Expostulations functions as a character piece with shifting emotional states and sudden shifts in texture. It utilizes chromatic passing tones to create a sense of agitation and resolve.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: precise articulation — the difference between crisp and blurred is the piece; chord voicing — bringing out one note inside a handful of others; and sharp dynamic and character contrasts held together in one arc.
Managing the rapid transitions between contrasting sections requires excellent hand preparation and rhythmic stability.
Comparable difficulty and character — good candidates for what to learn next.
