Document 2: Engelbert Humperdinck (composer): Engelbert Humperdinck (] ; 1 September 1854 – 27 September 1921) was a German composer, best known for his opera "Hansel and Gretel".
Document 3: Childe Rowland: "Childe Rowland" is a fairy tale, the most popular version written by Joseph Jacobs in his "English Fairy Tales", published in 1890. It was based on a Scottish ballad, which is why the text alternates between prose and rhyming stanzas. Joseph Jacobs called the King of Elfland's palace "the Dark Tower" in his version, an addition he made that was not part of the original ballad. This harks to Shakespeare's "King Lear" and Robert Browning's poem "Childe Roland to the Dark Tower Came," but neither of those references have any relation to the fairy tale.
Document 4: Le roi l'a dit: Le roi l'a dit ("The King Has Spoken") is an opéra comique in three acts by Léo Delibes to a French libretto by Edmond Gondinet. It is a lively comedy, remarkably requiring 14 singers – six men and eight women. The libretto had first been offered in 1871 to Offenbach; the title also went through various permutations ("Le Talon rouge", "Si le Roi le savait", "Le Roi le sait") before settling on its final name. The 1885 revival brought further modifications to the libretto.
Document 5: King René's Daughter: Kong Renés Datter ("King René’s Daughter") is a Danish verse drama written in 1845 by Henrik Hertz. It is a fictional account of the early life of Yolande of Lorraine, daughter of René of Anjou, in which she is depicted as a beautiful blind sixteen-year-old princess who lives in a protected garden paradise. The play was highly popular in the 19th century. It was translated into many languages, copied, parodied and adapted. The Russian adaptation by Vladimir Zotov was used as the basis for the 1892 opera "Iolanta", written by Tchaikovsky, with libretto by his brother Modest Ilyich Tchaikovsky.
Document 6: Michael Tippett: Sir Michael Kemp Tippett {'1': ", '2': ", '3': ", '4': "} (2 January 1905 – 8 January 1998) was an English composer who rose to prominence during and immediately after the Second World War. In his lifetime he was sometimes ranked with his contemporary Benjamin Britten as one of the leading British composers of the 20th century. Among his best-known works are the oratorio "A Child of Our Time", the orchestral "Fantasia Concertante on a Theme of Corelli", and the opera "The Midsummer Marriage".
Document 7: The Knot Garden: The Knot Garden is the third opera by composer Michael Tippett for which he wrote the original English libretto.

Document 8: A Midsummer Night's Dream (opera): A Midsummer Night's Dream, Op. 64, is an opera with music by Benjamin Britten and set to a libretto adapted by the composer and Peter Pears from William Shakespeare's play, "A Midsummer Night's Dream". It was premiered on 11 June 1960 at the Aldeburgh Festival, conducted by the composer and with set and costume designs by Carl Toms. Stylistically, the work is typical of Britten, with a highly individual sound-world – not strikingly dissonant or atonal, but replete with subtly atmospheric harmonies and tone painting. The role of Oberon was composed for the countertenor Alfred Deller. Atypically for Britten, the opera did not include a leading role for his partner Pears, who instead was given the comic drag role of Flute/Thisbe.
Document 9: Die Kluge: Die Kluge. Die Geschichte von dem König und der klugen Frau ("The Wise [Girl]. The Story of the King and the Wise Woman") is an opera in 12 scenes written by Carl Orff.

The composer also wrote the libretto, based on "Die Kluge Bauerntochter" ("The Peasant's Wise Daughter") from the Grimm's Fairy Tales. A performance lasts for about 90 minutes and is often paired with Orff's "Der Mond".
