What is the author's tone in Pineapples and Pomegranates by Paul Muldoon?

Muldoon also makes the poem cohere by repeating certain words, such as "munificence" in lines 8 and 9, "hand" in lines 10 and 12, and "right?" in lines 9 and 14. Although these repetitions create a tone of doubt, they also hold together disparate ideas, creating a sense of wholeness in the face of uncertainty.
