Sub Saharan Africa Music Study Guide

I need the whole study guide finished, which is very easy (will give link to tutor).. and I also need a 150 word response to this question… Most traditional musical traditions in Sub-Saharan Africa reflect the social structure of the people who create it. Societal structure can vary greatly between different ethnic groups. Compare and contrast the social systems of the hierarchical Mande of West Africa and the egalitarian BaMbuti pygmies of the Congo region. How are these different social systems reflected in the musical traditions of the Mande and BaMbuti?
