The poem is presented in thirty-four lines of free verse divided into couplets and singlets, mostly couplets. The singlets tend to be shorter and used perhaps for emphasis.
Parentheses are used twice: once within a line, and once bracketing a singlet. The reason for their use is not clear, as the bracketed portions do not come across as asides or really any different from the non-bracketed portions.
The title summarizes the theme nicely and is a kind of short form poem in itself. Ironically, Ezra Pound, whom Schwartz quotes, probably would have edited out the entire rest of the poem.
