The structure of the first chapter can be categorized under the title of a “frame narrative”. A frame narrative can be described as “a literary technique that sometimes serves as a companion piece to a story within a story”. Vonnegut employs this technique by writing in a first person, although he refers to himself as Yon Yonson, and walks the reader through the process of writing the secondary story which is the focus of the novel (chapter 2 onwards). This dynamic is made evident at the end of chapter 1 where Vonnegut writes:
“I’ve finished my war book now . . . It begins like this:
Listen:
Billy Pilgrim has come unstuck in time. “
On the next page, Vonnegut begins chapter 2 with the same lines, indicating that the rest of the novel is the war book that he was referring to initially.
While chapter 1 may not be a part of the core storyline, it does emphasize the theme of time that that may suggest possible foreshadowing by Vonnegut. When the narrator and the two girls cross the Delaware River, the dynamic of reflecting on the passing of time is introduced. Vonnegut states:
“We went to the New York World's Fair, saw with the past had been like, according to the Ford Motor Car Company and Walt Disney, saw what the future would be like, according to General Motors.
And I asked myself about the president: how wide it was, how deep it was, how much was mine to keep. “
Not only does the narrator recognize the past and future, it is suggested that time itself may be a physical concept, one that has width, and depth, one that can be manipulated. Manipulation of time is further explored as the narrator is stuck in a hotel. It is described:
“The time would not pass. Somebody was playing with the clocks, and not only with the electric clocks, but the wind-up kind too. The second hand on my watch what which ones, and the year would pass, and then we switch again. There's nothing I could do about it. As an earthling, I had to believe whatever clocks said — and calendars.
The narrator suggests a lack of control here as he says, “There’s nothing I could do about it”. It’s also stated that somebody was messing with all of the clocks indicating a possible entity that’s responsible for manipulation of time. This is further supported as he refers to himself as an “earthling” implying there are non-earthlings (time controlling aliens?). With the end of chapter 1 and beginning of chapter 2, Vonnegut once again refers to time as he says “Billy Pilgrim has come unstuck in time”. While it is not clear how time will affect the plot of the novel (time controlling aliens might be a bit of a reach), it can be inferred from the first chapter that the manipulation of time will be a greater theme in the development of the book.
