pjw and acman, thank you for the valuable links. Pjw, I like your attitude in this matter and I agree with it. You already said pretty much all at the very beginning. Fro, your answer is of great value. It shows us on what we should pay attention on, when reading anything related to the skill of the professional and highly rated musician. Thank you for that.
