The basic scales used in western music during the medieval and renaissance were called Mode/church mode.
Church mode, also called ecclesiastical mode, in music, any one of eight scalar arrangements of whole and half tones, derived by medieval theorists, most likely from early Christian vocal convention. The Eastern church was doubtless influenced by ancient Hebrew modal music.
Seven of them were given names that were identical to those used in ancient Greek musical theory: Dorian, Hypodorian, Phrygian, Hypophrygian, Lydian, Hypolydian, and Mixolydian, while the eighth mode's name, Hypomixolydian, was adapted from Greek.
Medieval modes were numbered from 1 to 8, or from 1 to 4 in pairs (authentic/plagal), in which case they were usually named protus (first), deuterus (second), tertius (third), and tetrardus (fourth) (fourth)
