Here is an impressive passage from Richard Poirier:
The American writers I have been discussing have made the value of sound explicitly a subject of their work, and explicitly a resource for eccentricity. They suggest that the individual voice has in fact little else to depend on beyond the sounds it makes and, decidedly, those it refuses to make. [...] And yet, it should be apparent by now that in pressing their case the Americans simply SOUND different. They sound altogether less rhetorically embattled, less culturally ambitious than do any of these European cousins.
Richard Poirier, Poetry and Pragmatism (1992)
So it's all about becoming simple, wild, and... strange.
