Emanuel Bachʼs **Fugue in G minor, Wq. 119-5 (H.101-5)** is a dramatic work imbued with deep shadows and tension. The opening theme is presented with a weighty and introspective melody characteristic of the minor key, and unfolds with a meticulous structure through strict counterpoint. Each voice intertwines closely, skillfully expressing tension and inner passion. In the middle section, modulations and variations of the theme are interwoven, creating a contrast between tension and relaxation. The progression of the music is introspective yet powerful, with a gradually increasing tension that emphasizes the dramatic nature of the piece. In the final section, the theme is powerfully recapitulated, concluding the work with overwhelming energy. This fugue is a masterpiece that inherits the tradition of strict counterpoint from his father, Johann Sebastian Bach, while blending Emanuel Bachʼs unique empfindsamer Stil. The richly shaded melodies and intricate structure leave a profound impression on the listener.
