Hey ubu, I was glad to see you rose to the occasion with the scales discussion. I ain't no music theorist. I must compliment you on wonderful way you share your knowledge with others. Not necessarily concise but most definitely clear. Attaboy! In your elucidation of scales you indicated that the Roman rites were responsible for Greek modal nomenclature. Am I correct in assuming the Greeks of the Hellenic and Helenistic Ages derived their music theory from the Pythagoreans and similar Sophist movements or where they derived from the Mystery Cults? The Eleusinian Mysteries (sic) IIRC were associated with Orpheus. Maybe both!
