I’m reading a book on music by Jocelyn Godwin in which the author examines ancient musical charms. These charms consisted of a series of six or seven vowels that each represented a god. Godwin claims that such charms were throughout the ancient world as wards or guards against evil and existed in amulets as well as chanted songs in religious rites. One such example, Godwin points out, exists in the Bacchic exclamation EVOHE! Another is in the name of the Jewish God, YHVH, whose power was so great as to necessitate a ban on the pronunciation of his name. Thus the Jews added the other name of the god, Adonai, or Lord to YHVH to create YaHoVaH, or Jehovah. This seven syllable chant of vowels constituted one of the greatest religious music charms available in the Jewish world. My question is, driven by intuitive insight, is the Christian Euouae at the end of a chant a similar charm? I know that the Euouae is a shortened bit for Seculorum, Amen, but why choose that phrase, unless the amulet phrase existed prior? In other words, is there a vestigial remnant of this ancient musical magic embedded in the Gregorian “Seculorum, Amen” phrase of Euouae? By extension, is Gregorian chant itself an extended form of this same type of musical magic, the words being fitted to conjure certain metaphysical powers?
