Review Questions

• How does a Cadential 6/4 chord function in relation to other chords within a harmonic progression?
  • A Cadential 6/4 chord functions as a predominant chord that prepares for the dominant chord in a harmonic progression. It typically appears before a V chord, emphasizing the motion towards resolution. By being built on the IV scale degree in second inversion, it creates tension that enhances the arrival of the dominant, leading smoothly into a perfect cadence.
• Compare and contrast Cadential 6/4 chords with other types of predominant chords, such as predominant seventh chords.
  • While both Cadential 6/4 chords and predominant seventh chords serve similar roles in preparing for the dominant chord, they differ in structure and function. A Cadential 6/4 is specifically a second inversion triad built on the IV scale degree, while predominant seventh chords can take various forms (like ii7) and typically do not resolve directly to the dominant. The Cadential 6/4 often creates a more immediate sense of tension leading into a cadence due to its placement in the progression.
