Whats a Virtuoso. WHat does it demand to become one. Does it require more than Almost perfection in playing (no one can reallly achieve perfection..even though i view some peoples playing as perfect.),what kind of attitude do you need, something that stands out from others?? Who are the bass virtuosos of our time besides Meyer, Rabbath, and Kar?. How do you know whose a virtuoso and that they are one??
