question: Are Il re pastore and Giasone both operas?
answer: yes
context: Title: Il re pastore
  Passage: Il re pastore ("The Shepherd King") is an opera, K. 208, written by Wolfgang Amadeus Mozart to an Italian libretto by Metastasio, edited by Giambattista Varesco.  It is an opera seria.  The opera was first performed on 23 April 1775 in Salzburg, at the Palace of the Archbishop Count Hieronymus von Colloredo.
  Title: Gianni Schicchi discography
  Passage: This is a list of the recordings of Gianni Schicchi, the third of a group of three one-act operas by Giacomo Puccini collectively known as "Il trittico"; the other operas are "Il tabarro" and "Suor Angelica".  The three were premiered at the Metropolitan Opera on 14 December 1918, and for the next three years were always played together.  After 1921, however, Puccini agreed that the operas could be performed separately. " Gianni Schicchi" became the most popular and most frequently performed of the three, often paired with other works such as Maurice Ravel's "L'heure espagnole" and Richard Strauss's "Salome".
  Title: Terpsicore
  Passage: Terpsicore (HWV)(8b) is a prologue in the form of an opéra-ballet by George Frideric Handel.  Handel composed it in 1734 for a revision of his opera "Il pastor fido" which had first been presented in 1712.  The revision of "Il pastor fido" with "Terpsicore" as the prologue was first performed on 9 November 1734 at Covent Garden theatre in London, opening Handel's first season in that newly built theatre.  "Terpsicore" mixes dance along with solo and choral singing and was patterned after models in French operas, a particular source being "Les festes grecques et romaines" by Louis Fuzelier and Colin de Blamont, first presented in Paris in 1723.  The work featured the celebrated French dancer Marie Sallé as well as stars of Handel's Italian operas and was a success with audiences of the day.
  Title: Symphony, K. 208+102 (Mozart)
  Passage: The Symphony in C major "No. 52", K. 208+102, was composed by Wolfgang Amadeus Mozart in 1775.  The first two movements are from the opera "Il re pastore", K. 208, and the last movement, K. 102/213c, was composed separately.  The movements are played one after another without a break.
  Title: Il re pastore (libretto)
  Passage: Il re pastore is a 1751 Italian-language opera libretto written by Metastasio.  It was first set by Giuseppe Bonno in 1751, but best known today in the version by Gluck (1756) and the Il re pastore of Mozart (1775).
  Title: Catherine Dubosc
  Passage: Catherine Dubosc (born 12 March 1959) is a French soprano.  Born in Lille, she studied with Eric Tappy at the Opéra National de Lyon, before joining that company in 1985.  She is well known for her Mozart roles, but she has also sung operas written significantly earlier ("Giasone") and later ("Dialogues of the Carmelites").
  Title: Giasone
  Passage: Giasone ("Jason") is an opera in three acts and a prologue with music by Francesco Cavalli and a libretto by Giacinto Andrea Cicognini.  It was premiered at the Teatro San Cassiano, Venice on 5 January 1649, during carnival.  "Giasone" was "the single most popular opera of the 17th century".  The plot is loosely based on the story of Jason and the golden fleece, but the opera contains many comic elements too.
  Title: Jeli il pastore
  Passage: "Jeli the Shepherd" (it.  "Jeli il Pastore") is a short story written by Italian author Giovanni Verga as a part of his collection "The Life of the Fields""."
  Title: Tenore di grazia
  Passage: Tenore di grazia , also called leggero tenor ("graceful" and "light" tenor, respectively), is a lightweight, flexible tenor voice type.  The tenor roles written in the early 19th-century Italian operas are invariably leggero tenor roles, especially those by Rossini such as Lindoro in "L'italiana in Algeri", Don Ramiro in "La Cenerentola", and Almaviva in "Il barbiere di Siviglia"; and those by Bellini such as Gualtiero in "Il pirata", Elvino in "La sonnambula" and Arturo in "I puritani".  Many Donizetti roles, such as Nemorino in "L'elisir d'amore" and Ernesto in "Don Pasquale", Tonio in "La fille du régiment", are also "tenore di grazia" roles.  One of the most famous leggero tenors of that period was Giovanni Battista Rubini, for whom Bellini wrote nearly all his operas.
  Title: Calliroe
  Passage: The opera follows the usual pattern of "opera seria" of the time: "secco" recitative interlaced with "da capo" arias. Within this format Sacchini introduced strong dramatic music to suit the libretto: "stromentato" recitative is also used for extra dramatic effect, and the arias are sometimes interrupted by bursts of recitative.  Stylistically, the work is thought to anticipate Italian opera of the following decade, and in particular Mozart's "Il re pastore".
