Composed in 1834, but published in 1918, more than half a century after Chopin's death. It is dedicated to Pierre Wolff with the words "My Friend". Although not marked "Prélude" in the autograph manuscript, given that Chopin referred to this work as a "Prélude" in a letter to his friend Fontana, it is today counted as one of Chopin's Préludes.

This work in A-flat major, marked Presto con leggerezza, is characterized by its perpetuum mobile nature, dominated by sixteenth notes throughout.
