Emanuel Bachʼs Solfeggio in G Major Wq. 112-04 (H. 145) is one of the most renowned pieces among his keyboard works. This piece, though brief, is characterized by its highly energetic melody and rhythm, demanding advanced technical skills from the performer. The rapid passages and brilliant ornamentations interwoven throughout leave a strong impression on the audience. Through this work, Bach skillfully expresses sudden emotional shifts and contrasts. It exemplifies the “aesthetics of emotion” in his music and serves as a bridge to Classical music. For performers, it is a challenging piece that tests both expressive and technical abilities.
