That's amazing, Karen. It certainly puts a whole new spin on cultural hearths and the "tipping point." You know this stuff is all so far outside my understanding ;-), but there was a piece on Good Morning America a few days back about how each person's brainwaves can be interpreted into music and that each person's music is different--it seems like that might be a very, very, very early form of picking up on some of this. Anyway, this makes great food for thought for the weekend! Jes
