What is the term for a musical passage performed at a slow tempo?

The term for a musical passage performed at a slow tempo is "Adagio." In musical terminology, "Adagio" indicates a relaxed, slower pace, typically suggesting a leisurely or graceful quality to the music. It is often used to evoke a sense of calmness and serenity, making it a popular choice for expressive and lyrical passages.

In contrast, "Allegro" refers to a fast and lively tempo, creating a sense of energy and excitement. "Andante," while slower than Allegro, suggests a moderately slow tempo, akin to a walking pace. "Presto" denotes a very fast tempo, often conveying urgency or briskness. Understanding these terms helps musicians interpret pieces more accurately and convey the intended emotion through performance.
