As said by Daniel Bareboim on the back cover of this work, "McGill deals with the different expressive means of sound, of styles and, perhaps most important of all for the practicing musician, the connection between attitude and aptitude. He understands perfectly that music is, after all, not a profession, but rather a way of life."   David McGill, a principal bassonist of the Chicago Symphony, the Cleveland Orchestra, Toronto Symphony and Tulsa Philharmonic, imparts  his wisdom and artistic vision throughout this work.
