#1 PEASANT makes good points in second post, but my defense of Burns' perspective stands. Traditional Indian classicism includes considerable improvisation, with melodic variations on raga chord progressions. Did they inspire the Irish? Muslim muezzins ad-lib vocally on recitations, sometimes for hours on end. Did Dravidians invent jazz? Did they cakewalk in Damascus? Or did separate peoples draw similar conclusions about the potential of musical creativity? Despite the strained possibilities of cross-pollination, I thinks the primary bloodline of this particular musical expression "jazz" is being presented fairly in this program so far. Burns still has 16 hours to go, after all. It is no "blackwash" to acknowledge these primary sources.
