In theater and music history, a burletta (Italian, meaning "little joke", sometimes burla or burlettina) is a brief comic opera.
 In eighteenth-century Italy, a burletta was the comic intermezzo between the acts of an "opera seria".
 The extended work Pergolesi's "La serva padrona" was also designated a "burletta" at its London premiere in 1750.
Theâtre de l'Étoile du Nord (Arabic: مسرح نجمة الشمال‎ ‎ ) also known as the North Star Theatre, is a theatre in the centre of Tunis, Tunisia.
 It is located at 41 Avenue de Farhat-Hached, near Avenue Habib Bourguiba since 26 February 2000; the theatrical production company was established on 29 February 1996.
 The premises of the theatre covers over 700 m2 , its great hall covering 400 m2 .
 Located in a former warehouse, it hosts concerts of all kind of music, literary meetings in French or Arabic and the theatrical presentations of the company of the Étoile du Nord.
 Said to be "as boho as Tunis gets", the theatre is popular with students and artists who meet in the alcohol-free cafe and its library.
 The theatre hosts around 160 events per year, including western style reggae, heavy metal and jazz groups performing and stand-up comedy.
Dramatic structure (also called Freytag's pyramid) is the structure of a dramatic work such as a play or film.
 Many scholars have analyzed dramatic structure, beginning with Aristotle in his "Poetics" (c. 335 BCE).
 This article focuses primarily on Gustav Freytag's analysis of ancient Greek and Shakespearean drama.
Il prigionier superbo ("The Proud Prisoner") is an "opera seria" in three acts composed by Giovanni Battista Pergolesi to a libretto attributed to Gennaro Antonio Federico and based on an earlier libretto by Francesco Silvani for Gasparini's opera, "La fede tradita e vendicata".
 It was premiered at the Teatro San Bartolomeo in Naples on 5 September 1733 and received further performances in October.
 The opera, with its labyrinthine plot involving the rivalry of Metalce (King of the Goths) and Viridate (Prince of Denmark) for the hand of Rosmene (a Norwegian princess whose father is Metalce's prisoner), soon sank into oblivion, but its comic intermezzo, "La serva padrona" (also by Pergolesi) was to achieve considerable success when performed on its own.
Die Huldigung der Künste ("The Homage of the Arts") is a dramatic poem written by Friedrich Schiller.
 It was his last completed dramatic work and premiered on 12 November 1804 in Weimar.
 Its final sentence, expressing Schiller's artistic credo, is "Denn aus der Kräfte schön vereintem Streben / Erhebt sich, wirkend, erst das wahre Leben".
Pimpinone, TWV 21:15, is a comic opera by the German composer Georg Philipp Telemann with a libretto by Johann Philipp Praetorius.
 Its full title is "Die Ungleiche Heirat zwischen Vespetta und Pimpinone oder Das herrsch-süchtige Camer Mägden" ("The Unequal Marriage Between Vespetta and Pimpinone or The Domineering Chambermaid").
 The work is described as a "Lustiges Zwischenspiel" ("comic intermezzo") in three parts.
 It was first performed at the Oper am Gänsemarkt in Hamburg on 27 September 1725 as light relief between the acts of Telemann's adaptation of Handel's opera seria "Tamerlano".
 "Pimpinone" was highly successful and pointed the way forward to later intermezzi, particularly Giovanni Battista Pergolesi's "La serva padrona".
Chamber opera is a designation for operas written to be performed with a chamber ensemble rather than a full orchestra.
 Early 20th century operas of this type include Paul Hindemith's "Cardillac" (1926).
 Earlier small-scale operas such as Pergolesi's "La serva padrona" (1733) are sometimes known as chamber operas.
Gennaro Antonio Federico (died Naples, 1744) was a Neapolitan poet and opera librettist.
 He is best remembered for his collaborations with G. B. Pergolesi including La serva padrona.
L'étoile is an opéra bouffe in three acts by Emmanuel Chabrier with a libretto by Eugène Leterrier and Albert Vanloo.
La serva padrona (The Servant Turned Mistress) is an opera buffa by Giovanni Battista Pergolesi (1710 – 1736) to a libretto by Gennaro Antonio Federico, after the play by Jacopo Angello Nelli.
 The opera is only 45 minutes long and was originally performed as an intermezzo between the acts of a larger serious opera.
 (The same libretto was set by Giovanni Paisiello in 1781.)
