Emanuel Bachʼs Rondo in B-flat Major Wq. 58-05 (H. 267) is one of the most emotionally rich pieces among his keyboard works. This rondo, while influenced by his father Johann Sebastian Bach, possesses its own unique expressiveness. The piece skillfully weaves various emotional changes amidst the repetition of a bright and lively theme. Particularly, the unexpected modulations and rhythmic changes captivate the listener. The "diversity of emotions," typical of Emanuel Bachʼs style, is evident, requiring performers to deliver an expressive interpretation. This rondo serves as an example of the evolution of music in his era and plays a role as a bridge to classical music.
