Emanuel Bachʼs Allegro in G Major Wq. 116-54 (H. 328) is a work that stands out for its emotional diversity within his keyboard music. This piece takes advantage of the bright and lively key of G major, characterized by its brisk rhythm and flowing melody. Bach skillfully employs unpredictable modulations and dynamic changes to surprise the listener. The piece features ornamental notes and improvisational elements throughout, demanding high technical skill and expressiveness from the performer. It vividly reflects the “aesthetics of emotion” in his music, leaving a profound impression on the audience.
