Narrative structure refers to the organized way in which a story is presented, encompassing elements such as the plot, characters, and setting that work together to convey the intended message or theme. In the context of opening statements, narrative structure is crucial as it sets the stage for the case, captures the jury's attention, and establishes a framework for understanding the evidence that will be presented. A compelling narrative structure not only engages the audience but also helps to build credibility and persuasion.
