Answer: Authors use tone to differentiate scenes between viewpoint characters. So while Irving's attitude is whiney, Pete's can be overbearing. Use word choices and the unique events and story elements that each character focuses on to play up the different tones. Mood is what the reader feels while reading a scene or story.
Mood and tone are two literary elements that help create the main idea of a story. The mood is the atmosphere of the story, and the tone is the author's attitude towards the topic. By doing so, it will help us find meaning in the story or passage and help us feel more connected to the writing.
