Between 1973 and 1979 Ruth and Jerry Mock self published a magazine focused on the classic guitar called Creative Guitar International (CGI). Aside from presenting a historical perspective, CGI has many articles about unique playing and practicing techniques, as well as suggested repetoire for solo and guitar ensembles. Although the first three volumes are not exceptionally diverse in scope, by the fifth issue (Spring 1975) there is an article by Colin Cooper, who was freelance writing during that time. The seventh issue (Fall 1975) has an article on the microtonal composer from Mexico, Julián Carrillo by John Ford and sheet music from a composition by Reed Maxson. I apologize for errors in grammar and format, some of which are beyond my technical ability to correct.
