Emanuel Bachʼs Allegro in E minor Wq. 114-11 (H. 238) is a work in his keyboard music that richly expresses a wide range of emotions. This piece is characterized by its rapid tempo and dramatic harmonic progressions, which captivate the listener with their intensity. The tension brought by the E minor key and the cleverly arranged contrapuntal elements add depth to the music. Bach employs unpredictable rhythmic changes and contrasts in dynamics to surprise and excite the audience. The improvisational elements often found in his works are particularly prominent in this Allegro. Throughout, one can feel Emanuel Bachʼs innovative compositional techniques and the richness of emotional expression he pursued.
