Composed in 1939, Emanuel Bachʼs Sonata in G minor Wq. 65/11 (H. 21) is one of the most emotionally rich and expressive works among his keyboard music. This sonata is a quintessential example of Bachʼs unique style, showcasing his innovation during the transitional period to Classical music. The first movement begins with a powerful and dramatic introduction, characterized by a more free and emotional expression while retaining Baroque influences. The following second movement has a calm and introspective atmosphere, with a melody that evokes deep emotions. The final third movement offers a light and graceful finale, balancing the entire piece. This sonata is an excellent example of the emotional diversity in Emanuel Bachʼs music and his forward-thinking compositional techniques, making it particularly popular among performers.
