What is the significance of an inauthentic cadence in music theory and how does it differ from an authentic cadence?

An inauthentic cadence in Music Theory is a chord progression that does not create a sense of finality or resolution. It differs from an authentic cadence, which provides a strong sense of closure at the end of a musical phrase. Inauthentic cadences are often used to create tension or uncertainty in a piece of music, while authentic cadences are used to bring a sense of completion and finality.
