By doing so, each voice can move independently while still anchoring the overall sound to the cantus firmus, making it a key element in achieving polyphonic intricacy.
• Discuss how the use of Cantus Firmus evolved during the Renaissance period compared to earlier medieval practices.
  • During the Renaissance, Cantus Firmus became more sophisticated as composers began manipulating the fixed melody through techniques such as inversion and retrograde. Unlike earlier medieval practices where it was primarily used as a simple foundation, Renaissance composers like Josquin des Prez incorporated it into intricate counterpoint and polyphonic structures. This evolution not only enriched musical texture but also highlighted individual creativity in composition.
• Evaluate the impact of Cantus Firmus on the development of Western classical music and its relevance in modern compositions.
  • Cantus Firmus has had a lasting influence on Western classical music by establishing foundational principles of counterpoint and harmony that composers continue to explore.
