Emanuel Bachʼs Sonata in D minor Wq. 52-02 (H. 142) is one of the most distinctive works among his keyboard music. This sonata consists of three movements, each with a different tempo and character. The first movement is characterized by a lively yet tense melody. The second movement exudes a quiet and introspective atmosphere, requiring delicate expression. The final third movement is a lively finale, featuring many technically challenging passages, making it a demanding piece for performers. This sonata not only showcases Emanuel Bachʼs unique musical style but also reflects the transition of music in his era.
