The pair of lines from the passage that contains a change in intonation is "Well, son, I'll tell you. Life for me ain't been no crystal stair. It's had tacks in it. And splinters. And boards torn up." The change in intonation is evident in the transition from a more conversational tone in the first line to a more descriptive and broken-up delivery in the subsequent lines.
