What is Plagal Cadence?
A plagal cadence is a type of chord progression that moves from the subdominant chord (IV) to the tonic chord (I). This cadence creates a gentle and smooth sense of resolution rather than the strong tension-and-release found in a dominant-to-tonic cadence. Because of its softer sound, it often feels calm and reassuring.
For example, in the key of C major, a plagal cadence would involve the chord F major (the subdominant) resolving to C major (the tonic). This movement is sometimes called the “Amen cadence” because it frequently appears at the end of hymns where the word “Amen” is sung.
Plagal cadences are used in many musical styles, including classical music, church music, gospel, and modern pop. They are often used to provide a peaceful or reflective ending to a phrase or section. While they do not create as strong a sense of finality as a dominant cadence, they still provide a clear and satisfying resolution.
