Keep your book. The poem may suggest either one combined attitude, or distinctive attitudes, one toward the matter of the poem and the other toward the audience of the poem. We have the most trouble with mood and tone when we encounter poets who use irony. You will find the introductory sections of your anthology useful for the latter task. But then, sometimes, slinging the terms around helps you to come to understanding.
Subsequent paragraphs follow through, explaining the development of the poem in detail.
Professor Sharp points out to me that he always knows a paper won't rise above a C when a student begins by announcing that Shakespeare is a great writer or a great dramatist. If you feel the need to begin a paper this way, then you have not finished the process of reading and thinking that precedes the writing of a good paper. You will find that Professor Sharp recommends adapting the tried and true strategies of rhetoric to the writing of critical essays.
