Which term denotes a fast pace in music?

The term "Allegro" is used in music to indicate a lively and fast tempo. It originates from the Italian word meaning "joyful" or "merry," and it typically suggests a pace that is cheerful and brisk, usually ranging around 120 to 168 beats per minute. This term is widely recognized among musicians and is an essential part of musical notation, guiding performers on the intended speed of a composition.

In contrast, the other terms have different meanings related to musical pace. "Andante" refers to a moderately slow tempo, often translating to a walking pace. "Rubato" denotes a flexible tempo, allowing for expressive timing but does not imply a specific fast pace. "Prestissimo" indicates an extremely fast tempo, even faster than "Allegro," and can be seen as bordering on the maximum speed a piece may be played, making "Allegro" the most accurate term for denoting a fast pace.
