Hypodorian mode

This was the plagal mode corresponding to the authentic Dorian, and was called the Hypodorian mode.

The author, Abraham Ḥazan, a cantor born in Thessaloniki in 1533, probably also composed the melody, which is in the hypodorian mode.

The Hypodorian mode, a musical term literally meaning 'below Dorian', derives its name from a tonos or octave species of ancient Greece which, in its diatonic genus, is built from a tetrachord consisting (in rising direction) of a semitone followed by two whole tones.
