I think you mean "Ebony and Ivory," Sergio. Ebony is a type of wood that is very dark -- used for the chromatic keys on the piano. Of course the "white" keys aren't ivory these days, but presumably at one time they were ivory clad.

I just can't like Stevie Wonder, no matter how hard I try. I must be lacking a gene or something. I realize he's very talented in both performing and writing, and all that. But his most interesting song, to me, is "Just Enough for the City" or whatever the proper title of that one is.
