How would 'con brio' most likely affect the tempo of a performance?

The term 'con brio' is an Italian musical directive that translates to 'with vigor' or 'with spirit.' This instruction is intended to infuse a performance with energy and enthusiasm, encouraging musicians to play in a lively manner. When a piece is marked 'con brio,' performers are guided to interpret the music with briskness and an animated character, which directly influences the tempo by usually suggesting a quicker pace or a more vigorous approach.

This understanding of tempo is essential, as it sets the mood for the listeners and enhances the expressiveness of the music. In contrast, other choices imply a slowing down, a quiet performance, or a solemn manner, which are not aligned with the lively and spirited interpretation that 'con brio' demands.
