Between 1837 and 1840, Theodor Uhlig studied under Johann Christian Friedrich Schneider at the music school in Dessau, which Schneider had founded as part of his work as court Kapellmeister of Anhalt-Dessau. Uhlig, having received a royal scholarship, was trained directly by Schneider, who was an established organist, pianist, composer, and pedagogue. Schneider’s long-standing pedagogical reputation, strengthened by his earlier work in Leipzig and his publication of the widely used textbook "Elementarbuch der Harmonie und Tonsetzkunst," contributed to the rigorous musical environment in which Uhlig was educated.
During this period in Dessau, Schneider served as Uhlig’s principal teacher, providing him with formal musical training and shaping his early development as a violinist, composer, and future critic. As one of the many students who passed through Schneider’s influential school—alongside musicians such as Fritz Spindler and Friedrich Lux—Uhlig benefited from a comprehensive curriculum designed by a master who was also known for major achievements as a performer, including being the first interpreter of Beethoven’s Piano Concerto No. 5. This teacher–student relationship formed the foundation of Uhlig’s later career in Dresden.
