Is this about Jazz or Just music in general? My comments were made thinking it was about Jazz.
As far as the Music part of this slavery stuff, there are many things to consider, such as:
And this applies to Brazil, Cuba and the USA.
Dominate Religion, Form of Government, Geographical location, climate, size of country, what was the economy based on, population size and ethnicity, and Political status of the area.
all of these things will shape the people, their relationships with each other and the art the create.
Folks in the USA had musical instruments to play. Violins (fiddles), guitars, pianos etc... Fife and Drum units were very big in North Mississippi. Maybe the folks in Cuba, and esp Brazil, only had drums (logs?) to beat.
The relationship between slaves and whites in the US was much different than those relationships in Brazil or Cuba. This fact shaped everything!
I could go on, but you get my point.
BTW, there are more black folks in Brazil than any other country except Nigeria. If you go to Brazil during 'Carnival', you will see them. Any other time, maybe not.
The Spanish came to the New World Looking for Gold. The English came looking for God. That explains a lot.
You may be trying to merge apples with oranges.
