Final answer:
Lyrics, odes, and epics are genres within the literary form of poetry, which includes various styles and differences in medium, objects, and manner of imitation.
Step-by-step explanation:
Lyrics, odes, and epics are genres of the literary form known as poetry. Poetry is one of the four major genres in literature, which also include drama, fiction, and creative nonfiction. These poetic forms differ in medium, objects, and the manner of imitation, as described by Aristotle and exemplified through works like Homer's The Iliad and The Odyssey. Epic poetry, such as the works of Homer, combines elements of story narrative with the artistic expression typically found in poems and often revolves around heroic figures and grand themes. On the other hand, lyrics are typically shorter and express personal emotions, while odes are formal and celebratory, focusing on specific subjects or occasions.
