Compiled by one of Liebman’s protegees, saxohonist Matt Vashlishan, this is a pocket guide to he basics of saxophone playing, a kind of condensed version of Liebman’s historic treatise on the subject “Developing A Personal Saxophone Sound” (Dorn Publications). Able to be carried around easily, there is a very good review of all the required and advanced overtone exercises, considered the cornerstone of understanding saxophone principles.
