 Only a few orphicas were made in Vienna from 1795 to 1810; about 30 orphicas are still in existence today.Among the few composers writing for the orphica was Ludwig van Beethoven.According to a letter of Beethoven's friend Franz Gerhard Wegeler from December 23, 1827, Wegeler had "2 Stückchen für die Orphica, die Bhven für meine Frau componirte" ('2 small pieces for the orphica which Beethoven composed for my wife').
