Rhetoric refers to the art of persuasion. A rhetorical essay is a type of essay which is less concerned about what writers say than how he says. Similar to other essays, it incorporates all parts like the introduction body and a summary. However, the main purpose is to appeal to the audience with skills of writing. In a rhetorical analysis essay, the writer focuses on explaining why. For instance, why did the writer use pop music or calm music, Or why did he choose bright colours. Hence, the language plays a key role here.
