This etude focuses on advanced scale sequences and rapid technical shifts. It is distinctive for its rigorous demands on finger agility and consistency of tone across the keyboard register.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: fast passage work that stays light and even at tempo; fine finger independence within the hand; and precise articulation — the difference between crisp and blurred is the piece.
The technical obstacle involves coordinating rapid finger transitions while preserving a smooth, cantabile quality.
