According to the commentary by Darrell M. Berg on Miklós Spányi's CD (BIS-CD-1189) (translated by ChatGPT4o):
Poco allegro ma cantabile - A Major - A lively and melodic movement combining duple and triple meter.
Andante lusingando - A minor - Composed almost entirely of triplets, this movement has a "narrative" character. Bach enhances expressiveness by adding two measures at the structural end of the second section.
Allegro - E Major - A lively piece in rounded binary form, characterized by a melodic theme known as the "Mannheim sigh," frequently appearing in the works of Bachʼs contemporaries at the Mannheim court.
