Hillel Schwartz, in his October 22 paper about sounds ineffable and inexpressible in the church of Atotinilco in Mexico, playfully asked us to imagine “a taxonomy of sounds all around but not quite there.”  He suggested that we think about listening “octophonically”  — to sounds elusive, elusory, obscure, esoteric, delusive, allusive, aporic, and fantastic — and, to help us with this task, offered a chart printed out on “a sheet meant to be folded into a 3-orthoplex cross polytope.”  Folding the sheet into an octahedron — as in fact one audience member did, gifting the result to Schwartz — would put these eight categories into tighter adjacency than the 2D chart. The baroque character of the representation called attention to the epistemological origami sometimes needed to render representable that which is considered as operating just beyond apprehension. Simultaneously a parody of the simple attempt to count senses (see post of September 17) as well as a serious demonstration of the power of words actually to reach the putatively inexpressible, the chart should make scholars in sound studies think newly about what they hear and do not hear.
