The Magic Flute in the context of "Oberon (Seyler)"

Scenic design, also known as stage design or set design, is the creation of scenery for theatrical productions including plays and musicals. The term can also be applied to film and television productions, where it may be referred to as production design. Scenic designers create sets and scenery to support the overall artistic goals of the production. Scenic design is an aspect of scenography, which includes theatrical set design as well as light and sound.

Modern scenic designers are increasingly taking on the role of co-creators in the artistic process, shaping not only the physical space of a production but also influencing its blocking, pacing, and tone. As Richard Foreman famously stated, scenic design is a way to "create the world through which you perceive things happening." These designers work closely with the director, playwright, and other creative members of the team to develop a visual concept that complements the narrative and emotional tone of the production. Notable scenic designers who have embraced this collaborative role include Robin Wagner, Eugene Lee, and Jim Clayburgh

The keyboard glockenspiel (French: jeu de timbre) or organ glockenspiel is an instrument consisting of a glockenspiel operated by a piano keyboard. It was first used by George Frideric Handel in the oratorio Saul (1739). It was also used in the 1739 revivals of his Il Trionfo del Tempo and Acis and Galatea, and the next year in L'Allegro, il Penseroso ed il Moderato. Half a century later, Wolfgang Amadeus Mozart employed a strumento d'acciaio in The Magic Flute (1791) to represent Papageno's magic bells. It is now considered proven that Mozart meant a keyboard glockenspiel.

From the 19th century onwards, the keyboard glockenspiel fell into the background due to the introduction of the celesta in 1886, which, due to its larger range and more modern construction, could also play more difficult glockenspiel parts.[9] In contrast to the very soft sound of the celesta (produced by the felt hammers of the playing mechanism), the historical keyboard glockenspiel had a very clear, metallic sound. Its sound plates were struck with steel or hard plastic clappers. It had no sound-enhancing soundboard and usually had a range of 2 to 2.5 octaves. There are also a smaller number of historical instruments with a range of 3 1/3 octaves (C5–E8).

Orfeo ed Euridice (Italian: [orˈfɛːo ed euriˈdiːtʃe]; French: Orphée et Eurydice; English: Orpheus and Eurydice) is an opera composed by Christoph Willibald Gluck, based on the myth of Orpheus and set to a libretto by Ranieri de' Calzabigi. It belongs to the genre of the azione teatrale, meaning an opera on a mythological subject with choruses and dancing. The piece was first performed at the Burgtheater in Vienna on 5 October 1762, in the presence of Empress Maria Theresa. Orfeo ed Euridice is the first of Gluck's "reform" operas, in which he attempted to replace the abstruse plots and overly complex music of opera seria with a "noble simplicity" in both the music and the drama.

The opera is the most popular of Gluck's works, and was one of the most influential on subsequent German operas. Variations on its plot—the underground rescue mission in which the hero must control, or conceal, his emotions—can be found in Mozart's The Magic Flute, Beethoven's Fidelio, and Wagner's Das Rheingold.

A roulade (from Old French roler, "to roll") is a type of music ornamentation. The term has been used with some variation in meaning. While the term has had some usage in instrumental music, it is most frequently used in the context of vocal music to refer to a florid embellishment of several musical notes sung on a single syllable. The word has sometimes been used interchangeably with the term coloratura to refer to any difficult vocal run requiring great vocal dexterity, or as a synonym for or a specific type of virtuosic melisma. The term roulade has also been used more specifically to refer to the ornamental practice of splitting up the melodic line of a piece of music into many smaller notes.

The term roulade has sometimes been defined as a vocal ornamental passage specifically limited to opera arias of the Classical and Romantic music periods. However, this limited definition is contradicted in the historical record, and other writers have used the term in contexts to other forms of music, such as oratorio, gospel music, and rock and roll.

Masonic music has been defined as "music used in connection with the ritual and social functions of freemasonry." Two major types of music used in masonic lodges are lodge songs, played to keyboard accompaniment before or after meetings, or during meals; and music written to accompany specific masonic ceremonies and events. Because the number 3 and the letter 'B' are of particular significance to freemasonry, music written in the keys of C minor or E flat major, which both involve 3 flats, (whose symbol '♭' resembles the lowercase letter 'b'), in their key signatures has been considered especially appropriate for masonic ceremonial music.

Although there had been earlier examples, like Jean-Philippe Rameau's opera Zoroastre (1749), whose librettist Louis de Cahusac was a Freemason, the masonic music of Wolfgang Amadeus Mozart is among the best-known of its kind. Mozart's opera The Magic Flute and his incidental music to Thamos, King of Egypt have masonic connections. Other openly masonic compisitions by Mozart include the Maurerische Trauermusik (Masonic Funeral Music) and a number of songs and cantatas.

The Theater auf der Wieden, also called the Freihaus-Theater auf der Wieden or the Wiednertheater, was a theater located in the then-suburban Wieden district of Vienna in the late 18th century. It existed for only 14 years (1787–1801), but during this time it was the venue for the premiere of no fewer than 350 theatrical works, of which the most celebrated was Mozart's opera The Magic Flute. During most of this period the director of the theater was Emanuel Schikaneder, remembered today as librettist and impresario of The Magic Flute.
