His activities at Montepulciano and with the Munich Biennale, among others, have allowed him to exercise a strong influence on the wider understanding of contemporary music.

Stage Works

Henze’s immensely successful operas range from the 1951 Kafka radio opera, with its Trakl settings, Der Landarzt (The Country Doctor) to König Hirsch (King Stag), the Kleist Prinz von Homburg, Elegy for Young Lovers, with a libretto by W.H. Auden and Chester Kallmann, Der junge Lord (The Young Lord), The Bassarids, with Auden and Kallmann, based on Euripides, and We Come to the River and The English Cat, with texts by Edward Bond. Der verratene Meer (Treacherous Oceans), based on Yukio Mishima's Gogo no eiko, translated as The Sailor who fell out of Grace with the Sea, had its première in 1990, to be followed by Venus and Adonis, a fifteenth opera L'Upupa und der Triumph der Sohnesliebe (The Hoopoe and The Triumph of Filial Love), an Arabian fairy-tale, and, in 2007, Phaedra, a reworking of the tragedy of Phaedra and her stepson Hippolytus. Henze has also provided music for a series of ballets, with incidental music for the cinema and the theatre.

Orchestral Music

An exceptionally wide range of orchestral music includes ten symphonies, with a seventh drawing on Hölderlin and an eighth on Shakespeare's A Midsummer Night's Dream. He has written concertos for piano, for violin and, for Gary Karr, a double bass concerto, as well as a double concerto for oboe and harp for Heinz and Ursula Holliger. The third of his three violin concertos draws on Thomas Mann's Doktor Faustus.

Chamber & Instrumental Music

In addition to his string quartets Henze has written music for a variety of ensembles, including sonatas for violin, for viola and for flute and piano. Music for solo instruments includes the useful Lucy Escott Variations for harpsichord, works for various solo instruments, for violin, double bass, cello, marimba and trumpet, as well as a set of pieces for solo guitar, these last including his two Royal Winter Music, with movements based on characters from Shakespeare.

Vocal & Choral Music

Vocal and choral music by Henze is equally varied and remarkable, with Novae de infinito laudes (New Praises of the Infinite) with a text from Giordano Bruno, the Virgilian Muses of Sicily and the controversial Das Floss der ‘Medusa’ (The Raft of the Medusa), as well as the revolutionary El Cimarrón (The Fugitive).
