The Magic Flute, K. 620, is an opera in two acts by Wolfgang Amadeus Mozart to a German libretto by Emanuel Schikaneder. It is a Singspiel, a popular form that included both singing and spoken dialogue. The work premiered on 30 September 1791 at Schikaneder's theatre, the Freihaus-Theater auf der Wieden in Vienna, just two months before Mozart's death. It was Mozart's last opera. It was an outstanding success from its first performances, and remains a staple of the opera repertory.
