Dorian mode
The Dorian mode is a diatonic musical scale or mode that serves as the second mode of the major scale, constructed by starting on the second degree of any major scale and following the interval pattern of whole step, half step, whole step, whole step, whole step, half step, whole step (WHWWWHW).[1] In terms of scale degrees, it features a minor third and a major sixth from the tonic, distinguishing it from the natural minor (Aeolian) scale by raising the sixth degree by a half step, which imparts a brighter, more ambiguous tonality between minor and major sounds.[1] For example, D Dorian uses the notes D, E, F, G, A, B, C, sharing the key signature of C major but emphasizing the modal flavor through the raised sixth (B natural).[2] Originating in ancient Greek music theory, the Dorian mode was one of the harmoniai—characteristic melodic patterns named after ethnic tribes or regions, with the Dorian linked to the Dorian people of Greece and described as a "manner" or style evoking manly, warlike, and morally elevating qualities.[3] Philosophers like Plato praised it for fostering self-discipline and rational harmony in the soul, recommending it in education (paideia) while rejecting softer modes like Lydian for promoting vice.[3] During the medieval period, the Dorian mode evolved into one of the eight church modes in Western sacred music, classified as the first authentic mode (from D to D) with its plagal counterpart (Hypodorian) spanning from A to A, used extensively in Gregorian chant and polyphony for its stable, non-tonal structure lacking a strong leading tone. By the Renaissance and Baroque eras, modal practices began shifting toward tonal major-minor systems, but Dorian persisted in compositions requiring modal authenticity.[4] In modern music, the Dorian mode remains prominent in jazz, rock, folk, and film scores for its versatile, melancholic yet hopeful character, often employed over minor ii chords in functional harmony or as a standalone scale.[5] Notable examples include Miles Davis's "So What" (1959), which centers on D Dorian for its modal jazz foundation; the traditional English folk song "Scarborough Fair," rendered in the mode's characteristic raised sixth; Jean Sibelius's Symphony No. 6 (1923), which draws on Dorian elements for its introspective lyricism; and Claude Debussy's Rêverie (1890), where the Dorian mode contributes to its impressionistic ambiguity.[6] Its lack of avoid notes makes it ideal for improvisation, particularly in jazz, and its adaptability continues to influence contemporary genres from funk to progressive rock.[5]Overview
Definition and Etymology
The Dorian mode is a diatonic scale comprising seven notes arranged in the stepwise interval pattern of whole step, half step, whole step, whole step, whole step, half step, whole step.[7] It functions as the second mode within the series of seven diatonic modes derived from the major scale, constructed by beginning on that scale's second degree while preserving the overall pitch content.[7] The name "Dorian" derives from ancient Greek musical theory, where it designated one of the principal harmoniai, or melodic frameworks, associated with the Dorian ethnic group, a major Hellenic tribe centered in regions like Doris and the Peloponnese. Ancient theorists such as Aristoxenus (c. 375–335 BCE) described the Dorian harmonia as a balanced, austere structure suitable for ethical and martial expression, while Ptolemy (c. 100–170 CE) systematized it within his octave-species framework as the central, normative mode spanning from E to E in a diatonic tuning.[8] These designations reflected not just scalar patterns but also perceived emotional and cultural attributes linked to Dorian identity.[9] In the Renaissance, the term was revived and adapted by humanist music theorists to reclassify medieval church modes with classical Greek nomenclature, aiming to align contemporary practice with antiquity. Heinrich Glarean, in his influential 1547 treatise Dodecachordon, assigned "Dorian" to the mode with D as its finalis (the first of the authentic modes), positioning it as a cornerstone of the expanded twelve-mode system and evoking its ancient precedents for pedagogical and compositional purposes.[10] This revival integrated the Dorian into Western modal theory as a minor-like scale with a distinctive raised sixth degree relative to the natural minor. The Dorian belongs to the broader diatonic mode family, alongside relatives such as the Ionian (major) and Aeolian (natural minor).[7]Scale Construction and Intervals
The Dorian mode is constructed using a specific sequence of whole steps (W) and half steps (H), following the pattern W-H-W-W-W-H-W. This pattern produces a diatonic scale with seven notes per octave, where the intervals from the tonic are a major second (two semitones), minor third (three semitones), perfect fourth (five semitones), perfect fifth (seven semitones), major sixth (nine semitones), and minor seventh (ten semitones).[11][1] As the second mode of the major scale, the Dorian mode shares all pitches with its parent major scale but begins and ends on the second degree, creating a distinct tonal center. For example, D Dorian derives from the C major scale and consists of the notes D-E-F-G-A-B-C-D, employing no sharps or flats in this transposition.[11][1] In the circle of fifths, the Dorian mode on a given tonic shares its key signature with the major scale whose tonic is a whole step below (i.e., the mode's tonic is the supertonic of the parent major scale). For instance, D Dorian aligns with C major at the circle's neutral position (no accidentals), facilitating key relationships in harmonic progressions. Enharmonic equivalents of the Dorian scale occur in transpositions involving double sharps or flats, such as C♯ Dorian (with five sharps) being equivalent in pitch to D♭ Dorian (with five flats), though the former is theoretically constructed while the latter uses standard key signatures.[11][1][12] The following table compares the semitone intervals from the tonic for the Dorian mode against the Ionian (major) and Aeolian (natural minor) modes:| Degree | Ionian (Major) | Dorian | Aeolian (Natural Minor) |
