In 1965, the American folklorist Alan Lomax set out on a mission: to view, code, catalogue and preserve the totality of the world’s dance traditions. Believing that dance carried otherwise inaccessible information about social structures, work practices and the history of human migration, Lomax and his collaborators gathered more than 250,000 feet of raw film footage and analyzed it using a new system of movement analysis. Lomax’s aims, however, went beyond the merely scientific. He hoped to use his ‘Choreometrics’ project (...) as the foundation for a universally available visual and textual atlas of human movement. This article explores how Lomax’s archival ambitions supported his efforts to enact a wholesale ‘recalibration of the human perceptual apparatus’ and situates Choreometrics at the nexus of new techniques of data-gathering and the cultural ferment of the 1960s.
