The Magic Flute (KV 620) is an opera in two acts by Wolfgang Amadeus Mozart, which was premiered in 1791 in the Freihaus Theater in Vienna. The libretto is by Emanuel Schikaneder. The roughly three-hour work is one of the world's most famous and most frequently staged operas. The arias, which include The Bird Catcher, This portrait is enchantingly beautiful and the aria of the Queen of the Night The Vengeance of Hell is boiling in my heart, are also familiar to many who have never seen the opera. Since the opera is easily accessible, it is occasionally staged in such a way that it is aimed specifically at young audiences.
