Answer:
The emotional quality of a literary work.
Explanation:
Mood in poetry refers to the poet's choice of words - he or she may use depressing words, uplifting words, neutral words, etc, depending on the mood, or emotions they want to convey. Mood is the general feeling within a poem, the emotions you as a reader may experience while reading the poem.
It doesn't have to be a message about life - while all poems have a particular mood, not all poems speak about life lessons. The attitude of the poet is known as tone, rather than mood. The cause for a character's actions is known as motivation, not mood.
