What is the poet's tone in the poem, The Moon and the Yew Tree?

Much of the language in the poem conveys alienation by employing language to generate estrangement. The first four lines of the second stanza exemplify this uneven and fluctuating tonality: “The moon is no door. It is a face in its own right, / White as a knuckle and terribly upset. / It drags the sea after it like a dark crime; it is quiet / With the O-gape of complete despair. I live here” (8-11). The author oscillates between a detached tone of objective observation, oftentimes melancholic, and a more melodramatic tone of personal revelation. The first two lines of the poem exemplify the former tonal tendency: “This is the light of the mind, cold and planetary / The trees of the mind are black. The light is blue” (1-2); the final, pleading line of the first stanza the latter tonal tendency: “I simply cannot see where there is to get to” (7).
