Review Questions

• How does harmonic structure influence the overall mood of a piece of music?
  • Harmonic structure directly affects the mood by determining how chords relate to one another and how they create tension or resolution. For instance, a piece featuring frequent dominant-to-tonic resolutions tends to evoke a sense of stability and satisfaction, while unexpected chord changes may generate feelings of surprise or tension. Composers use these harmonic relationships intentionally to evoke specific emotional responses from the listener.
• In what ways do chord progressions contribute to the development of harmonic structure in different musical genres?
  • Chord progressions are fundamental to harmonic structure as they dictate the sequence in which chords appear. Different genres have characteristic progressions that define their sound; for example, jazz often utilizes extended harmonies and complex progressions, while pop music frequently relies on simple, repetitive patterns. These stylistic choices shape the listener's experience and highlight the uniqueness of each genre's harmonic identity.
• Evaluate the significance of cadences in establishing harmonic structure and their role in musical form.
  • Cadences are crucial for establishing harmonic structure as they signal the end of phrases or sections within a piece. They help create a sense of closure or anticipation, guiding listeners through the music's form. The choice of cadence—whether it's a perfect authentic cadence providing strong resolution or a deceptive cadence leaving tension unresolved—can greatly affect how a piece is perceived and understood, highlighting its emotional journey.
