This piece is a classic example of Mendelssohn's 'elfin' style, featuring rapid-fire arpeggiated figures and light, agile textures. It serves as a brilliant showpiece that requires high-level finger dexterity and crisp articulation.
The main technical hurdle is maintaining evenness and clarity during the rapid, delicate sixteenth-note passagework found throughout the piece.
