I hope this helps ... I'm not a fiddler, tho I love listening. As a singer, my first teacher was a concert tenor ... he tried to make me one. My next teacher was a basso profundo ... he tried to make me one. Today, I can sing well and I love it, and I have a VERY GOOD RANGE. My point is this, learn what you can from him, and then move on when you know it's time. And my age makes me add this, treasure the old ones, they've been there. Good luck!
