Wow! Tons of info, but if you had never been exposed to music before, you're probably not anymore knowledgeable than when you began. It's difficult, if not impossible, to "explain" music to someone.
What I would have liked was more info on why Western music developed so much more differently than Eastern … why did we choose 1/2 steps instead 1/4 or 1/8 steps? Maybe we'll get some of this info in later readings.
