Emanuel Bachʼs Keyboard Concerto Wq. 112-1 is a piece composed with a more educational purpose, characterized by its concise and approachable structure. Written in C Major, this concerto is aimed at beginners and amateur performers, and compared to his other concertos, it is smaller in scale and less technically demanding. It consists of three movements, with the first movement presenting a clear and concise theme, and the interaction between the keyboard and orchestra unfolds harmoniously. The second movement features a simple yet emotionally resonant melody, capturing the essence of Emanuel Bachʼs empfindsamer Stil. The final movement develops a lively and accessible rondo form, enhancing the joy of performance. While this concerto serves an educational purpose, it retains its musical charm, making it enjoyable for a wide range of performers from beginners to advanced musicians.
