How does understanding the audience impact a writer's tone?

Understanding the audience significantly impacts a writer's tone because it enables the writer to choose a tone that resonates with that specific group of readers. When a writer knows who their audience is, they can tailor their language, style, and emotional appeal to match the audience's expectations, values, and interests. For example, a piece intended for teenagers may use informal language and a light-hearted tone, while a report for a board of directors would require a formal and straightforward tone. This alignment enhances the effectiveness of the communication because it engages the audience, making them more likely to connect with and understand the message being conveyed.
