Swenson's poem plays upon sound effects in several ways. First and most simply, Swenson repeats words. This creates a pattern, especially when it is read out loud. Second, she uses words like "within" and "think" that share letter groups ("in"), but which do not rhyme. This creates a tension between sound and appearance on the page, much as there is a tension between appearance and reality in the universe. The repetition of the "what" and the "w" sound creates a rhythm—I hear it like a wave meeting the shore—that reassures even though it asks many questions and creates a questioning tone.
