Emanuel Bachʼs Prussian Sonata No. 1 in F Major Wq. 48-1 (H. 24) is a keyboard piece dedicated to King Frederick II of Prussia, published in 1742. It exemplifies the characteristics of Emanuel Bachʼs empfindsamer Stil (sensitive style). The first movement progresses at a gentle pace, adopting the sonata form while combining elegance with delicate emotions. The second movement has a lyrical and introspective atmosphere, highlighting the beauty of the melody and the ingenuity of the harmony. The third movement is a lively and dynamic finale, characterized by a dance-like rhythm. This sonata is appealing for its clarity of form and diverse emotional expression, and it was composed with performance on the [clavichord,] harpsichord, or fortepiano in mind. It is a piece that encapsulates Emanuel Bachʼs creativity.
