One of the most important 20th century singers of South African popular music was Miriam Makeba, who played a key-role, in the 60s, in drawing global audience's attention to African music and its meaning. Zenzile Miriam Makeba was said to have been one of the most influential and popular musicians of Africa, beginning in the 1950s. She was a part of three bands, including one all-woman band and two others. She performed all types of jazz music, traditional African music, and music that was popular in Western Africa at the time. Miriam played a majority of her music in the form of "mbube", which was "a style of vocal harmony which drew on American jazz, ragtime, and Anglican church hymns, as well as indigenous styles of music." After she moved to the U.S., problems with Makeba's passport occurred and she had to stay in America, it was said that she put an American twist on most of her African music. She had a very diverse scale of her vocal range and could hit almost any note. "The Empress of African Music" died at the age of 76.
