This piece is also one of the most famous in the collection of Preludes. It is in ternary form. From the outset, the solemn theme gradually develops rhythmic motion. After the meno mosso middle section, the music builds to an intense climax, marked Allegro and più vivo. The main section, reappearing, is highly ornamented, and at poco più vivo, it demands a rich and full sound that can be said to reach the limits of the piano's capabilities. With a performance time of around seven minutes, it is a grand piece befitting the conclusion of the Preludes.
