For example, based purely on factor analysis, Lomax has shown statistical significance for how the traditional music of Georgian Russia is similar to (and may be a descendent from) that of Central Africa, and how the music of Patagonia is similar to that of the Inuit . And how dances with strong lateral knee movement correlate with cultures with a tradition of pottery (and potter's wheels), and how dances with narrow heel-to-toe movements correlate with societies whose main crop is planted in narrow rows (like rice). And how songstyles with large amounts of rasp in the male voice correlates with societies who raise boys to be independent rather than team players. And ones with a high degree of tonal blend (sounding as one) correlates with societies where women account for most of the food production. The list goes on. It's strong, romantic, arguable stuff.
