Thanks for the nice welcome. And you couldn't be more correct, it is difficult demanding and long- especially for improvisational (jazz) musicians who need to cultivate a conversational command of their instrument. Charlie Parker perhaps the greatest genius of modern jazz was said to have practiced 15-20 hours a day for years to achieve his incredible virtuosity. Unfortunately he was fueled by not only his burning desire but also by narcotics. Which eventually led to his early demise (He was 34 but coroner reports put him at 55) Thanks for the email-
