Question: Are Dafne and The Rite of Spring both operas? 

full_context: Document 1: The Rite of Spring (MacMillan): The Rite of Spring is a one-act ballet created by Kenneth MacMillan in 1962 for the Royal Ballet. The music is Igor Stravinsky's "The Rite of Spring" (1913). The conductor was Colin Davis; the designs were by Sidney Nolan.
Document 2: Jacopo Corsi: Jacopo Corsi (17 July 1561 – 29 December 1602) was an Italian composer of the late Renaissance and early Baroque and one of Florence's leading patrons of the arts, after only the Medicis. His best-known work is "Dafne" (1597/98), whose score he wrote in collaboration with Jacopo Peri. Six fragments of the score have survived, two by Corsi and four by Peri. The libretto, by Ottavio Rinuccini, has survived intact. Despite priority quibbles at the time, Dafne is generally accepted as the first opera.
Document 3: Der Freischütz: Der Freischütz , Op. 77, J. 277, (usually translated as "The Marksman" or "The Freeshooter") is a German opera with spoken dialogue in three acts by Carl Maria von Weber with a libretto by Friedrich Kind. It premiered on 18 June 1821 at the Schauspielhaus Berlin. It is considered the first important German Romantic opera, especially in its national identity and stark emotionality.
Document 4: Agon (ballet): Agon (1957) is a ballet for twelve dancers, with music by Igor Stravinsky and choreography by George Balanchine. Composition began in December 1953 but was interrupted the next year; work was resumed in 1956 and concluded on April 27, 1957; the music was first performed on June 17, 1957, in Los Angeles conducted by Robert Craft, while the first stage performance was given by the New York City Ballet on December 1, 1957, at the City Center of Music and Drama, New York . The composition's long gestation period covers an interesting juncture in Stravinsky's composing career, in which he moved from a diatonic musical language to one based on twelve-tone technique; the music of the ballet thus demonstrates a unique symbiosis of musical idioms. The ballet has no story, but consists of a series of dance movements in which various groups of dancers interact in pairs, trios, quartets, etc. A number of the movements are based on 17th-century French court dances – saraband, galliard and bransle. It was danced as part of City Ballet's 1982 Stravinsky Centennial Celebration.
Document 5: Petrushka (ballet): Petrushka (French: "Pétrouchka" ; Russian: "Петрушка" ) is a ballet burlesque in four scenes. It was composed in 1910–11 and revised in 1947. Igor Stravinsky composed the music, and, with Alexandre Benois, fashioned the libretto. Michel Fokine choreographed the ballet; Benois designed the sets and costumes. "Petrushka" was first performed by Sergei Diaghilev's Ballets Russes at the Théâtre du Châtelet in Paris on 13 June 1911. Vaslav Nijinsky portrayed Petrushka with Tamara Karsavina as the Ballerina. Alexander Orlov portrayed the Moor, and Enrico Cecchetti the Charlatan.
Document 6: Jacopo Peri: Jacopo Peri (Zazzerino) (20 August 156112 August 1633) was an Italian composer and singer of the transitional period between the Renaissance and Baroque styles, and is often called the inventor of opera. He wrote the first work to be called an opera today, "Dafne" (around 1597), and also the first opera to have survived to the present day, "Euridice" (1600).
Document 7: The Rite of Spring (The Bad Plus album): The Rite of Spring is a 2014 album by jazz trio The Bad Plus. It is the group's ninth studio album. It is an interpretation of the Igor Stravinsky orchestral composition.
Document 8: 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 9: The Firebird: The Firebird (French: "L'Oiseau de feu" ; Russian: Жар-птица , "Zhar-ptitsa") is a ballet by the Russian composer Igor Stravinsky, written for the 1910 Paris season of Sergei Diaghilev's Ballets Russes, with choreography by Michel Fokine. The scenario by Alexandre Benois and Fokine is based on Russian fairy tales of the magical glowing bird that can be both a blessing and a curse to its owner. Premiered in Paris on 25 June 1910, the work was an instant success with both audience and critics.
Document 10: Igor Stravinsky: Igor Fyodorovich Stravinsky (sometimes spelled "Strawinski", "Strawinsky", or "Stravinskii"; Ukrainian: І́гор Фе́дорович Страві́нський , ] ;Russian: И́горь Фёдорович Страви́нский , "Igorʹ Fëdorovič Stravinskij"; ] ; 17 June [O.S. 5 June] 1882 6 April 1971) was a Russian Empire-born composer, pianist, and conductor. He is widely considered one of the most important and influential composers of the 20th century.
Document 11: Heinrich Schütz: Heinrich Schütz (] ; 18 October [O.S. 8 October] 1585 – 6 November 1672) was a German composer and organist, generally regarded as the most important German composer before Johann Sebastian Bach and often considered to be one of the most important composers of the 17th century. He wrote what is traditionally considered to be the first German opera, "Dafne", performed at Torgau in 1627, the music of which has since been lost.
Document 12: L'Orfeo: L'Orfeo (SV 318) (] ), sometimes called La favola d'Orfeo ] , is a late Renaissance/early Baroque "favola in musica", or opera, by Claudio Monteverdi, with a libretto by Alessandro Striggio. It is based on the Greek legend of Orpheus, and tells the story of his descent to Hades and his fruitless attempt to bring his dead bride Eurydice back to the living world. It was written in 1607 for a court performance during the annual Carnival at Mantua. While Jacopo Peri's "Dafne" is generally recognised as the first work in the opera genre, and the earliest surviving opera is Peri's "Euridice", "L'Orfeo" is the earliest that is still regularly performed.
Document 13: Dafne: Dafne is the earliest known work that, by modern standards, could be considered an opera. The libretto by Ottavio Rinuccini survives complete; the mostly-lost music was completed by Jacopo Peri, but at least two of the six surviving fragments are by Jacopo Corsi. "Dafne" was first performed during Carnival of 1598 (1597 old style) at the Palazzo Corsi.
Document 14: Dafne (Opitz-Schütz): Die Dafne (1627) to a libretto by Martin Opitz (which survives), and music by Heinrich Schütz (which is lost), has traditionally been regarded as the first German opera, though it has also been proposed more recently that it was in fact a spoken drama with inserted song and ballet numbers.
Document 15: The Rite of Spring: The Rite of Spring (French: Le Sacre du printemps ; Весна священная, "Vesna svyashchennaya", "sacred spring" ) is a ballet and orchestral concert work by the Russian composer Igor Stravinsky. It was written for the 1913 Paris season of Sergei Diaghilev's Ballets Russes company; the original choreography was by Vaslav Nijinsky, with stage designs and costumes by Nicholas Roerich. When first performed, at the Théâtre des Champs-Élysées on 29 May 1913, the avant-garde nature of the music and choreography caused a sensation and a near-riot in the audience. Although designed as a work for the stage, with specific passages accompanying characters and action, the music achieved equal if not greater recognition as a concert piece, and is widely considered to be one of the most influential musical works of the 20th century.
