Smetana’s piano works reflect both his nationalist Czech identity and the virtuosic tradition of Liszt. This piece stands out for its light, whimsical character that alternates between delicate runs and sudden, brilliant flourishes.
The performer must maintain a light, sparkling touch throughout the fast, flowing sixteenth-note passages.
