Emanuel Bachʼs Prussian Sonata No. 3 in E Major, Wq. 48-3 (H. 26), is a work characterized by the brightness and sophistication of its E major key, and is part of a set of six sonatas dedicated to King Frederick II of Prussia, published in 1742. The first movement is in a sonata form with a gentle and light tempo, providing a clear and graceful impression through the development of its themes. The second movement is a leisurely, lyrical section heavily influenced by the empfindsamer Stil, captivating listeners with its deep emotional expression. The third movement is a lively finale with a fast tempo, marked by its dynamic rhythm. This sonata is a balanced work of formal beauty and emotional expression, showcasing Emanuel Bachʼs creativity to the fullest. Performances on the clavichord, harpsichord, or fortepiano allow one to experience the atmosphere of the time.
