thanks
The first Africans transported to this country came from a variety of ethnic groups with a long history of distinct and cultivated musical traditions. Some were able to bring musical instruments with them or build new ones in this country.
As well as bringing harmonic and rhythmic features from western and sub-Saharan Africa into European musical styles, it was the historical condition of chattel slavery experienced by black Americans within American society that contributed the conditions which would define their music. Many of the characteristic musical forms that define African-American music have historical precedents.
Thank you so much ^^
