This is a virtuosic toccata, characterized by its improvisatory style and rapid figuration, often in a Tarentella-like rhythm. Its distinctiveness lies in its blend of free, expressive passages with contrapuntal sections.
Requires excellent finger dexterity and control to execute the rapid, cascading runs and intricate polyphonic lines.
