There was a wonderful folk song combo back in the 40s-70s called Marais and Miranda who sang folksongs from around the world. One of the songs of theirs I came across recently was "Umbira Melody." It's about a man playing an intrument called an mbira (the title's an alternate spelling). Although the liner notes only mention the song as "African" I think it can be narrowed down a little more to Zimbabwe.
In any case, this was painted to the feel of the song.
