What is "mixolydian mode"

Mixolydian mode \Mix`o*lyd"i*an mode`\ [Gr. ? a mixing + E. Lydian.] (Mus.) The seventh ecclesiastical mode, whose scale commences on G.

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 or scale; one of the medieval church modes; a modern musical mode or diatonic scale, related to the medieval mode. (The Hypomixolydian mode of medieval music, by contrast, has no modern counterpart.)

This mode is known as Harikambhoji in Carnatic music, the classical music form of southern India.
