An authentic cadence that does not meet the requirements of a perfect authentic cadence (PAC) is known as what?

Correct answer: An imperfect authentic cadence (IAC).

Explanation

The category of authentic cadences (V-I) is divided into two main types: perfect and imperfect. A perfect authentic cadence (PAC) is the strongest and most final-sounding type, with strict rules. Any authentic cadence that deviates from these rules (e.g., has an inverted chord or a different soprano note over the tonic) falls into the broader category of an imperfect authentic cadence (IAC).
