Let's begin by consulting the Cantometric database. While I didn't define "Shouted Hocket" (or any of the the other style families) exclusively in Cantometric terms, we can get a rough approximation by looking for four specific traits: interlocked vocal organization; short or very short phrase lengths; one or two repeated phrases; and forceful to very forceful accent. A query for all performances exhibiting all four traits produces the following set of hits: the Ju'hoansi Bushmen tcoqma ritual we've already heard; 3 Mbuti Pygmy performances; 5 Inuit performances; 1 from Kamchatka (Siberia); 2 Yukaghir (Siberia); 1 Hupa (North American); 1 Motilon (South American); 1 Amahuaca (S. American); 1 Shuar (Jivaro, S. Amer.) 2 Ata Krowe (Flores, Indonesia); 1 Ajie (Melanesia); 2 Biami (New Guinea); the Bisorio performance we've heard (N. Guinea); 4 Dani, including the example we've heard (N. Guinea); 2 Huli, including he example we've heard (N. Guinea); 1 Yali (N. Guinea); 1 Hanunoo (Phillipines); 1 Georgian (Caucasus, Asia); 1 Russian; 1 Hungarian Gypsy; 1 Village India; and several African groups: Bundo, Mbala, Ndongo, Lese, Anaguta, Forest Bira, Toma, Meru, Tandroy, Masai, Samburu, Pondo, Wodabe Fulani, Hamar, Tuareg, Ajuran, Dorze, Gamo, Konso and Gio.
Aside from the Russian, Gypsy and Village Indian examples, which apparently don't fit, all the others could in fact be good candidates for the style area in question, which, according to the phylogenetic map, would be very broadly distributed among tribal groups in Africa, Melanesia, New Guinea, Siberia, and the Americas, notably Inuit and California. The South American examples may also be meaningful, as I explain in my essay, though the connection is by no means obvious. The Balinese Monkey Chant is not on the list, probably because the elements of shouted hocket are embedded in a more complex structure.
The above query is comprehensive, in other words it is as significant for the very large number of groups not represented as those which are, telling us, in fact, that the great majority of the worlds peoples very likely do not have musical traditions characterized by shouted hocket. Which makes those who do all the more interesting. Examination of the list gives us, I would think, a pretty good sense of both the strengths and weaknesses of the Cantometric approach. A well designed query, based on a good sense of what to look for, can provide a very useful overview of the stylistic terrain, an excellent starting point for further investigation. It will almost always, however, contain certain things that probably don't fit and omit others that do. This is to be expected from a heuristic system, necessarily provisional and preparatory.
