Chapter One, Cycle of Time

I realized after reading about "The Lumberjack Song" in chapter one that Vonnegut may use the structure of the song to model his novel.  The song begins as any other song but ends with the first line again.  This peculiar structure creates an ongoing song that will not stop.  The song is a cycle which may model the structure of the novel later.  Vonnegut cannot get a firm grip on every memory of Dresden and uses this structure to get the stories from his head into novel form.
