ChatGPT4o writes as follows (please note that it may not be accurate):
Emanuel Bachʼs Sonata in A Minor Wq. 65/25 (H. 61) is one of the most emotionally rich and expressive works in his keyboard music. This sonata, while influenced by his father Johann Sebastian Bach, showcases a unique style that marks the transition to the Classical period. The first movement begins at a calm tempo, creating a somber atmosphere in A minor. The following second movement unfolds a more serene and introspective melody, evoking deep emotions in the listener. The final third movement, with its lively rhythm and dynamic development, powerfully concludes the entire sonata. This work is an excellent example of Emanuel Bachʼs emotional expressiveness and the musical innovations of his time, highlighting the influence his music had on later composers.
