By the time of Emperor Joseph II’s death in 1790 Beethoven was a member of the court musical establishment in Bonn. To mark the occasion, Beethoven was commissioned to write to cantatas, one to mourn Joseph’s death and the other to celebrate the accession to the throne of Emperor Leopold II. Although Beethoven was only 19 years old at the time, both works show the embryonic marks of his greatness: intense expression and control of structure in one, and an almost operatic panache in the other. Neither piece was performed during Beethoven’s lifetime.
