This course reader is the evolving text for Music 420 at CCRMA. The December 2008 version (beta) can be ordered directly from CCRMA. However, note that I plan to "finish" this book next summer, so that the "September 2009 Edition" should be available (at about the same price) in the October 2009 time frame, and should be the latest version for a number of years.
Details of the December 2008 Edition (Beta):
The overall appearance of the book is similar to that of Mathematics of the Discrete Fourier Transform, but in a brown color scheme.
