For most of my 58 years I've spent at least three hours a week doing communal acapella singing of word-rich and vowel-rich music, in the form of Christian hymns, following a tradition that my ancestors have observed at least since the early Byzantine empire. Mr. Eno is to be commended for his recent discovery that there's some value in that. We don't make the same claims as he made about good figure and heightened sexual attractiveness, but we definitely agree with him that the experience is life-enhancing for the individual and the community. However, we prefer the eight modes of the Octoechos over "the basic chords of blues and rock and country music."
