Presto: Extremely fast

The structure is A + B + A' + B + A'' + Coda. Section A, which possesses the vigor and brilliance of fireworks, and Section B, characterized by elusive, floating arpeggios, appear alternately, and the Coda is derived from the material of Section A. In Section A, repeated double notes continue pp, building up rapidly with a cresc. from measure 13. These repeated double notes are reminiscent of the opening of the first movement of Piano Sonata No. 21 in C major, 'Waldstein,' Op. 53, which was composed between 1803 (the same year Bagatelles Op. 33 was published) and 1804. The way Section A becomes increasingly subdivided with each repetition also resembles the variation technique of the first theme in the same sonata. The fantastical writing in Section B, where the bass continues to resonate with a long pedal, is reminiscent of the final movement of the same sonata. It is a dynamic piece, fitting to conclude the collection.
