Review Questions

  • How does diminution enhance thematic development in sonata form?

This adds complexity and interest to the development section, where themes are transformed and explored. By incorporating diminution, composers create a sense of movement and excitement while still maintaining connections to the original material.
  • In what ways does diminution function within the context of fugal writing and counterpoint?
    • In fugal writing, diminution serves as a crucial tool for developing subjects by elaborating on them through intricate note patterns. As voices enter with variations of the subject, diminution creates rich textures that highlight counterpoint's complexity. This interplay not only emphasizes each voice's independence but also showcases the overall unity of the composition through carefully constructed melodic lines.
