Review Questions

• How does the use of glissandi enhance the expressive qualities of Impressionist music?
  • Glissandi enhance the expressive qualities of Impressionist music by allowing performers to create smooth transitions between pitches, which adds an element of fluidity and emotional depth. This technique aligns with the Impressionist focus on atmosphere and mood, enabling composers like Debussy and Ravel to evoke imagery and sensations that resonate with listeners. The sliding effect produced by glissandi helps to blur boundaries between notes, mirroring the hazy qualities found in Impressionist art.
• Discuss how glissandi differ from similar techniques like portamento and how each contributes to a composer's stylistic approach.
  • While both glissandi and portamento involve sliding between pitches, they differ in execution; glissandi typically connect two distinct notes quickly while maintaining clarity between them, whereas portamento creates a more continuous glide without defined intervals. Composers may choose one over the other depending on their desired expressive effect—glissandi might be used for dramatic moments or transitions, while portamento could convey tenderness or longing. Each technique enhances a composer's unique style by shaping how melodic lines are perceived emotionally.
• Evaluate the role of glissandi in establishing the overall aesthetic of Impressionism and its impact on subsequent musical movements.
  • Glissandi play a crucial role in establishing the overall aesthetic of Impressionism by introducing fluidity and color into melodies, which mirrors the movement's emphasis on sensory experience over strict structure. This technique allowed composers like Debussy and Ravel to break free from traditional harmonic constraints and create lush soundscapes that evoke natural imagery. As a result, glissandi influenced later musical movements such as jazz and contemporary classical music, where expressive techniques became essential for conveying emotion and atmosphere in composition.
