Actually during my first child my father believed so much in these things that we always had beethoven or something playing in the background, but every time my father wasn't around I'd turn off the music because I felt like it was giving me headaches, seriously.
I do believe that it does help your child's brain to develop and could eventually make your child very smart, but the mother would have to be patient being around that kind of music and hearing it play over and over again because it could get a little tiring after a while.
