There is no real definition for fado, the languid, darkly passionate blues-like folk and popular music form Portugal has so generously given the rest of the world. But when Mariza, the Portuguese star of this genre, speaks generally about what she does as a musician, you can read between the lines and get a very good approximation of what fado means to her.
"Perfect music doesn't exist," she said. "But I want to be perfect. When I am onstage, I use everything, everything I have. I open my Pandora's box and I take out all of my feelings, because [fado] is a music that draws upon all the feelings of a human being - doubt, jealousy, longing, fate, destiny, joy, happiness, passion, love, lost love - everything that is part of life is included inside of this music."
