ChatGPT4o writes as follows (please note that it may not be accurate):
Wq. 117/28 "La Complaisante" (H. 109) is one of Emanuel Bachʼs character pieces, with a title meaning "The Gentle Person" or "The Considerate Person." This work embodies the elegant and serene atmosphere of the 18th-century galant style, characterized by its refined melodies and gentle harmonies. The piece follows a typical ternary form (A-B-A), where the middle section features lively movement, yet the overall calmness is maintained throughout. The melody is richly ornamented, requiring the performer to exhibit nuanced expressiveness. It is a work that highlights Emanuel Bachʼs individuality, combining approachability with musical depth within his keyboard music. Performances on the clavichord or harpsichord are particularly suitable, as their timbres enhance the pieceʼs gracefulness. This work is cherished by many performers and audiences as a quintessential example of Emanuel Bachʼs galant style.
\Berg<1087>"This ternary form (A-B-A) piece may have been modeled after Dandrieuʼs concise and elegant rondeau (a piece with a recurring refrain) of the same name. While the middle section becomes lively, its flowing smoothness is never compromised."
