This section of the paper should be the result of your careful analysis of the work. By analysis here, I don’t mean a Roman numeral chord analysis or detailed analysis of the form, although you might certainly want to talk about harmony and form. Rather, think of this paper as if you were explaining the work to someone else.
What do you find most compelling about how the music works? Where does Bach surprise the listener? In what other ways does the work conform to expectations of the genre? If the work is texted, how does the music highlight and/or interpret the text? Remember, this is intended to be a program note, written for a musically knowledgeable audience . So….what should the audience member listen for?
