"It is by standing on the shoulder of giants." You may not find this book particularly readable (particularly if you're not mathematically inclined), and there's a fair amount of abstract philosophizing that can be difficult to practically reconnect to composition. That said, every chapter of this book presents radically new ideas, worked out with rigor and intention. Many of them have stood the test of time better than anyone could have imagined:
-His representation of musical states as states in a Markov Chain is similar to the probabilities derived in modern neural network representations of music
-His application of sieve theory is still in use
-His applications of game theory informed many other composers, and could be employed profitably today
-His critiques of the practicality of the Fourier Transform in composition are the same ones being used to justify Wavelet Transforms today almost 20 years after his death.
-This is where you'll find a full explanation of his GENDY method of synthesis and the various extensions, still in use today and available in programs such as CSound
I will say, of the reviewer who called Xenakis pretentious for inventing Greek words: Xenakis was Greek. That's like complaining Shakespeare coined the word "luggage". Highly intelligent speakers have every right to expand their native language if they feel it's inadequate to exposit their views.
