What is the structure of the last waltz by Chopin?

Chopin's "Valse Brillante" in D-flat major, Op. 64, No. 1, commonly known as the "Minute Waltz," consists of a ternary (ABA) structure. The A section features a lively, dancing theme characterized by its rapid tempo and playful motifs. The contrasting B section introduces a more lyrical and expressive melody, providing a moment of contrast before returning to the exuberant A section for a final flourish. This structure, along with its intricate embellishments, showcases Chopin's unique style and virtuosity.
