diegesis, "diegetic" sounds

Although veteran Hollywood composer Franz Waxman is credited with the score for the film, his contributions were limited to the opening and closing titles and the piano tune ("Lisa") written by one of the neighbors, a composer (Ross Bagdasarian), during the film. This was Waxman's final score for Hitchcock. The director used primarily "diegetic" sounds—sounds arising from the normal life of the characters—throughout the film.^[4]
