<Tr> <Td_colspan="3"> Priests, women, people, slaves, chorus </Td> </Tr> <P> The names of the performers at the premiere are taken from a preserved playbill for this performance (at right), which does not give full names; "Hr ." = Herr, Mr.; "Mme ." = Madame, Mrs.; "Mlle ." = Mademoiselle, Miss . </P> <P> While the female roles in the opera are assigned to different voice types, the playbill for the premiere performance referred to all of the female singers as "sopranos". The casting of the roles relies on the actual vocal range of the part . </P> <P> The work is scored for two flutes (one doubling on piccolo), two oboes, two clarinets (doubling basset horns), two bassoons, two horns, two trumpets, three trombones (alto, tenor, and bass), timpani and strings . It also requires a four - part chorus for several numbers (notably the finales of each act). Mozart also called for a stromento d'acciaio (instrument of steel) to perform Papageno's magic bells; an instrument which has since been lost to history, though modern day scholars believe it to be a keyed glockenspiel, which is usually substituted with a celesta in modern - day performances . </P>

How long did it take mozart to write the magic flute
