What is the meaning of "adagio" in music?

"Adagio" is a term used in music to indicate a slow tempo. It is derived from the Italian word meaning "at ease." When a piece of music is marked as adagio, it suggests that the performer should play it with a relaxed, unhurried feel, allowing for expressiveness and a sense of calm. This contrasts with faster tempo markings, making it important for musicians to understand and interpret the mood and character that adagio conveys.

The other options refer to different tempos and moods in music. Choices that denote moderately fast, very fast, or with excitement describe tempos that have a quicker pace or a livelier feeling than adagio. Thus, the choice of "slow" emphasizes the essence of adagio and aligns with its common use in music notation to create specific expressive qualities.
