Review Questions

• How does the tonic function within a scale and its relationship to other notes?
  • The tonic functions as the first note of a scale and establishes the tonal center around which all other notes revolve. It serves as the foundation for harmony and determines the key signature of a piece. Other notes in the scale, especially the dominant note, create tension that naturally resolves back to the tonic, reinforcing its importance in establishing musical structure.
• In what ways does understanding the tonic contribute to analyzing harmonic progressions in music?
  • Understanding the tonic is vital for analyzing harmonic progressions because it reveals how chords relate to each other within a key. When musicians identify the tonic chord, they can see how other chords function in relation to it, such as dominant chords that lead back to the tonic. This insight into how harmony is constructed helps musicians anticipate resolutions and understand compositional techniques used by composers.
• Evaluate how different musical genres utilize the concept of tonic to create unique tonal experiences.
  • Different musical genres leverage the concept of tonic to establish distinctive tonal experiences. For example, classical music heavily relies on traditional harmonic practices centered around the tonic for structure and resolution.
