The regionalization, commercialization, and subsequent diffusion of country music are examined in terms of the massification hypothesis. Each of the data sets examined suggests that the massification theorists were right in observing that the old patterns of cultural diversity along ethnic, regional, and even class lines are being destroyed or buried. But they have erred in their prediction of ever-increasing cultural homogeneity. While country music is increasingly embraced by mid-life, working and lower-middle class whites irrespective of regional origin, “easy listening” music is the preferred music in the same segment of the population. These data bring into question the assumption that social classes have distinct cultures and lead to the conjecture that these musical styles may represent convenient indicators of emerging culture classes.
