In musical terms, which of the following indicates a spirited style?

The term "Spiritoso" is used in music to describe a lively, spirited, and energetic style of playing or performing. It suggests that the music should be executed with vigor and enthusiasm, often conveying a sense of joy or excitement. This instruction encourages musicians to infuse their performance with an animated character, aligning closely with the concept of spiritedness.

Other musical terms also have specific meanings that differentiate them from "Spiritoso." For instance, "Espressivo" refers to playing expressively, emphasizing emotion rather than spirited energy. "Leggiero," on the other hand, indicates a light and delicate manner of playing, focusing on clarity rather than vigor. Finally, "Rubato" is a technique involving the flexible manipulation of rhythm for expressive purposes, which is not necessarily related to a spirited approach.
