With vigor or spirit (with brilliance).

• A. Con
• B. Con Fuoco
• C. Con Brio
• D. Crescendo

Answer: (C)

Con Brio conveys playing with vigor and spirited energy, a bright, lively character. It guides you to infuse the music with bounce and life—focused, buoyant, and energetic—without necessarily pushing to extreme loudness. That mood matches the idea of “with vigor or spirit (with brilliance)” most directly. Compared to Con Fuoco, which adds a fierier, more intense edge, Con Brio keeps the energy lively and articulate without becoming aggressively fiery. Crescendo isn’t about character at all—it’s a gradual increase in volume over a passage, not a directive about how the music should feel. And a simple Con by itself isn’t a full character marking. So Con Brio is the best fit for this description, guiding you to a spirited, bright performance.
