Note: Mnong Gar of Vietnam have slash and burn agriculture. When they get together and play instruments, it's every man for himself. No polyphony. Arensberg: They have networks but not stable groups. Lomax: Rice cultures of Philippines have little coordination musically. Gongs aren't even tuned to each other. Arensberg: Dionysian cultures are networking, come together infrequently and have big blowout when they do. Lomax: Micronesia has striking polyphony. Arensberg: Reef fishers have endless collaboration. Arensberg's approach receives a lot of corroboration. Scales are crude but do represent a universal range of variations. We can say, "Probably polyphonic people are like this." Alan Lomax: Cantometrics is on a regional level. So is Murdock. Extreme situations, pygmies, Western Europeans, yield beautiful results. Where results are vague, we need more musical and cultural evidence. Key variables include seamless group versus diffuse group, male-female dimension, structural dimension. Music as symbolization. Alan Lomax: "If it's not that, what is it?" Arensberg: Anthropologists will call some results (complexity associated with orchestras) truisms. But it is worth a try. What are the variations in the human experience that will explain man's activities? Network people turn out to have no polyphony. Mnong Gar have no special children's music. Children are completely integrated into adult activities. Compare to backwoods of Central Europe. Most music is made by young people. Choruses are young men. Older men stop making music. Among Africans music is made by young men and women. Old people dance.
