The question that Matthew Brown has set himself to answer is, basically, just how fundamental Schekerian analysis actually is. . . He seeks nothing less than a rigorous examination of the theory to see if it is logically consistent, sufficiently explanatory without being unneccessarily complex, and ultimately useful. . . . His range is enormous, and one cannot do adequate justice to what has been achieved here without detailed musical exemplification. The musical repertory ranges from early Baroque to the twentieth century.
