Which tempo marking corresponds to a quarter note equals 120 in common time?

The correct answer, which notes a tempo marking that corresponds to a quarter note equaling 120 in common time, is Allegro. This term signifies a lively, fast tempo, generally considered to fall within the range of about 120 to 168 beats per minute. When a composer indicates a tempo of quarter note equals 120, it indicates a brisk pace that aligns perfectly with the definition of Allegro.

In comparison to other tempo markings, Andante typically represents a moderate walking pace, which generally ranges from about 76 to 108 beats per minute, making it slower than Allegro. Largo denotes a very slow tempo, often considered a serene pace, typically around 40 to 60 beats per minute. Adagio is also a slower tempo than Allegro, falling in the range of about 66 to 76 beats per minute. Thus, Allegro is the appropriate term that reflects the faster pace of 120 beats per minute, distinguishing it from the other, slower tempo markings.
