Don`t get your spouse to try to teach you a musical instrument. It`s just a terrible idea," she said The 29-year-old actress claimed that she does not know anything about music and has to concentrate on songs to be interested in them. "I never really listen to it music. If it`s on in a room, I can`t really hear it. I don`t have that sort of brain. And that`s another reason I was so interested in doing this film," Knightley said.
