Review Questions

• How does a half cadence create tension within a musical phrase?
  • A half cadence creates tension by ending on the dominant chord, which leaves the listener expecting further resolution. This unresolved feeling compels the music to continue rather than conclude, making it an effective tool for composers. By using predominant chords before reaching the dominant, the structure amplifies this sense of anticipation and pushes the music forward.
• Compare and contrast half cadences with authentic cadences in terms of their functional roles in musical composition.
  • Half cadences and authentic cadences serve different functions in musical composition. A half cadence ends on the dominant chord, leading to a feeling of suspension and expectation for continuation. In contrast, an authentic cadence concludes on the tonic chord, providing closure and satisfaction. While half cadences create tension that invites further development, authentic cadences signify completion of musical ideas.
• Evaluate how the use of half cadences can impact voice leading in harmonic progressions involving seventh chords.
  • The use of half cadences significantly impacts voice leading in harmonic progressions with seventh chords by introducing unique challenges and opportunities for smooth transitions. When resolving to a dominant seventh chord at the end of a phrase, careful attention must be paid to maintaining proper intervals and voice independence. This creates rich textures while enhancing melodic lines. Additionally, resolving from other seventh chords into a half cadence can lead to unexpected resolutions and add depth to compositional techniques.
