Review Questions

• How does the use of sequence contribute to thematic development in Classical music?
  • The use of sequence enhances thematic development by allowing motifs to be repeated at different pitch levels, creating a sense of evolution. This repetition with variation helps listeners recognize and connect with the themes as they transform. By employing sequences, composers can build emotional intensity and maintain interest throughout their compositions.
• Analyze the impact of sequence on the structure of a typical Classical sonata form.
  • In a Classical sonata form, sequences play a vital role in both the exposition and development sections. They can help expand on initial themes presented in the exposition by introducing variations that maintain continuity while also allowing for exploration. In the development section, sequences often facilitate modulation to different keys, creating tension and complexity that resolves as the piece returns to the recapitulation.
• Evaluate how the use of sequence distinguishes Classical music from earlier musical styles.
  • The incorporation of sequence is one of the distinguishing features that sets Classical music apart from earlier styles like Baroque music. While Baroque composers focused on ornamentation and complex counterpoint, Classical composers emphasized clarity, balance, and thematic development through techniques such as sequence. This shift allowed for more expressive and structured compositions that catered to the evolving tastes of audiences during the Classical period.
