Emanuel Bachʼs Sonata in G minor Wq. 51-6 (H. 62) is one of the most emotionally expressive works among his keyboard music. This sonata, while influenced by his father Johann Sebastian Bach, possesses its own unique expressiveness. The first movement is characterized by a powerful and passionate melody, filled with energy that captivates the listener. The second movement exudes a calm and introspective atmosphere, expressing deep emotions. The final third movement features a lively and rhythmic motion, balancing the overall composition. This sonata not only demonstrates Emanuel Bachʼs innovative musical style but also serves as a bridge to classical music.
