Modern Mixolydian scale on C[1] About this sound Play (help·info).

Mixolydian mode may refer to one of three things: the name applied to one of the ancient Greek harmoniai or tonoi, based on a particular octave species orscale; one of the medieval church modes; a modern musical mode or diatonic scale, related to the medieval mode.

[edit]Greek Mixolydian

The idea of a Mixolydian mode comes from the music theory of ancient Greece. The ancient Greek Mixolydian mode was invented by Sappho, the 7th century B.C. poet and musician.[2] However, what the ancient Greeks thought of as Mixolydian was very different from the modern interpretation of the mode.

In Greek theory, the Mixolydian mode (or tonos) employs a scale (or ‘octave species‘) corresponding to the Greek Hypolydian mode inverted: in its diatonic genus, this is a scale descending from paramese to hypate hypaton: in the diatonic genus, a whole tone (paramese to mese) followed by two conjunct inverted Lydiantetrachords (each being two whole tones followed by a semitone descending). This is the equivalent of playing all the ‘white notes’ of a piano from B to B, or B | A G F E | (E) D C B, which is also known as a modern locrian mode. (In the chromatic and enharmonic genera, each tetrachord consists of a minor third plus two semitones, and a major third plus two quarter-tones, respectively).[3]

[edit]Medieval Mixolydian and Hypomixolydian

Originally used to designate one of the traditional harmoniai of Greek theory, 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.[4] The name Mixolydian came to be applied to one of the eight modes of medieval church music: the seventh mode. This mode does not run from B to B on white notes, as the Greek mode, but was defined in two ways: as the diatonic octave species from G up one octave to the G above, or as a mode whose final was G and whose ambitus runs from the F below the final to the G above, with possible extensions “by licence” up to A above and even down to E below, and in which the note D (the tenor of the corresponding seventh psalm tone) had an important melodic function.[5] This medieval theoretical construction led to the modern use of the term for the natural scale from G to G.

The seventh mode of western church music is an authentic mode based on and encompassing the natural scale from G to G, with the perfect fifth (the D in a G to G scale) as the dominant, reciting note or tenor.

The plagal eighth mode was termed Hypomixolydian (or “lower Mixolydian”) and, like the Mixolydian, was defined in two ways: as the diatonic octave species from D to the D an octave higher, divided at the mode final, G (thus D–E–F–G + G–A–B–C–D); or as a mode with a final of G and an ambitus from C below the final to E above it, in which the note C (the tenor of the corresponding eighth psalm tone) had an important melodic function.[6]

[edit]Modern Mixolydian

Modern Mixolydian scale on G About this sound Play (help·info).

This modern scale has the same series of tones and semitones as the major scale, except the seventh degree is a semitone lower.[1] The Mixolydian mode is sometimes called the dominant scale,[7] because it is the mode built on the fifth degree (the dominant) of the major scale.

The order of tones and semitones in a Mixolydian scale is TTSTTST (T = tone; S = semitone), while the major scale is TTSTTTS. The key signature varies accordingly (it will be the same as that of the major key a fifth below).[1]

Moloch scale is the name used by Klezmer musicians for the Mixolydian scale, with which it is identical. In Klezmer, it is usually transposed to C, where the main chords used are C, F, and G7 (sometimes Gm).[8]
