The Dorian mode or Doric mode can refer to three very different but interrelated subjects: one of the ancient harmoniai (characteristic melodic behaviour, or the scale structure associated with it); one of another ancient 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 enharmonic genus, the intervals in each tetrachord are quarter tone–quarter tone–major third.
In the chromatic genus, they are semitone–semitone–minor third.
In the diatonic genus, they are semitone–tone–tone.
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:
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:
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.
The modern Dorian mode is equivalent to the natural minor scale (or the Aeolian mode) but with a major sixth. The modern Dorian mode resembles the Greek Phrygian harmonia in the diatonic genus.
It is also equivalent to the ascending melodic minor scale with a minor seventh.

The Dorian mode or Doric mode can refer to three very different but interrelated subjects: one of the ancient harmoniai (characteristic melodic behaviour, or the scale structure associated with it); one of another ancient 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 Hypodorian mode, a musical term literally meaning 'below Dorian', derives its name from a tonos or octave species of ancient Greece which, in its diatonic genus, is built from a tetrachord consisting (in rising direction) of a semitone followed by two whole tones. The rising scale for the octave is a single tone followed by two conjoint tetrachords of this type. This is roughly the same as playing all the white notes of a piano from A to A: A | B C D E | (E) F G A. Although this scale in medieval theory was employed in Dorian and Hypodorian, from the mid-sixteenth century and in modern music theory they came to be known as the Aeolian and Hypoaeolian modes. The term Hypodorian came to be used to describe the second mode of Western church music. This mode is the plagal counterpart of the authentic first mode, which was also called Dorian. The ecclesiastical Hypodorian mode was defined in two ways: (1) as the diatonic octave species from A to A, divided at the mode final D and composed of a lower tetrachord of tone–semitone–tone, ending on D, plus a pentachord tone–semitone–tone–tone continuing from D, and (2) as a mode whose final was D and whose ambitus was G–B♭ (that is, with B♮ below the final and B♭ above it). In addition, the note F, corresponding to the reciting note or tenor of the second psalm tone, was regarded as an important secondary center.
In music, the Ukrainian Dorian scale (Dorian ♯4 scale) or the Lydian ♭3 ♭7 scale is a scale that is the same as the Dorian mode of Western music, except with a raised 4th scale degree. Compared with a major scale, it has a lowered third and seventh (like Dorian mode) and a raised fourth (like Lydian mode). Its scale degrees are: 1, 2, ♭3, ♯4, 5, 6, ♭7, 8. It has traditionally been common in the music of Eastern Europe, Southeast Europe, and the Mediterranean including Jewish, Greek, Ukrainian, and Romanian music. Because of its widespread use, this scale has been known by a variety of names including Altered Dorian, Hutsul mode and Mi Shebeirach. It is also closely related to the Nikriz pentachord found in Turkish or Arabic maqam systems. It is equivalent to the scale of the Indian raga Hemavati.
The Dorian ♭2 scale (pronounced "Dorian flat two"), also known as the Phrygian ♮6 scale (Phrygian sharp six), or the Javanese scale is the second mode of the jazz minor scale (or the ascending melodic minor scale). It is on the second degree of the jazz minor scale. Without the minor second above the root, the scale would just be the Dorian mode. The reason it is also known as Phrygian ♮6 is because if the scale did not have the major 6th then it would be enharmonic with the Phrygian mode. This scale is commonly used in Assyrian music, most especially in the folk dance genre. Thought to add color and to retain the Phrygian tradition of Assyrian music, the major sixth may at times be simultaneously altered to the minor sixth during the course of the composition.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
