Missa In Dis „Die Zauberflöte” Z Dawnego Rękopisu Kościoła Św. Mikołaja W Bielsku-Białej. Dzieło Mozarta Czy Mistyfikacja? / Missa In Dis “Die Zauberflöte” From The Old Manuscript In St. Nicholas Church In Bielsko-Biała. Mozart’S Piece Or A Hoax?
The article is devoted to a previously entirely unknown vocal-instrumental mass preserved in St. Nicholas Church in Bielsko-Biała. Missa in Dis - signed with Mozart’s name - is a composition based on the material of Mozart’s singspiel Die Zauberflöte. The article contains the description of the manuscript and its history, discusses the question of the forces of the mass, the problem of mutual relationships between the sound substance of Missa in Dis and The Magic Flute, and dwells extensively on the question of who the author of the piece was: between a hypothesis that the mass might have been composed by Mozart and a supposition that we are dealing with a late 18th/early 19th-century mystification concerning the composer.
