Composed during Mozart's influential visit to Mannheim, this vibrant sonata showcases the brilliant keyboard style and orchestral influences characteristic of the Mannheim school. The first movement, marked Allegro con spirito, features energetic themes, dynamic contrasts, and the precise articulation typical of Mozart's mature piano writing.
