Query: Overpriced pistol target

Know that old saying, "you get what you pay for"? It's not always so.Copies of this book sell for $150 in places. That is ridiculous, seeing as it's less than an inch thick. It's supposed to cover centuries of music theory, yet each principle is explained vaguely and with few examples. If you want to get a really good step-by-step on Western music theory, take a look at Clough and Conley's "Basic Harmonic Progressions," which will give the reader a solid working knowledge of basic music theory ("basic" meaning the core of functional harmony). Unless you have a music class where this thin little book is required, stay far away from it. If I'm not able to sell this book back at the end of this year, I intend to take it to a target range and dispose of it properly. It will be the most expensive target I've ever bought.
