Ernst Wilhelm Wolf was a German composer. The most important part of Wolf's surviving oeuvre is his instrumental music. He composed at least thirty-five symphonies, of which twenty-six survive, some twenty-five harpsichord/piano concertos, more than 60 keyboard sonatas, and numerous chamber works, including string quartets, piano quintets, and other music. Stylistically these works are close to those of the composers of the Mannheim school. Particularly interesting are the harpsichord sonatas, which reflect the influence of C.P.E. Bach, and generally use more forward-looking structures. Like Bach and older masters, Wolf advocated studying counterpoint, and recommended Johann Sebastian Bach's preludes and fugues to his students; however, his views went out of fashion in late 18th century.
