Composed by Hans Zimmer and James Newton Howard, The Dark Knight soundtrack is a dark, atmospheric blend of orchestral, electronic, and minimalist music. It uses driving rhythms, unsettling textures, and recurring motifs to represent characters like Batman and the Joker. The score heightens the film’s tension and psychological depth, with standout tracks like "Why So Serious?", which features experimental techniques to evoke the Joker’s instability, and "Like a Dog Chasing Cars," which underscores the action and emotional stakes of the story.
