Christian Gottlob Neefe flourished as the Baroque was giving way to the Classical period. These Twelve Sonatas represent important steps in this transition, each having a uniquely individual character and showing a mixture of styles. Neefe is remembered today as Beethoven's first main teacher in Bonn, the Dressler Variations being young Ludwig's first published composition.
