Which term indicates a spirited manner of playing?

The term that indicates a spirited manner of playing is "spiritoso." This musical directive invites performers to play with energy, enthusiasm, and liveliness, infusing the music with a vibrant and animated character. When you see "spiritoso" in a musical score, it suggests that the passage should be played with a sense of joy and vigor, enhancing the expressive quality of the performance.

Other terms such as "allegro" also denote a lively tempo, but it specifically refers to the speed of the piece rather than the spirited nature of the playing. "Staccato" indicates a style of playing where notes are detached and played sharply rather than smoothly connected. "A tempo" refers to returning to the original speed of the piece after a deviation. While all these terms relate to performance, "spiritoso" uniquely highlights the vivacious and spirited approach to interpretation.
