I haven't read it, yet, only did a quick search to see if I could fine the words "tonal center" somewhere. I think that concept is under-emphasized and resolves a bunch of common confusion about music. e.g. this post[1] that was on the front page a few weeks back in which the author did not understand what's the difference between C major and A minor.
