Toward a new music Book

Read this many years ago, but came across a reference to it earlier today in the forward, written by Max Matthews, to the very impressive looking Musimathics. I'm digging into my vague memory of what he wrote to paraphrase what he says: essentially, all you need to read to understand computer music is the two volumes of Musimathics (on the list!) and this book. I'm adding this back to my to re-read stack. ;~)
