This us to draw meaning out of

This excerpt of the story of Hamlet is clearly shifting throughout the process of his speech as he begins with a determined and a bit inspirational tone, but shifts into one of bloodlust and a very angry and vengeful one as he begins to desire the worst for the person who murdered his father. The shift in tone can be most clearly seen when he talks about base matter and when he yells out by heaven, signaling to the reader that his transformation into an insane person out for revenge has been fully completed and has replaced the old calculating Hamlet. The shift in tone allows us to draw meaning out of the soliloquy.
