Emanuel Bachʼs Sonatina in F Major Wq. 63-11 (H. 296) is one of the works that demonstrate his diverse musical style. This sonatina, while influenced by his father Johann Sebastian Bach, pursues its own unique expression and serves as a bridge to classical music. The piece has a lively and bright atmosphere, giving the audience a sense of familiarity. Formally, it is based on the traditional sonata form, yet it showcases Emanuel Bachʼs characteristic free development. Notably, the richness of emotional expression and unpredictable modulations in his music are distinctive. This sonatina is written for keyboard instruments and presents both a technical challenge and a test of expressiveness for the performer. It is a piece where one can feel the charm of Emanuel Bachʼs music.
