Which genre is characterized by a rhythmic structure and sometimes humorous content?

The genre characterized by a rhythmic structure and often humorous content is the limerick. Limericks are a specific form of poetry known for their distinct AABBA rhyme scheme and a specific metrical pattern, which gives them a playful and rhythmic quality. Their brevity and structural constraints lend themselves to humorous or whimsical themes, often featuring absurd situations or clever wordplay.

In contrast, the other genres listed, such as epic, tragedy, and epic poem, typically focus on more serious themes and narrative content, often exploring grand human experiences or moral dilemmas. They do not share the same light-hearted or entertaining approach that limericks embody.
