"An example of iconic realism in a musical composition utilizing instrumentation is Wagner’s mythical composition, The Ring of the Nibelungs. In this piece, Wagner represents various aspects of society through instrumental characterizations. As Tarasti affirms, 'the gods appear in the Ring not only as personifications of the elements of nature, for example, Loge as the god of fire, Donner the god of thunder etc, but also as a society, whose leader is Wotan.'  His use of contrasting instrumentation throughout his opus reveals an intense desire to illustrate corruption within his society. Many filmmakers choose to accompany the drama of their themes utilizing the nineteenth century Wagner music. An example of such intense films is Apocalypse Now, which illustrates the corruption associated with the Vietnam War" (Lakatos 78)
