A dynamic work that utilizes wide-ranging arpeggios to create a sense of vast space. The piece is characterized by its grand, virtuosic gestures and sudden shifts in intensity.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: sweeping arpeggio figures that must stay smooth across positions; wide stretches that reward larger hands and clever redistribution; and sharp dynamic and character contrasts held together in one arc.
Practice secure shifts across the keyboard to execute the wide-span arpeggios with confidence.
