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 composer wrote to highlight the range of his (10[1])sister-in-law, (10[1])Josepha Hofer. This opera’s librettist Emmanuel Schikaneder premiered a character who falsely brags about killing (10[1])a snake, leading his mouth to (10[1])be padlocked. In this opera’s aria “Der (10[1])Hölle Rache,” (“dair HUH-luh RAH-kuh”) Pamina is given a knife to kill Sarastro by a character who sings a (10[1])high (10[1])F6, (10[1])the Queen of the Night. For 10 points, name this Wolfgang Amadeus Mozart opera titled for a supernatural woodwind instrument. ■END■
