![]() The flattened seventh of the scale is a tritone away from the mediant ( major-third degree) of the key. As a result, the seventh scale degree is a subtonic, rather than a leading-tone. This scale has the same series of tones and semitones as the major scale, but with a minor seventh. Because of this, the Mixolydian mode is sometimes called the dominant scale. That is, it can be constructed by starting on the fifth scale degree (the dominant) of the major scale. The modern Mixolydian scale is the fifth mode of the major scale ( Ionian mode). 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. 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. This medieval theoretical construction led to the modern use of the term for the natural scale from G to G. 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. The name Mixolydian came to be applied to one of the eight modes of medieval church music: the seventh mode. 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. 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. Four centuries later, Boethius interpreted Ptolemy in Latin, still with the meaning of transposition keys, not scales. It was appropriated later (along with six other names) by 2nd-century theorist Ptolemy to designate his seven tonoi or transposition keys. The term Mixolydian was originally used to designate one of the traditional harmoniai of Greek theory. This diatonic genus of the scale is roughly the equivalent of playing all the white notes of a piano from B to B, which is also known as modern Locrian mode.Īudio playback is not supported in your browser. In the diatonic genus, a whole tone ( paramese to mese) followed by two conjunct inverted Lydian tetrachords (each being two whole tones followed by a semitone descending). In its diatonic genus, this is a scale descending from paramese to hypate hypaton. In Greek theory, the Mixolydian tonos (the term "mode" is a later Latin term) employs a scale (or " octave species") corresponding to the Greek Hypolydian mode inverted. The prefix mixo- (μιξο-) means "half", referring to its resemblance to the Lydian mode. However, what the ancient Greeks thought of as Mixolydian is very different from the modern interpretation of the mode. The invention of the ancient Greek Mixolydian mode was attributed to Sappho, the 7th-century-B.C. ![]() ![]() The idea of a Mixolydian mode comes from the music theory of ancient Greece. The modern diatonic mode is the scale forming the basis of both the rising and falling forms of Harikambhoji in Carnatic music, the classical music form of southern India.
