Dorian mode

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.

[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.

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.

Hit songs in Dorian include, "Evil Ways..., "I Wish"..., "Lowdown"..., "Foxy Lady"..., "Owner of a Lonely Heart"..., "Moondance"..., "Billie Jean"..., and many others.
