At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. The main demands: fast passage work that stays light and even at tempo; sweeping arpeggio figures that must stay smooth across positions; and ornaments that need to sound effortless, not squeezed in.
Beyond that, expect a true singing tone, with the melody floating above the accompaniment.
The technical challenge involves maintaining a light touch during the rapid-fire ornamental passages in the higher register.
