Emanuel Bachʼs **Fugue in C minor Wq. 119-7 (H.75-5)** is a dramatic work filled with dark, heavy tones and tension. The opening theme is presented with a melody imbued with the shadows characteristic of the minor key, revealing inner turmoil and deep emotions. The voices intricately intertwine, and amidst the strict counterpoint, Bachʼs unique, emotionally rich expression stands out. In the middle section, modulations and the development of counter-melodies are skillfully incorporated, sustaining the tension while bringing a rich dynamism to the music. The contrast between the heavy movement in the bass and the sharp melodies in the treble creates a coexistence of strength and delicacy throughout the piece. In the final section, the theme is majestically recapitulated, reaching a dramatic climax before concluding powerfully. This fugue, while grounded in the contrapuntal techniques inherited from his father, Johann Sebastian Bach, highlights Emanuel Bachʼs distinctive empfindsamer Stil, characterized by its introspective and passionate expression. The profound tension and dramatic structure leave a strong impression on the listener.
