Interesting post, PoppaGator. I think maybe I am a bit of a hybrid when it comes to your categories though. I was inspired to learn to play accordion by someone from Belgium who showed up at one of the jam sessions I was attending. He played in a continental European style, and I was smitten. I'll bet there were many experiences very similar to mine back in the 1800s and early 1900s, for instance, when immigrants to various countries in North and South America (or captive peoples brought to those places) shared the music of their home countries and their people with the other peoples they encountered in their new homes. And I'll bet that this sort of cross-pollenation of cultures is a big part of what gave rise to some of the traditional musical genres in countries in North America and South America, like the blues, for instance.
