This site takes us to R. Murray Schafer's site, where he has written a vital book & that book is about The Tuning of the World, how to repair our depleted soundscape; how to map the terrain of sound. This investigation - a lifelong one on the part of this Canadian Composer - has led to teams of volunteers, maintaining sonic maps of the terrain we're losing second by second.
The Tuning of the World has been praised by specialists in many disciplines as a work which will have far-reaching effects on the future.
'Schafer's book is a consciousness-expanding experience.'  
Carl Sagan
'Today it must have top priority.'
Marshall McLuhan
'Schafer is a very original Canadian... The Tuning of the World is an unusual sensory experience. The original sections will raise your consciousness of the soundscape to a level of sensitivity you never experienced before.'
New York Times
'This is an extraordinary book, fascinating to read and far-reaching in its visionary projection.'
Publisher's Weekly
