Question: Is Sir Gawain and the Green Knight an Opera buffa?

full_context: Document 1: Le Chevalier à l'épée: Le Chevalier à l'épée ('The Knight with the Sword') is an earlier-thirteenth-century Old French romance, surviving in only one manuscript. It is the earliest romance to focus specifically on the Arthurian knight Sir Gawain and its plot is in some important respects similar to that of "Sir Gawain and the Green Knight". The poem presents a satirical or cynical take on ideas of chivalry.
Document 2: Spieloper: In the 19th century, Spieloper ('opera play') was understood to mean a light opera genre, developed from Singspiel. Works typical of the genre include those by Albert Lortzing, such as "Zar und Zimmermann", and Otto Nicolai's "The Merry Wives of Windsor". A key difference between Spieloper and Singspiel on the one hand, and opera buffa on the other, is that the two former genres contain spoken dialogues instead of recitatives, which is why Conradin Kreutzer's "Das Nachtlager in Granada" and Friedrich von Flotow's "Martha" do not belong to this genre.
Document 3: Sir Gawain and the Green Knight: Sir Gawain and the Green Knight (Middle English: "Sir Gawayn and þe Grene Knyȝt") is a late 14th-century Middle English chivalric romance. It is one of the best known Arthurian stories, with its plot combining two types of folklore motifs, the beheading game and the exchange of winnings. The Green Knight is interpreted by some as a representation of the Green Man of folklore and by others as an allusion to Christ. Written in stanzas of alliterative verse, each of which ends in a rhyming bob and wheel, it draws on Welsh, Irish, and English stories, as well as the French chivalric tradition. It is an important poem in the romance genre, which typically involves a hero who goes on a quest which tests his prowess, and it remains popular to this day in modern English renderings from J. R. R. Tolkien, Simon Armitage, and others, as well as through film and stage adaptations.
Document 4: Burletta: 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.
Document 5: Opera buffa: Opera buffa (] ; plural: "opere buffe"; Italian for "comic opera") is a genre of opera. It was first used as an informal description of Italian comic operas variously classified by their authors as "commedia in musica", "commedia per musica", "dramma bernesco", "dramma comico", "divertimento giocoso".
Document 6: Farsa: Farsa (Italian, literally: "farce", plural: "farse") is a genre of opera, associated with Venice in the late 18th and early 19th centuries. It is also sometimes called "farsetta".
Document 7: Operetta film: Operetta films (German: Operettenfilm) are a genre of musical films associated with, but not exclusive to, German language cinema. The genre began in the late 1920s, but its roots stretch back into the tradition of nineteenth century Viennese operettas.
Document 8: Giulio Sabino: The opera, staged in six or seven European countries at the end of the 18th century, was the subject of a parody in Antonio Salieri's 1786 work "Prima la musica e poi le parole".
Document 9: Lady Bertilak: Lady Bertilak is a character in the medieval poem "Sir Gawain and the Green Knight". She is ordered by her husband, the Green Knight, or Lord Bertilak, to test Sir Gawain's purity.
Document 10: 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".
Document 11: Gawain and the Green Knight (film): Gawain and the Green Knight is a 1973 film directed by Stephen Weeks, and starring Murray Head as Gawain and Nigel Green in his final theatrical film as the Green Knight. The story is based on the medieval English tale "Sir Gawain and the Green Knight".
Document 12: Green Knight: The Green Knight is a character in the 14th-century Arthurian poem "Sir Gawain and the Green Knight" and the related work "The Greene Knight". His true name is revealed to be Bercilak de Hautdesert in "Sir Gawain", while "The Greene Knight" names him "Bredbeddle". The Green Knight later appears as one of Arthur's greatest champions in the fragmentary ballad "King Arthur and King Cornwall", again under the name "Bredbeddle". In "Sir Gawain and the Green Knight", Bercilak is transformed into the Green Knight by Morgan le Fay, a traditional adversary of King Arthur, in order to test his court. In "The Green Knight" he is transformed by a different woman for the same purpose. In both stories he sends his wife to seduce Gawain as a further test. "King Arthur and King Cornwall" portrays him as an exorcist and one of the most powerful knights in Arthur's court.
Document 13: King Arthur and King Cornwall: "King Arthur and King Cornwall" is an English ballad surviving in fragmentary form in the 17th-century Percy Folio manuscript. An Arthurian story, it was collected by Francis James Child as Child Ballad 30. Unlike other Child Ballads, but like the Arthurian "The Boy and the Mantle" and "The Marriage of Sir Gawain", it is not a folk ballad but a professional minstrel's song. It is notable for containing the Green Knight, a character known from the medieval poems "The Greene Knight" and the more famous "Sir Gawain and the Green Knight"; he appears as "Bredbeddle", the character's name in "The Greene Knight".
Document 14: Sword of the Valiant: Sword of the Valiant: The Legend of Sir Gawain and the Green Knight is a 1984 dramatic fantasy film starring Miles O'Keeffe, Trevor Howard, Lila Kedrova, Cyrielle Clair, Leigh Lawson, Peter Cushing, and Sean Connery. The film is loosely based on the poem "Sir Gawain and the Green Knight", written in the late 14th century, but the narrative differs substantially. This was the second time director Stephen Weeks had adapted the traditional tale into a movie. His first try was "Gawain and the Green Knight", starring singer Murray Head, and released in 1973.
Document 15: Operetta: Operetta is a genre of light opera, "light" in terms both of music and subject matter.
