipedia, the free encyclopedia.

The Locrian mode is the seventh mode of the major scale. It is either a musical mode or simply a diatonic scale. On the piano, it is the scale that starts with B and only uses the white keys from there on up to the next higher B. Its ascending form consists of the key note, then: Half step, whole step, whole step, half step, whole step, whole step, whole step.

History

Locrian is the word used to describe an ancient Greek tribe that habited the three regions of Locris.[1] Although the term occurs in several classical authors on music theory, including Cleonides (as an octave species) and Athenaeus (as an obsolete harmonia), there is no warrant for the modern use of Locrian as equivalent to Glarean's hyperaeolian mode, in either classical, Renaissance, or later phases of modal theory through the 18th century, or modern scholarship on ancient Greek musical theory and practice.[2][3]

The name first came into use in modal chant theory after the 18th century,

plagal forms, coincident with the reciting tone of the corresponding authentic mode.[6]

Modern Locrian

In modern practice, the Locrian may be considered to be one of the modern

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, or modern natural major scale
. The Locrian mode has the formula:

1, ♭2, ♭3, 4, ♭5, ♭6, ♭7

The chord progression for Locrian starting on B is Bdim 5, CMaj, Dmin, Emin, FMaj, GMaj, Amin. Its

tonic chord is a diminished triad (Bdim = Bdim 5
min 3 = BDF, in the Locrian mode using the white-key diatonic scale with starting note B, corresponding to a C major scale starting on its 7th 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.

Overview

The Locrian mode is the only modern diatonic mode in which the

dim 5th is F. The diminished-fifth interval between them is the cause for the chord's striking dissonance.[citation needed

The name "Locrian" is borrowed from music theory of ancient Greece. However, what is now called the Locrian mode was what the Greeks called the diatonic Mixolydian tonos. The Greeks used the term "Locrian" as an alternative name for their "Hypodorian", or "common" tonos, with a scale running from mese to nete hyperbolaion, which in its diatonic genus corresponds to the modern Aeolian mode.[7]

In his reform of modal theory,

de la Rue), though he did not accept hyperaeolian as one of his twelve modes.[9] The use of the term "Locrian" as equivalent to Glarean's hyperaeolian or the ancient Greek (diatonic) mixolydian, however, has no authority before the 19th century.[2]

Use

Used in orchestral music

There are brief passages that have been, or may be, regarded as being in the Locrian mode in orchestral works by

The Locrian mode is almost never used in folk or popular music:

"In practical terms it should be said that few rock songs that use modes such as the Phrygian, Lydian, or Locrian actually maintain a harmony rigorously fixed on them. What usually happens is that the scale is harmonized in [chords with perfect] fifths and the riffs are then played [over] those [chords]."[13]

Among the very few instances of folk & popular music in the Locrian mode:
