Tone

The author’s attitude, stated or implied, toward a subject. Some possible attitudes are pessimism, optimism, earnestness, seriousness, bitterness, humorous, and joyful. An author’s tone can be revealed through choice of words and details.

Mood

The climate of feeling in a literary work. The choice of setting, objects, details, images, and words all contribute towards creating a specific mood. For example, an author may create a mood of mystery around a character or setting but may treat that character or setting in an ironic, serious, or humorous tone
