What distinguishes an aria from a recitative?

An aria is characterized as a solo vocal piece that typically expresses deep emotion and showcases the singer's vocal talent. It is often more structured and melodic compared to recitative. Arias allow for elaboration on themes or emotions, providing a moment of reflection or expressing a character's feelings in operatic and other vocal performances.

Recitative, on the other hand, is more speech-like, often used to advance the plot or dialogue in an opera. It tends to have a much freer rhythm and is less focused on melodic expression, serving as a bridge between the more lyrical arias and the spoken dialogue.

The distinction in form and purpose—where the aria emphasizes emotional expression and technical prowess—highlights why this choice is the correct one. Because of this focus on emotional depth and musicality in arias, they stand out distinctly from the more narrative-driven recitative.
