Hans Werner Henze (1 July 1926 – 27 October 2012) was a German composer. His large oeuvre is extremely varied in style, having been influenced by serialism, atonality, Neoclassicism, Italian music, Arabic music and jazz, as well as traditional schools of German composition. In particular, his stage works reflect "his consistent cultivation of music for the theatre throughout his life". Henze was also known for his political convictions. He left Germany for Italy in 1953 because of a perceived intolerance towards his leftist politics and homosexuality. Late in life he lived in the village of Marino in the central Italian region of Lazio, and in his final years still travelled extensively, in particular to Britain and Germany, as part of his work. An avowed Marxist and member of the Italian Communist Party, Henze produced compositions honoring Ho Chi Minh and Che Guevara. At the 1968 Hamburg premiere of his requiem for Che Guevara, titled Das Floß der Medusa (The Raft of Medusa), the placing of a red flag on the stage sparked a riot and the arrest of several people, including the librettist. Henze spent a year from 1969 to 1970 teaching in Cuba.

Der junge Lord (The Young Lord) is an opera in two acts by Hans Werner Henze to a German libretto by Ingeborg Bachmann, after Wilhelm Hauff's 1827 fairy tale "Der Affe als Mensch" (The Ape as Man) from Der Scheik von Alessandria und seine Sklaven (The Sheik of Alexandria and his Slaves). The style and plot owe much to Italian opera buffa, with the influence of Vincenzo Bellini and Gioachino Rossini noted. Andrew Porter has noted four distinct musical styles in the opera, corresponding to four different levels of characters: "neo-classical" style, for the townspeople; "neo-Straussian arioso", for Sir Edgar's entrance; a "wilder, more erratic" style, for the traveling circus; lyrical style, for Luise's love music. Robert Henderson has commented on the Brechtian nature of Bachmann and Henze's treatment of the story.

Elegy for Young Lovers (German: Elegie für junge Liebende) is an opera in three acts by Hans Werner Henze to an English libretto by W. H. Auden and Chester Kallman.

Undines (; also ondines) are a category of elemental beings associated with water, stemming from the alchemical writings of Paracelsus. Later writers developed the undine into a water nymph in its own right, and it continues to live in modern literature and art through such adaptations as Danish Hans Christian Andersen's 1837 "The Little Mermaid" and the 1811 novella Undine by Friedrich de la Motte Fouqué.
