Editing Locrian mode

{{Short description|Musical mode}}
The '''Locrian mode''' is the seventh mode of the major scale. It is either a [[Mode (music)|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==
''[[Locrians|Locria]]n'' is the word used to describe an ancient Greek tribe that inhabited the three regions of [[Locris]].<ref>{{OED|Locrian}}</ref> 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 [[Heinrich Glarean|Glarean's]] hyperaeolian mode, in either classical, Renaissance, or later phases of modal theory through the 18th&nbsp;century, or modern scholarship on ancient Greek musical theory and practice.<ref name=Powers-2001a>{{cite dictionary |first=Harold S. |last=Powers |title=Locrian |year=2001a |dictionary=The New Grove Dictionary of Music and Musicians |edition=2nd |editor1-first=Stanley |editor1-last=Sadie |editor1-link=Stanley Sadie |editor2-first=John |editor2-last=Tyrrell |editor2-link=John Tyrrell (professor of music) |place=London, UK |publisher=Macmillan Publishers |page=158 }}</ref><ref>{{cite book |first=David |last=Hiley |author-link=David Hiley |year=2002 |section=Mode |title=The Oxford Companion to Music |editor-first=Alison |editor-last=Latham |place=Oxford, UK / New York, NY |publisher=Oxford University Press |isbn=978-0-19-866212-9 |oclc=59376677 }}</ref>

The name first came into use in modal chant theory after the 18th&nbsp;century,<ref name=Powers-2001a/> when ''Locrian'' was used to describe the newly-numbered mode&nbsp;11, with its final on B, [[ambitus (music)|ambitus]] from that note to the octave above, and semitones therefore between the first and second, and between the fourth and fifth degrees. Its [[reciting tone]] (or tenor) is G, its [[mediant]]&nbsp;D, and it has two [[Musical mode#Western Church|participant]]s: E and F.<ref>{{cite dictionary |first=William Smyth |last=Rockstro |year=1880 |title=Locrian mode |dictionary=A Dictionary of Music and Musicians (A.D. 1450–1880), by eminent writers, English and foreign |volume=2 |editor-first=George, D.C.L. |editor-last=Grove |editor-link=George Grove |place=London, UK |publisher=Macmillan and Co. |page=158 }}</ref> The [[final (music)|final]], as its name implies, is the tone on which the chant eventually settles, and corresponds to the tonic in tonal music.

==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.

==Overview==
The Locrian mode is the only modern diatonic mode in which the [[tonic chord|tonic triad]] is a [[diminished triad|diminished chord]] ([[diminished fifth|flattened fifth]]), which is considered very [[consonance and dissonance|dissonant]]. This is because the interval between the [[root (chord)|root]] and fifth of the chord is a [[tritone|diminished fifth]]. For example, the tonic triad of B&nbsp;Locrian is made from the notes B, D, F. The root is B and the [[diminished (music)|dim]]&nbsp;5th is F. The diminished-fifth interval between them is the cause for the chord's striking dissonance.{{citation needed|date=January 2018}}

The name "Locrian" is borrowed from music theory of [[Music of ancient Greece|ancient Greece]]. However, what is now called the ''Locrian mode'' was what the Greeks called the [[Mixolydian mode#Greek Mixolydian|diatonic ''Mixolydian'' tonos]]. The Greeks used the term "Locrian" as an alternative name for their "[[Hypodorian mode|Hypodorian]]", or "common" tonos, with a scale running from ''mese'' to ''nete hyperbolaion'', which in its diatonic genus corresponds to the modern [[Aeolian mode]].<ref>{{cite dictionary |first=T.J. |last=Mathiesen |author-link=Thomas J.

In his reform of modal theory,<ref>{{cite book |first=H. |last=Glarean |author-link=Heinrich Glarean |year=1547 |title=Dodecachordon }}</ref>  [[Heinrich Glarean|Glarean]] named this division of the octave "hyperaeolian" and printed some musical examples (a three-part polyphonic example specially commissioned from his friend [[Sixtus Dietrich]], and the Christe from a mass by [[Pierre de La Rue|{{nobr|de la Rue}}]]), though he did not accept hyperaeolian as one of his twelve modes.<ref name=Powers-2001c>{{cite dictionary |first=Harold S. |last=Powers |title=Hyperaeolian |year=2001c |dictionary=[[The New Grove Dictionary of Music and Musicians]] |edition=2nd |editor1-first=Stanley |editor1-last=Sadie |editor1-link=Stanley Sadie |editor2-first=John |editor2-last=Tyrrell |editor2-link=John Tyrrell (professor of music) |place=London, UK |publisher=Macmillan Publishers |pages= }}</ref> 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&nbsp;century.<ref name=Powers-2001a/>

* [[Paul Hindemith]]'s "Turandot Scherzo", the theme of the second movement of ''[[Symphonic Metamorphosis of Themes by Carl Maria von Weber]]'' (1943) alternates sections in [[mixolydian mode|mixolydian]] and Locrian modes, ending in Locrian.<ref>{{cite conference |first=Gene |last=Anderson |year=1996 |title=&hairsp;''The triumph of timelessness over time in Hindemith's "Turandot Scherzo" from'' Symphonic Metamorphosis of Themes by Carl Maria von Weber |conference=College Music Symposium |volume=36 |pages=1–15, citation p&nbsp;3 }}</ref>
* [[Benjamin Britten]] used the Locrian mode for "In Freezing Winter's Night", the ninth song in ''[[A Ceremony of Carols]]''.
* Evan Bennett, an American composer, composed his Gnossienne No. 1 in F Locrian in the Locrian mode, in homage to [[Erik Satie]]’s [[Gnossiennes|Gnossienne No. 1]] (ca. 1890).<ref>{{cite web |date=6 March 2024 |title=Using Modes to Compose: Locrian |last=Mair |first=Nadia |url=https://www.nadiamair.com/post/using-modes-to-compose-locrian |website=The Composer's Life |access-date=30 May 2025}}</ref><ref>{{cite web |date=17 February 2023 |title=Songs in the Locrian Mode |url=https://www.cmuse.org/songs-in-locrian-mode/ |website=CMUSE |access-date=28 May 2025}}</ref>

===Use in folk and popular music===
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]."<ref name=Rooksby-2010>{{cite book |last=Rooksby |first=Rikky |year=2010 |title=Riffs: How to create and play great guitar riffs |publisher=Backbeat |isbn=9781476855486 |page=[https://books.google.com/books?id=ftGGDwAAQBAJ&dq=Locrian+mode&pg=PT121 121] |url=https://books.google.com/books?id=ftGGDwAAQBAJ |via=Google books }}</ref>

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

* The Locrian is used in [[Middle Eastern music]] as ''maqam Lami''.<ref>{{Cite web |title=Maqam Lami |url=https://www.maqamworld.com/en/maqam/lami.php |access-date=2025-01-01 |website=www.maqamworld.com}}</ref> In 24 TET, it is possible to create 12 TET scales, and Lami has the same intervals as Locrian.
* [[Slipknot (band)|Slipknot]]'s track "[[Iowa (album)|Everything Ends]]" uses an A Locrian scale with the fourth note sometimes flattened.<ref name=Rooksby-2010/>
* English folk musician [[John Kirkpatrick (folk musician)|John Kirkpatrick]]'s song "Dust to Dust" was written in the Locrian mode,<ref>{{cite web |last=Boden |first=Jon |author-link=Jon Boden |date=21 April 2012 |title="Dust to Dust" |website=A Folk Song a Day (afolksongaday.com) |url=http://www.afolksongaday.com/2012/04/21/dust-to-dust/ |archive-url=https://web.archive.org/web/20121003032910/http://www.afolksongaday.com/2012/04/21/dust-to-dust/ |url-status=dead |archive-date=3 October 2012 }}</ref> backed by his [[concertina]].
