Diction: Creates a rhythmic diction by rhyming every other line. He uses indirect characterization and is able to through his diction. The author didn't use extremely advanced diction but it was very proper. What made his diction stand out is the way he put his words together.
Shift: Shift occurs in last paragraph. His diction becomes bland and begins to talk more about those watching him and what they are doing rather than Richard Cory and what he was doing. After the shift author used understatement when he says Richard Cory kills himself.
Tone: The tone of Richard Cory is created by the authors diction. I feel that the tone is quietly observant. It seems to be written from an outside point of view, somebody or a group of people who has been watching Richard Cory.
