Sarastro - Composition

Composition

The opera was the culmination of a period of increasing involvement by Mozart with Schikaneder's theatrical troupe, which since 1789 had been the resident company at the Theater auf der Wieden. Mozart was a close friend of one of the singer-composers of the troupe, tenor Benedikt Schack (the first Tamino), and had contributed to the compositions of the troupe, which were often collaboratively written. Mozart's participation increased with his contributions to the 1790 collaborative opera Der Stein der Weisen (The Philosopher's Stone), including the duet ("Nun liebes Weibchen", K. 625/592a) and perhaps other passages. Like The Magic Flute, Der Stein der Weisen was a fairy-tale opera and can be considered a kind of precursor; it employed much the same cast in similar roles.

The libretto for The Magic Flute, written by Schikaneder, shares much of its plot and many of its characters with the Singspiel Oberon, written by Karl Ludwig Giesecke for the Schikaneder troupe two years earlier (and set to music by Paul Wranitzky) as a re-adaptation of Sophie Seyler's Singspiel Hüon und Amande.

Mozart evidently wrote keeping in mind the skills of the singers intended for the premiere, which included both virtuosi and ordinary comic actors, asked to sing for the occasion. Thus, the vocal lines for Papageno—sung by Schikaneder himself—and Monostatos (Johann Joseph Nouseul) are often stated first in the strings so the singer can find his pitch, and are frequently doubled by instruments. In contrast, Mozart's sister-in-law Josepha Hofer, who premiered the role of the Queen of the Night, evidently needed little such help: this role is famous for its difficulty. In ensembles, Mozart skillfully combined voices of different ability levels.

The pitch ranges of two of the original singers for whom Mozart tailored his music have posed challenges for many singers who have since recreated their roles. The Queen of the Night's "Der Hölle Rache kocht in meinem Herzen" ("The vengeance of Hell boils in my heart") reaches a high F6, rare in opera. At the low end, the part of Sarastro, premiered by Franz Xaver Gerl, includes a conspicuous F in a few locations.
