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 sister-in-law, Josepha Hofer. This 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 (10[2])Rache,” (“dair HUH-luh RAH-kuh”) Pamina is given a knife to kill Sarastro by a character (10[1])who sings a (10[1])high F6, the Queen of (10[2])the Night.
