A cursory summary, courtesy of Google Scholar, reveals in excess of 9,000 academic publications devoted to the marginal and highly localised phenomenon of glossolalia, or speaking in tongues.  The same method, when turned towards joint speech, collective speech, choral speech, or synchronous speech, shows less than 800 academic publications.  There is an order of magnitude less in the observational and scientific canon about the widespread practice of joint speech that stitches together our rituals, our liturgies, our secular ceremonies, and our school practices than is to be found in the study of an isolated phenomenon that few of us will ever encounter.

How heartening then to see some careful documentation of chant in a specific situation. Kamal Moghith has recently published a book entitled “Chants of the Egyptian Revolution“.  In it, he collates chants from different eras, as part of different and successive political movements.  He considers the relation between the concerns of specific groups, such as professors, and the larger social currents within which these aspirations become enfolded.  

So far I have only been able to find announcement of the launch.  I hope a translation may some day appear.  We need more observation, careful documentation, and to integrate these observations in our discourse of our singular and collective selves.
