In his Bonn works, Beethoven presents a Galant sensibility by gathering short phrases based on stock melodic events for courtly amusement. At the same time, he wrestles with the evolution of sonata form as a vehicle for serious personal expression. To promote an understanding of these conflicting goals, this lecture contextualizes transitional points in Beethoven\&##39;s Bonn works with those of his closest mentors (Neefe, Luchesi and Sterkel) and shows how these early approaches leave marks in some mature sonatas.
