Emanuel Bachʼs Sonata in F Major Wq. 50-01 (H. 136) is one of the particularly captivating works among his keyboard music. This sonata is composed of three movements, each possessing a distinct tempo and atmosphere. The first movement is characterized by a lively and bright melody, offering an inviting familiarity that draws the listener in. The following second movement is a slow, deeply emotional piece that conveys an introspective beauty.
