Ear Training: A Technique for Listening

I hate to do this but "a musician" is very incorrect. If you read the first line of the information the publisher says this book is designed for "classroom use". I used this text in college and now use it to teach my Advanced Placement Music Theory Course. Without a teacher (or the teachers edition) the book is essentially a lot of music examples with the first note(s) written in. The point of the book is to develop the ear. It is clearly not a self study book. (Of course, if one bothered to read the information on site one would know that).
