Similar in character to Hiller's Op. 10, this work emphasizes virtuosic display through rapid figuration. It serves as an excellent study in maintaining rhythmic integrity through sustained sections of speed.
Attention must be paid to consistent phrasing within the dense, rapid textures of the main melodic lines.
