ChatGPT4o writes as follows (please note that it may not be accurate):
Emanuel Bachʼs Sonata in C Major Wq 63-1 (H. 70) is a captivating work that showcases his diverse musical style. This sonata consists of three movements, each possessing a distinct character. The first movement begins with a gentle yet lively tempo, inviting the audience into a world of elegant music. The second movement is more introspective, characterized by an emotionally rich melody with profound expressiveness. The final third movement incorporates a classical dance form, offering a light and rhythmic finale. This sonata not only demonstrates Bachʼs creativity and technical prowess but also reflects the musical trends of his time.
According to the commentary by Darrell M. Berg on Miklós Spányi's CD (BIS-CD-1189) (translated by ChatGPT4o):
Allegretto tranquilamente - C Major - A simple and melodic piece.
Andante ma innocentemente - E Minor - Also a melodic piece with a somewhat complex structure in a developed binary form (the initial melodic idea returns in the original key before the conclusion).
Tempo di Minuetto con tenerezza - G Major - A stylized dance movement that maintains the calm and reassuring character of the first two movements.
