This piece combines rapid, trill-like figures with cluster accents to create a shimmering, virtuosic effect. It requires high technical facility and a light, nimble touch to execute the fast ornamentation.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: fast passage work that stays light and even at tempo; ornaments that need to sound effortless, not squeezed in; and fine finger independence within the hand.
The technical challenge is the rapid, precise execution of trills and clusters while maintaining a vivacious tempo.
