ELEVENTH BIENNIAL INTERNATIONAL CONFERENCE ON BAROQUE MUSIC

Le deuterus et la genèse du mode mineur at XVIIe siècle
Because of the unusual place of the semitone between the first and the second degree, the tetrachord of the deuterus could not be used in the modern minor scale without sharpening its second degree. Therefore the Phrygian tetrachord was transformed into a Dorian one. The use of accidentals in polyphonic music contributed to destroy the properties of the early modes, to fuse them together and to give birth progressively to the minor key.
