Both musical and literary criticism in the nineteenth century were engaged in aggressive projects of canon formation. Although their motives and methods differed in many particulars, the two projects were alike in seeking a centered aesthetic order as a counterweight to the increasingly decentered organization of modem life. To use the language of Max Weber, they sought to make the aesthetic the locus of the charismatic as the social became the locus of the bureaucratic. Given the era's social ideology, this aim required that the aesthetic, always dangerously proximate to the feminine, be a locus of masculine identity as well. The result was a mode of canonization focused more on persons than on texts and centered on the charisma of a single supreme-and supremely virile--figure.1 There was never much doubt about the identity of the supreme figure for either music or literature; the archetypal geniuses were going to be Beethoven and Shakespeare. But this selection introduced a slight asymmetry, which gives this article its topic. Because of Shakespeare's chronological priority, Beethoven could best be seen to equal Shakespeare if he could be seen to resemble Shakespeare. The resemblance, in turn, could best be justified if Beethoven, like so many nineteenth-century composers after him, had written music on Shakespearean topics. But this he perversely declined to do. Beethoven was an avid reader of Shakespeare, like most German intellectuals of his day, and he did consider writing an opera on Macbeth. But the opera remained unwritten, and there is no authorized Shakespearean composition in Beethoven's output. Some musical ideas intended for the Macbeth project may have found their way into the eerily atmospheric slow movement of the so-called Ghost Trio
