Emanuel Bachʼs Sonata in D Minor Wq. 112-07 (H. 179) is a work that showcases his creativity and rich emotional expression. The first movement is light yet carries an underlying tension that captivates the listener. The following second movement exudes a deep sadness and introspective atmosphere, with a melody that leaves a lasting impression on the heart. The final movement is full of lively energy, yet it maintains a balanced development without rushing excessively. This sonata is a testament to Emanuel Bachʼs wide emotional range in music and his timeless expressiveness.
