Insights into Music Composition

First, at the price of this E-book I'd really expect some proper insights into music composition. I managed to scan through the text in less than five minutes. I'm so happy I didn't purchase the print book for which I'd have to pay extra for shipping.Second, nobody who's ever read or studied a few very basic notes on music composition is going to learn anything new in this text. I found more insights in Composition for dummies.
