This sonata consists of three movements, each possessing a distinct character. The first movement is characterized by lively, bright melodies and rhythmic motion, making it a powerful opening that draws in the audience. The second movement is notable for its calm and emotionally rich melody, showcasing deep expressiveness. The final third movement returns to a lively tempo, concluding with virtuosic passages and an energetic finale.
