Emanuel Bachʼs Sonata in G minor Wq. 52/3 (H. 158) is one of the most emotionally rich works in his keyboard music. This sonata, while influenced by his father Johann Sebastian Bach, possesses its own unique expressiveness. The first movement is characterized by its graceful and affectionate melody, which brings a sense of calm to the listener. The second movement features a lively and rhythmic motion, reflecting Bachʼs humor and wit. The final third movement presents a powerful and dynamic development, bringing the piece to a close. This sonata demonstrates Emanuel Bachʼs wide range of emotional expression and his innovation during the transition to Classical music.
