History, drama, and music come to life through a lively exchange of letters between young Christoph and his uncle about the "madman" upstairs -- Beethoven himself. As Christoph learns about the composer's genius and struggles, audiences are captivated by the master's music, including the Moonlight Sonata, Für Elise, and the great Fifth and Ninth Symphonies. The music is magically woven into the drama as two actors share their anecdotes and observations based on true incidents from the composer's life.
