“What we find, then, is that Dante’s musical program embodies theological realities. Infernal sinners remain willfully rebellious. In life they broke away from the human community to pursue some good in vicious competition with the rest of the human race. Now, as a community, they fail to achieve concord. Like musical notes that remain independent, their retained individuality is ugly and broken. Repentant sinners in purgatory, on the other hand, now willfully submit their individuality to the community. They learn now what it is like to live as members of a body. And thus they erase their tendencies to erratic individualism, forcing their voices into the unison of the simple plainchant. But with the polyphonic hymns of Paradiso, we have not only concord but also a simultaneous expression of individuality: Dante gives us a vision of heaven as a million-part motet.”
