Meine Seele erhebt den Herren (My soul magnifies the Lord) is Martin Luther's translation of the Magnificat canticle. It is traditionally sung to a German variant of the tonus peregrinus, a rather exceptional psalm tone in Gregorian chant.[1] The tonus peregrinus (or ninth tone) is associated with the ninth mode or Aeolian mode.[2] For the traditional setting of Luther's German Magnificat that is the minor mode for which the last note of the melodic formula is the tonic, a fifth below its opening note.
