I have never heard about any of this information before. Thank you so much for posting it. The idea of slaves not being allowed to speak to each other is so sad. But out of that came something so lovely. I have heard the music before. I used to listen to a "world music" program and I will seek to find something like this again.
I'm glad to read about Andreina Jaramillo passing this music and tradition down to children. It is would be a terrible shame to lose it.
