Context paragraphs:
Montserrat Caballé: Montserrat Caballé (] ; born 12 April 1933) is a Spanish operatic soprano.  She has sung a wide variety of roles, but Caballé is best known as an exponent of the works of Verdi and of the bel canto repertoire, notably the works of Rossini, Bellini, and Donizetti.  She came to the attention of a much wider audience when she recorded at the request of the IOC in 1987 "Barcelona", a duet with Freddie Mercury, the lead singer of the British rock band Queen; the song was inspired by Caballé´s home city, later it was used as one of the two official theme songs for the 1992 Olympic Games.

Kalimotxo: Kalimotxo is a drink consisting of equal parts red wine and cola-based soft drink.  Although recently developed, it has become an icon of Basque culture.

Solita forma: In 19th-century Italian opera, la solita forma (literally conventional form or multipartite form or double aria) is the formal design of scenes found during the "bel canto" era of Rossini, Bellini, Donizetti up to the late operas of Verdi.  The English phrase—"multipartite form"—is most often used by American musicologist Philip Gossett, beginning with a 1974 essay, where referring to a general framework of melodramatic scene types, especially duets.  Each scene gradually progresses from an opening static lyric moment to a finale through several standard musical tempos and set pieces, gradually adding characters and adding or unraveling complexity in the plot.

Théâtre Louvois: The Théâtre Louvois or Salle Louvois was a theatre located at what is today 8 rue de Louvois in the 2nd arrondissement of Paris.  Inaugurated in 1791 and closed in 1825, it was used by the Théâtre-Italien from 20 March 1819 to 8 November 1825.  Gioachino Rossini became Director of Music on 1 December 1824.

Semirâma: Semirâma is an opera in three acts by Ottorino Respighi to a libretto by Alessandro Cerè based on Voltaire's 1748 play "Sémiramis", the same subject used for Rossini's Semiramide.  "Semirâma" premiered on 20 November 1910 at the Teatro Comunale in Bologna.  The première obtained a great success, with several calls for the composer and the singers.

Rossini (cocktail): The Rossini is a type of alcoholic mixed drink made with sweet sparkling wine (Prosecco) and puréed strawberries.  The cocktail is the most popular alternative to the classic Bellini.

Ivanhoé: Ivanhoé is an 1826 pastiche opera in three acts with music by Gioachino Rossini to a French-language libretto by Émile Deschamps and Gabriel-Gustave de Wailly, after Walter Scott's novel of the same name.  The music was adapted, with the composer's permission, by the music-publisher Antonio Pacini from Rossini's operas, namely "Semiramide", "La Cenerentola", "La gazza ladra", and "Tancredi" in order to introduce his music to Paris.  An examination of the score shows that Pacini also used music from "Bianca e Faliero", "Armida", "Maometto II", "Aureliano in Palmira", "Sigismondo", "Torvaldo e Dorliska", "Mosè in Egitto" and an amount of newly composed music including fanfares and the gallop that was later to become famous from its inclusion in "Guglielmo Tell".  The work was premiered on 15 September 1826, at the Odéon Theatre.

The Thieving Magpie (album): The Thieving Magpie (La Gazza Ladra) is a double live album by the British neo-progressive rock band Marillion.  It was named after the introductory piece of classical music the band used before coming on stage during the "Clutching at Straws" tour 1987–1988, the overture to Rossini's opera "La gazza ladra", which translates as "The Thieving Magpie".

Banda (opera): In opera, a banda (Italian for "band") refers to a musical ensemble (normally of wind instruments) which is used in addition to the main orchestra and plays the music which is actually heard by the characters in the opera.  A banda sul palco (band on the stage) was prominently used in Rossini's Neapolitan operas.  Verdi used the term "banda" to refer to a "banda sul palco", as in the score for "Rigoletto".  He used the term "banda interna" (internal band), to refer to a band which is still separate from the orchestra but heard from the off-stage wings.  The early scores of "La traviata" use a "banda interna".

Stabat Mater (Rossini): Stabat Mater is a work by Gioachino Rossini based on the traditional structure of the Stabat Mater for chorus and soloists.  Initially he used his own librettos and compositions for a portion of the work and, eventually, the remainder by Giovanni Tadolini, who composed six additional movements.  Rossini presented the completed work to Varela as his own.  It was composed late in his career after retiring from the composition of opera.  He began the work in 1831 but did not complete it until 1841.
