I got this for Christmas and while it looks interesting, it's certainly not a hold-your-hand type of book...

Anyone else have this book? How should I go about using it? I'd like to start from scratch so should I learn the scales it has from start to finish? Do I really have to learn ALL the scales? I mean, it seems like an enormous undertaking!

Just curious, for those who have this book, how do you use it? BTW, I'm trying to learn this stuff by myself. Teachers are few and far between.

Thanks.
