Remember that the term "Baroque," which we use to label the period before this one, literally means "lumpy" or
"needlessly complex." Obviously, the musicians and artists of the Baroque period weren't calling their own creations lumpy or needlessly complex; those are labels that historians have put on Baroque-era art and music after the fact. This is important to realize because it shows us that the Baroque style was not particularly appreciated by subsequent generations. In fact, many artists, architects, and musicians in the years directly after the Baroque period were self-consciously trying to make a style that was a reaction against the Baroque aesthetic. They were rebelling against the music of their parents and grandparents, which they saw as stuffy, complicated, and terribly busy.
For this assignment, read through Chapter 5 of your text and find three examples of Classical music style being a reaction against the Baroque style. Look for terms like natural, graceful, simple, etc., which should help point you to these discussions in your text.
