Rok, in order to understand my specific comments in regard to Africa, the berimbau, and capoeria, we have to focus on the history of "Bahia"; but first, I would like to respond to some of Frogman's comments that are related.
There is no doubt that many different kinds of rhythms, and drumming that existed in Africa, no longer exist there, but can be found in other places. How is this possible?
Before slavery, Africans were living all over the continent in villages, if they lived far away from powerful countries and tribes, they lived in peace; but when slavery put a price on African heads, powerful countries, and tribes captured and sold them. Different villages had different drumming and rhythms, they were exported west, first to Cuba, which was "the board of trade" for slaves, and then to wherever their final destination was to be. Things that were unique to many villages, no longer exist on the continent of Africa, but they can be found where those slaves final destination was to be.
For my specific comments, we have to focus on the history of "Bahia". It was a center of sugar cultivation; integral to this was the importation of a vast number of slaves; more than 37% of all slaves taken from Africa were sent to Brazil, and processed in Bahia, and that's another reason for the unique rhythms that can be found in Bahia, but not in Africa. I don't mean for this to be a diversion, our focus is still on Cuban music.
Enjoy the music.
