Emanuel Bachʼs Keyboard Concerto Wq. 6 (H. 409) is a work in G minor composed around 1740, belonging to his early keyboard concertos from his Berlin period. This piece is characterized by its tension in the minor key and emotional depth, containing elements that foreshadow the transition to the later Empfindsamer Stil. It consists of three movements, with the first movement presenting a dramatic minor theme where the keyboard and orchestra engage in close dialogue. Based on sonata form, it features distinctive harmonic progressions and rhythmic innovations. The second movement centers on a serene and introspective melody, highlighting lyrical beauty. The final movement maintains the minor character while unfolding an energetic and lively development, offering a compelling listening experience. This concerto represents Emanuel Bachʼs early creative work, presenting an intriguing blend of Baroque elements and new musical expressions. It leaves a dramatic impression on both performers and audiences.
According to the commentary by Jane R. Stevens on Miklós Spányi's CD (BIS-CD-767) (translated by ChatGPT4o):
[In this pageʼs concerto] H. 409 [Wq. 6] (1740) and H. 421 [Wq. 18] (1745), the solo part gains significant individuality through various means. In the fast movements of these concertos, the string themes are somewhat uniform and impersonal, but the solo keyboard instrument quickly establishes its own identity by presenting its themes or transforming the tutti material to create unique music. In the slow movements, the solo further clarifies its individuality by overlaying its music on the stringʼs introductory theme. In these two works, the composer introduces what might be called "psychological complexity," where two conscious musical identities confront each other and ultimately establish some form of cooperative relationship.
