The exposition introduces the main theme in each voice, setting up a framework for subsequent development. This layered approach allows listeners to experience the intricate relationships between the melodies, resulting in a rich polyphonic texture that defines the essence of the fugue.
• Discuss how compositional techniques such as inversion and augmentation affect the thematic development within a fugue.
  • Compositional techniques like inversion and augmentation significantly enhance thematic development within a fugue. Inversion alters the direction of the melody while retaining its contour, adding variety to the texture without losing the original theme's identity. Augmentation stretches out the rhythm of the theme, allowing it to be presented in a different light. These techniques create depth and complexity as they contribute to the overall interplay between voices.
