What is atmosphere in literature? the attitude of a text toward the subject and theme
the emotional response a text generates from a reader
the author’s opinion of the subject and the audience
the narrator’s perspective in relation to the characters

Atmosphere in literature is the feeling, emotion, or mood that an author creates in a narrative through descriptive language. Though the atmosphere is usually established very quickly in a work of literature, it can change throughout the text depending on the scene or stage of character development.
