ChatGPT4o writes as follows (please note that it may not be accurate):
Wq. 117/33 "La Capricieuse" (H. 113) is one of the character pieces composed by Emanuel Bach, with a title that means "The Capricious One." This work, while based on the mid-18th century galant style, is imbued with unique emotional expression and drama. Musically, it is characterized by sudden rhythmic changes and unpredictable melodic movements, skillfully expressing "capriciousness." In particular, the structure, where pointillistic rhythms and short phrases switch rapidly, creates an atmosphere that perfectly matches the title. It is a piece that reflects Emanuel Bachʼs humor and creativity, requiring performers to have expressive and improvisational skills. This piece is among the most popular of his character pieces and is often performed on the clavichord or harpsichord.
