Review Questions

• How does understanding sentence structure enhance the analysis of a musical composition?
  • Understanding sentence structure allows for a deeper analysis of how musical phrases are organized and related, which is vital in interpreting a composition's overall form. It helps identify how composers develop themes through repetition and variation, revealing their intentions behind emotional contrasts. By recognizing these structures, analysts can see the connections between different sections and appreciate how they contribute to the narrative of the piece.
• Compare the roles of phrases and sentences within musical structures. How do they work together to create coherence in music?
  • Phrases serve as smaller units of musical thought that express complete ideas, while sentences are larger constructs made up of multiple phrases working together. Phrases often contain clear beginnings and endings with cadences, creating smaller moments of closure, while sentences connect these phrases to form overarching themes or motifs. Together, they establish coherence by allowing composers to build on ideas, providing listeners with an understandable flow throughout the composition.
• Evaluate how variations in harmonic rhythm can influence the perception of sentence structure in a piece of music.
  • Variations in harmonic rhythm can significantly impact how listeners perceive sentence structure by altering the sense of movement and tension within phrases. For instance, accelerating harmonic changes may create heightened anticipation leading into a cadence, making the resolution feel more satisfying. Conversely, slower harmonic rhythms might create a sense of stasis or contemplation within a sentence. By manipulating these rhythms, composers can evoke different emotional responses, shaping how audiences experience the underlying structure of their music.
