What has worked well from my experience for a mod C introduction is a clear thesis statement, which is then related to the question. followed by a sentence or two relating the two texts to the thesis. Then simply relate the thesis and texts to the question.
For example; "How is the nature of conflicting perspectives revealed through the actions of a composer? In your answer refer to [main text] and at least one supplementary text."
Thesis statement: Conflicting perspectives result from different interperetations of the same facts.
Relate to question: Through the actions of their composers, texts reflect the inherent bias evident from an individual's inteperetation.
Texts: Text 1, by author of text 1, explores the connotations of something or other [Haven't read JC, so I'd have no idea what to do here], while text 2 presents a representation of [other stuff, themes perhaps?], reflecting the impact of conflicting perspectives on an individual's opinion.
Of course, you'll need to edit it to make it flowy etc.
If you're OK with your body but not the intro, what I'd reccomend is writing the body of the essay before hand, with a skeleton intro, then going back and re-writing your intro, to make sure you have covered all the points in your essay.
Also, I'd seriously reccommend getting another sup-text besides TYFS, something that expresses composer bias and other, less 'meta' examples of conflicting perspectives.
