Così fan tutte pasticcio Coronation Mass

The Coronation Mass in C major, K. Deest is a parody mass based on Wolfgang Amadeus Mozart's opera Così fan tutte that was offered to Simrock by Carl Zulehner who had also sold the manuscript of the Mass in G major, K. Anh. 232 to the music publisher, with the claim that it was a Mozart "Coronation Mass".
