A German-born composer who firstbecame known for his operas. Using dissonant harmoniesand, for a time early in his career, melodiesbased on a twelve-tone series, Henze concentrateson the inner reality of his characters, in the mannerof earlier expressionist works (see EXPRESSIONISM).The formal structure of the operas tends to be strict,and occasionally there are direct allusions to oldermusical forms (for example, to a Bach chorale inThe Bassarids, itself a treatment of Euripides’ classicaldrama, The Bacchae). Henze’s operas includeKönig Hirsch (“Stag King”), Boulevard Solitude,Die Elegie für junge Liebende (“The Elegy forYoung Lovers”), and Der junge Lord (“The YoungLord”). In the 1950s Henze moved permanently toItaly. During the next decade he became a strongadmirer of revolutionary socialist principles, whichinspired the oratorio Das Floss der Medusa(“Medusa’s Raft”) of 1968, dedicated to Che Guevara,and his Sixth Symphony, written in Cuba,which quotes protest songs. He also composednumerous instrumental works, among them a Sonatafor strings, Fantasia for string orchestra (originally afilm score), Double Concerto for oboe, harp, andstring orchestra, Second Violin Concerto, the symphonicpoem Tristan for piano, tapes, and largeorchestra, Barcarola for orchestra, and nine symphonies.At least some of these instrumental worksare close to neoclassic in style. In both his small andlarge music theater pieces, such as El Cimarrón (forvocalist and three players) and We Come to the River(an opera calling for three stages, three orchestras,and featuring 111 roles), Henze continued to championthe underprivileged and oppressed and to attackfascism and militarism. His Symphony no. 9 (1997),an hour-long choral work, uses the story of sevenprisoners in a Nazi concentration camp who escapeand are sentenced to death by crucifixion.Herbert (hûr′bərt), Victor, 1859–1924.
