Which term means 'with vigor or spirit'?

The term that means 'with vigor or spirit' is "con brio." This Italian phrase is often used in musical directions to indicate that the performer should play in a lively and energetic manner, infusing the music with enthusiasm and dynamism.

The choice of "con brio" highlights the importance of expressing the vivacity in the performance, pushing musicians to bring a sense of excitement to their interpretation. In contrast, while "con fuoco" also connotes a spirited performance, it specifically emphasizes playing with fire or passion, which is slightly different from the general vigor implied by "con brio." "Animato" suggests playing in a spirited or animated way but does not necessarily imply the same level of energy and vigor as "con brio." On the other hand, "cantabile" refers to a smooth and lyrical style, focusing more on expressiveness rather than lively vigor. Therefore, "con brio" is the most precise term for playing with vigor or spirit.
