Now I got it. It's all there, clear, all terms defined, even some useful physical background revealed. It'll probably take another 14 years to get rid of all them bad habits, but many things I FELT before, I KNOW now (example: I used to feel uncomfortable about some things recommended in another method book, unfortunately the only one available in Czech language - just the same things are named in Art of... as beginners mistakes), so I'm convinced I'm on the right path. This is probably the most important point - the book is in accordance with what my ears, mouth, lungs etc. "think", and I can feel the improvements every day. Very satisfying. My teachers can now learn from me. So - if there's no chance for you to get a good teacher, buy this book. Period.
