Query: ERROR - Harry Partch

Many people who are looking at this book probably already know about the life and works of microtonal composer and instrument inventor Harry Partch. (If you don't, you'd find great enjoyment in seeking this out!) I play on these instruments at the Harry Partch Instrumentarium at Montclair State University in NJ. How upsetting it was to immediately and excitedly turn to this book's section on Harry Partch's musical system to find the entire system misrepresented. The author says that his just intoned system starts on "C", when it really starts on "G". Therefore, all of the examples displayed are wrong and need to be transposed a fourth down. How infuriating!
