Answer:

Explanation:
In "Song of Myself" the poet wanted to highlight something very intimate and profound, something that would be liberating and that would pass that feeling on to the reader in a very literal way. When reading the poem we can see that the poet wanted to implement freedom even in the form in which the poem was written, for this reason, he freed the poem from the formal restrictions of literature and poetic rules, writing freely, without hindrance and without no restriction.
