Authentic Gregorian mode From Wikipedia, the free encyclopedia
Dorian mode or Doric mode can refer to three very different but interrelated subjects: one of the Ancient Greekharmoniai (characteristic melodic behaviour, or the scale structure associated with it); one of the medieval musical modes; or—most commonly—one of the modern modal diatonic scales, corresponding to the piano keyboard's white notes from D to D, or any transposition of itself.
The Dorian mode (properly harmonia or tonos) is named after the Dorian Greeks. Applied to a whole octave, the Dorian octave species was built upon two tetrachords (four-note segments) separated by a whole tone, running from the hypate meson to the nete diezeugmenon.
In the diatonic genus, the sequence over the octave is the same as that produced by playing all the white notes of a piano ascending from E to E,[1] a sequence equivalent to the pattern of the modern Phrygian mode, although the temperament differs by small amounts.
Placing the single tone at the bottom of the scale followed by two conjunct tetrachords (that is, the top note of the first tetrachord is also the bottom note of the second), produces the Hypodorian ("below Dorian") octave species: A | B C D E | (E) F G A. Placing the two conjunct tetrachords together and the single tone at the top of the scale produces the Mixolydian octave species, a note sequence equivalent to modern Locrian mode.[2]
The early Byzantine church developed a system of eight musical modes (the octoechos), which served as a model for medieval European chant theorists when they developed their own modal classification system starting in the 9th century.[3] The success of the Western synthesis of this system with elements from the fourth book of De institutione musica of Boethius, created the false impression that the Byzantine octoechos was inherited directly from ancient Greece.[4]
Originally used to designate one of the traditional harmoniai of Greek theory (a term with various meanings, including the sense of an octave consisting of eight tones), the name was appropriated (along with six others) by the 2nd-century theorist Ptolemy to designate his seven tonoi, or transposition keys. Four centuries later, Boethius interpreted Ptolemy in Latin, still with the meaning of transposition keys, not scales. When chant theory was first being formulated in the 9th century, these seven names plus an eighth, Hypermixolydian (later changed to Hypomixolydian), were again re-appropriated in the anonymous treatise Alia Musica. A commentary on that treatise, called the Nova expositio, first gave it a new sense as one of a set of eight diatonic species of the octave, or scales.
In medieval theory, the authentic Dorian mode could include the note B♭ "by licence", in addition to B♮.[5] The same scalar pattern, but starting a fourth or fifth below the mode final D, and extending a fifth above (or a sixth, terminating on B♭), was numbered as mode 2 in the medieval system. This was the plagal mode corresponding to the authentic Dorian, and was called the Hypodorian mode.[6] In the untransposed form on D, in both the authentic and plagal forms the note C is often raised to C♯ to form a leading tone, and the variable sixth step is in general B♮ in ascending lines and B♭ in descent.[7]
The modern Dorian mode (also called "Russian minor" by Balakirev,[8]) by contrast, is a strictly diatonic scale corresponding to the white keys of the piano from D to D (shown below)
or any transposition of its interval pattern, which has the ascending pattern of whole steps and half steps as follows:
whole, half, whole, whole, whole, half, whole
Thus, the Dorian mode is a symmetric scale, since the pattern of whole and half steps is the same ascending or descending.
The modern Dorian mode can also be thought of as a scale with a minor third and seventh, a major second and sixth, and a perfect fourth and fifth, notated relative to the major scale as:
1, 2, ♭3, 4, 5, 6, ♭7, 8
It may be considered an "excerpt" of a major scale played from the pitch a whole tone above the major scale's tonic, i.e., a major scale played from its second scale degree up to its second degree again. The resulting scale is, however, minor in quality, because, as the D becomes the new tonal centre, the F a minor third above the D becomes the new mediant, or third degree. Thus, when a triad is built upon the tonic, it is a minor triad.

La Manfredina, a 14th-century monophonic Italian dance in two parts, with the second section designated "La Rotta della Manfredina" (British Library, Add MS 29987, No. 92).
In "La Brise" (from the Mélodies Persanes, Op. 26), Saint-Saëns uses an E Dorian scale in the first half of the song.[19]
Jazz
"Maiden Voyage" by Herbie Hancock[20] – The composition takes an AABA form with chords in the "A" sections in D Dorian and the "B" section in E♭ Dorian.
"Dorian" by First of October. The song uses the modern Dorian scale on the piano during the choruses to build tension, while staying in the key of D minor for the verses and melody.
The chord sequence i–III–VII–IV is sometimes used in pop songs, where the harmonic rhythm leads the listener to think of it as a minor song. In the final chord of the sequence, however, the third is a major sixth above the tonic, as in the Dorian scale. Examples include: "Mad World" by Tears for Fears.[26]
"The Night The Lights Went Out In Georgia" (1973) by Vicki Lawrence
"Rapper's Delight" by Sugarhill Gang is often written in E minor with a persistent C♯ accidental,[28] but is actually played in E Dorian.[29] It shares a key signature (F♯, C♯) with its relative key, D major.[30]
"Tick Tock" by Clean Bandit (and Mabel) sounds heavily pentatonic, but is in fact (nominally) in the 'D' Dorian mode.
The Halo theme, taking significant inspiration from the aforementioned medieval Gregorian chants to effect an "ancient and mysterious" sound, is written in E dorian
