Seed--I was looking for something that goes through from B7 in the "A" part of the song--I think I found something--which I believe is the "Carousel Waltx" only thing is that it seems to work better with the substitute chords--

Pete--You give the impression that the scales were developed in the time period that you mention--they were much older--even diatonic music, using scales instead of modes, was much earlier--the music of the time preceding the development of "even temperament" wasn't microtonal, the difference was that the scales had perfect intervals in them--and you had to re-tune the instruments in order to change keys--

My recollection is that the kind of diatonic melodies that we commonly find in British Isles and American folk music tended to show up in composed music around this time--
