What is the tempo associated with the term "Allegro"?

The term "Allegro" is indeed associated with a fast, quick tempo. In musical terminology, "Allegro" typically indicates a lively and brisk pace, often suggesting a sense of energy and excitement. This tempo is commonly characterized by a beats-per-minute range of around 120 to 168, which is significantly faster than moderate or slow tempos.

The other terms refer to different styles of tempo. The broad and slow designation points towards terms like "Andante" or "Largo," which indicate a more relaxed speed. Moderate and comfortable would relate to "Moderato," a tempo that is neither fast nor slow. Finally, "In a walking manner" corresponds to "Andante," a tempo that resembles a walking pace. Therefore, "Allegro" specifically conveys that faster tempo, making it the correct answer.
