What is the name of the cadence that sounds finished, moving from dominant to tonic chords?

The name of the cadence that sounds finished and involves a movement from the dominant chord to the tonic chord is known as the Perfect Cadence. This type of cadence is characterized by its strong sense of resolution, which is why it is often used at the end of phrases or sections in music to create a feeling of completeness. In terms of harmony, the dominant chord (V) leads directly to the tonic chord (I), establishing a finality that is pleasing to the ear.

In contrast to other cadence types, the Perfect Cadence is specifically recognized for this progression. For instance, the Imperfect Cadence typically ends on the dominant chord and does not provide the same sense of closure. The Plagal Cadence, often referred to as the "Amen Cadence," involves a movement from the subdominant chord to the tonic, which conveys a different emotional quality. The Interrupted Cadence creates an unexpected interruption by leading from the dominant to a different chord (often the relative minor), leaving the listener in suspense rather than a feeling of completion. Therefore, the definition and function of the Perfect Cadence align perfectly with the movement from dominant to tonic, making it the correct answer.
