 O zittre nicht, mein lieber Sohn

"O zittre nicht, mein lieber Sohn" ("Oh, don't tremble, my dear son") is the first aria performed by the Queen of the Night (a famous coloratura soprano role) in Mozart's singspiel "The Magic Flute (Die Zauberflöte)".It is not as well known as the Queen's second aria, "Der Hölle Rache kocht in meinem Herzen", though no less demanding; the aria requires a soprano coloratura with extremely high tessitura and great vocal flexibility.
