Performing a glissando in “Gnomus” from Mussorgsky’s Pictures at an Exhibition requires precision and technique due to its dramatic and expressive nature. Here’s a step-by-step guide to help you execute it effectively:

Steps to Perform Glissando in Gnomus:

  1. Understand the Passage: Identify the section in Gnomus where the glissando appears. It’s often used for a sudden, eerie effect that matches the piece’s disjointed, grotesque character.
  2. Position Your Hand: Align your hand comfortably across the keyboard with fingers relaxed to glide smoothly over the keys.
  3. Choose the Right Fingering: Use the back of your fingernails for black keys or your fingertips for white keys, depending on the passage.
  4. Practice Gradually: Start slow to ensure an even and fluid motion. Focus on achieving clarity and a steady dynamic rather than speed initially.
  5. Add Expression: Once mastered, incorporate dynamic changes and tonal intensity to match the piece’s mood.

Mastering the glissando in Gnomus requires practice but adds to the drama and tension that makes the piece so iconic.
