In My Papa's Waltz by Theodore Roethke, how can the tone be described, which words reflect this tone, and how does it add to the overall meaning of the poem?

Roethke's "My Papa's Waltz" is about a relationship between a father and his son. Beginning with the title, the author's meticulous choice of vocabulary paints an image of a dance. Continuing on, the first stanza begins the recollection of the waltz and sets the tone. At first glance an abusive tone is observed. Specifically, the reference to "whiskey on [his] breath," the dizziness felt, and his recollection of hanging on to his father "like death" (Line 1-3). It is in the second stanza that the tone shifts and the dance becomes more disorderly. As images of playfulness and teasing are seen the third stanza, shifts the tone yet again. Constant changes between verses often results in misinterpretation. Similar to the first stanza, a rough manner is noted as we read words such as "held," "battered," and "scraped" (Lines 9-12). While a reader may hastily assume the worst, it is important to consider all contributing factors. In looking at Roethke's background we note the bond he shared with his father growing up. Finally, the last stanza sees a "palm caked hard by dirt" which is a suggestion to his father's greenhouse. Growing up, Roethke enjoyed spending time playing and working in the conservatory with his dad. Furthermore, the image produced by the last two lines of a small boy clinging tightly to his father's shirt provides a demonstration of the love shared in their relationship.
