Book excerpt: Goethe and Zelter spent a staggering thirty-three years corresponding. Zelter's position as director of the Sing-Akademie zu Berlin and Goethe's location in Weimar resulted in a wide-ranging correspondence. Goethe's letters offer a chronicle of his musical development, from the time of his journey to Italy to the final months of his life, while Zelter's letters retrace his path from stonemason to Professor of Music in Berlin. The 891 letters that passed between these artists provide an important musical record of the music performed in public concerts in Berlin and in the private and semi-public soirées of the Weimar court. The legacy contains a wide spectrum of letters, casual and thoughtfully composed, spontaneous and written for publication, rich with the details of Goethe's and Zelter's musical lives.
