Zimbabwean singer Chiwoniso has been playing the mbira, a thumb piano, since the age of four. The Shona people of Zimbabwe have used the mbira in religious ceremonies for thousands of years, but during that time it was only played by men. Chiwonisa is helping to change that.

Our guide to global music, Ish Mafundikwa, talks with the World Vision Report's Leda Hartman about Chiwonisa and her new album, "Rebel Woman."
