Cadential 6/4 chord

Definition

A Cadential 6/4 chord is a specific type of chord used in music that typically resolves to the dominant chord, often occurring at a point of musical cadence. It consists of a triad built on the subdominant scale degree, with the fifth of the triad in the bass, creating a sense of forward motion and preparation for the resolution. This chord enhances the voice leading in harmonic progressions, particularly when dealing with seventh chords, by smoothly transitioning to the dominant and establishing a strong sense of closure.
