Plagal Progressions

Definition

Plagal progressions refer to a harmonic movement that typically moves from the subdominant chord (IV) to the tonic chord (I), creating a sense of resolution. Often characterized by their use in hymns and church music, these progressions provide a softer and more subdued return to the tonic compared to the stronger dominant to tonic resolutions. They are a vital part of understanding how chords connect in root position, influencing both melodic direction and emotional impact in music composition.
