Threni: id est Lamentationes Jeremiae Prophetae, usually referred to simply as Threni, is a musical setting by Igor Stravinsky of verses from the Book of Lamentations in the Latin of the Vulgate, for solo singers, chorus and orchestra. It is important among Stravinsky's compositions as his first and longest completely dodecaphonic work, but is not often performed. It has been described as "austere" but also as a "culminating point" in his career as an artist, "important both spiritually and stylistically" and "the most ambitious and structurally the most complex" of all his religious compositions, and even "among Stravinsky's greatest works".
