Walt Whitman is often referred to as 'the father of free verse', since he abandons traditional metric patterns in his works. The poem '<em>Song of Myself' </em>explores the freedom of being one's true self, and free verse strengthens the speaker's individuality and liberty. It helps the author present the wandering nature of a speaker.Whitman also uses free verse as a means to connect to his audience and establish a friendly, conversational tone.
