What is "negermusik"

Negermusik ("Negro Music") was a pejorative term used by the Nazis during the Third Reich to signify musical styles and performances by African-Americans that were of the Jazz and Swing music genres. They viewed these musical styles in a racist fashion as inferior works belonging to an "inferior race" and therefore prohibited. The term, at that same time, was also applied to indigenous music styles of black Africans.
