In a single winter evening at Vienna’s Theater an der Wien, Ludwig van Beethoven reshaped the future of Western music. Conducting from the piano, he unveiled an astonishing program: the dramatic Fifth Symphony, the pastoral Sixth Symphony, the lyrical Fourth Piano Concerto, and the innovative Choral Fantasy. This marathon concert tested both performers and audience, yet it revealed Beethoven’s genius in full force. The Fifth thundered with fate itself, while the Sixth painted nature in sound. Despite cold halls and limited rehearsal, the event became legendary—an audacious declaration of Beethoven’s artistic vision that still resonates through concert halls today.
