Review Questions

• How does the dominant section contribute to the overall structure of a musical piece?
  • The dominant section is critical for creating tension that prepares listeners for resolution. By emphasizing the dominant chord, which often leads back to the tonic, this section helps establish expectations for what comes next. Its placement within a chord progression guides the overall structure and flow of the piece, marking important moments where tension heightens before resolution.
• Discuss how different types of chords in the dominant section affect its function and effectiveness.
  • The effectiveness of the dominant section largely depends on the types of chords used within it. For instance, using a dominant seventh chord introduces more dissonance and tension compared to just using a major triad. This added complexity makes the eventual resolution to the tonic more satisfying. Additionally, incorporating secondary dominants or altered chords can further enhance the harmonic interest and lead to unique resolutions.
• Evaluate how variations in dominant sections can alter emotional impact and listener expectations in various genres.
  • Variations in how dominant sections are approached can significantly influence the emotional impact of a piece. For example, using unconventional progressions or extending tension with additional chords can create suspense or surprise. In genres like jazz or modern pop, altering standard dominant functions can challenge listener expectations and evoke different feelings. By playing with established norms, composers can manipulate emotional responses and keep their audience engaged.
