What term is used to describe a musical passage performed with brilliance?

The term "con brio" is used to describe a musical passage performed with brilliance and vigor. This Italian phrase translates directly to "with spirit" or "with brilliance," indicating a lively and energetic performance style. Musicians use this term to invoke a sense of excitement and dynamic intensity, prompting them to play with enthusiasm and flair.

In contrast, "con moto" refers to a tempo that is lively or with movement, but it does not specifically emphasize brilliance. "Doloroso" translates to "sorrowful" and conveys a sense of sadness, which is not aligned with the idea of brilliance. "Marcato" means marked or accented, but it mainly refers to the emphasis placed on certain notes, rather than the overall brilliant execution of a passage. Thus, "con brio" is the most fitting choice for describing a passage that is intended to be performed with brilliance.
