Which term would you use to describe a spirited or lively performance?

The term that best describes a spirited or lively performance is "vivace." In musical terminology, "vivace" indicates a lively and brisk tempo, which conveys an energetic character in the performance. It is often associated with a sense of joy and a vibrant feel.

On the other hand, "allegro" also denotes a fast tempo, but it leans more towards being cheerful rather than spirited. "Spiritoso," while suggesting a lively or spirited approach, is not as commonly used or as specific in its definition of tempo as "vivace." "Andante," which means a moderate tempo, indicates a laid-back and gentle pace, making it unsuitable for describing something spirited or lively.

Therefore, "vivace" is the most appropriate term to accurately convey the essence of a spirited or lively performance.
