This is a contemporary programmatic piano work designed to evoke a sense of high-stakes tension and adventure. It utilizes driving rhythmic figures and wide-ranging arpeggios to construct its narrative arc.
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; sweeping arpeggio figures that must stay smooth across positions; and sharp dynamic and character contrasts held together in one arc.
Focus on the execution of wide-span arpeggios while keeping the rhythmic pulse steady throughout the transitions.
