Explanation:

Analyze the aesthetic shift from Baroque to Classical

Using the Classical Era Aesthetics knowledge point, we examine how musical structure reflects emotional expression. While Baroque music typically relies on a single affect (emotion) per movement, Classical era music embraces dramatic contrast within a single movement.

Evaluate thematic contrast in sonata form

Using the Sonata Form Contrast and Thematic Contrast knowledge points

$$ \text{Baroque: One Theme} ightarrow \text{One Affect} $$

$$ \text{Classical: Multiple Themes} ightarrow \text{Contrasting Emotions} $$

Classical composers use different themes (such as a dramatic first theme and a lyrical second theme) specifically to convey contrasting emotions within the same movement. This directly supports the third option.

Answer:

• the same theme to convey a single emotion
• the same theme in different ways to convey contrasting emotions
• different themes to convey contrasting emotions (Correct answer)
• different themes to convey the same emotion
