I've looked at that book before, and while I agree that it's probably worth reading it sure doesn't answer all the questions. It just talks about voice leading and gives scientific explanations for why the 18th century rules of part writing reliably turn out pleasing music. It doesn't account for all the music that satisfies listeners somehow even while violating some of those conventions. Nor does it cover anything aside from tonality, from what I remember.
