This opera’s overture opens with the three-chord sequence of E-flat major, C minor, E-flat major said to represent knocking. The rising notes (read slowly) D, F, B-flat are each sung on the word “Hört” (“hert”) in an aria that this opera’s (10[1])composer wrote to highlight the range of his sister-in-law, (10[1])Josepha Hofer. This (-5[1])opera’s librettist Emmanuel Schikaneder premiered a character who falsely brags about killing a snake, leading his mouth to be padlocked. In this opera’s aria “Der Hölle Rache,” (“dair HUH-luh RAH-kuh”) Pamina is given a knife to (10[1])kill Sarastro by a character who sings a high F6, the Queen of (10[1])the Night. For 10 points, name this Wolfgang Amadeus Mozart opera titled for a supernatural (10[1])woodwind (10[1])instrument. ■END■
