A Mixolydian "Yankee Doodle"
General mountain dulcimer or music discussions
It's funny, setting the speed aside, the Mixolydian version sounds pretty musical to me.Bronson was suggesting this as a general experiment in mode shifts, and I don't mean it to apply principally to dulcimers and the sixth-fret issue, though of course that issue arises incidentally.Bronson would have agreed with you that for the modern ear, substituting a flatted 7th "just doesn't work", but he suggests that this wasn't always the case.In the same chapter (of
The Ballad as Song) he looks at six versions of "Henry Martin". I'll simplify it to five versions to shorten the explanation:Ionian (natural 7th)Ionian/Mixolydian hexatonic (missing 7th)Mixolydian (flatted 7th)Dorian (flatted 3rd)Dorian/Aeolian hexatonic (missing 6th)All were collected between 1904 and 1908. Four are from England and one from Minnesota.Bronson makes the case that this pattern of variation is pretty common. One point he makes is that when you see a tune with Ionian and Dorian versions, you very often find Io/Mixo and Mixolydian versions as well. It's as though the tune changed one step at time by dropping, adding, sharpening, or flatting a single tone. Tunes are seldom seen to make a two-or-three step jump without leaving intermediate forms behind.Another point he makes is that these changes may have sounded more musically acceptable than they do today. (Much as we would regard a V-I and a V7-I cadence as being somewhat interchangeable. Though they are different, one is not perceived as more or less musical than the other.)So that, I believe, was why Bronson suggested the exercise.
The Ballad as Song a great book, BTW, though it's tough slogging in spots.Out of print, unfortunately, but there's always interlibrary loan.
