ChatGPT4o writes as follows (please note that it may not be accurate):
Emanuel Bachʼs character piece "Louise" (La Louise, Wq. 117/36) is a delicate and emotionally rich work included in the 1765 collection of character pieces. Set in A minor, it is distinguished by its gentle lyricism and inner depth. The title suggests a dedication or sentiment towards a specific individual, evoking a sense of personal intimacy. The use of ornamentation and harmonic shifts exemplifies the characteristics of the Empfindsamer Stil (sensitive style), creating a poetic atmosphere despite its brevity. Performers are required to deliver a nuanced performance that finely expresses emotion in this piece.
