So, I've been reading lots of players websites and credentials, and they all have so many names that they've studied under, played with, etc. It got me thinking... did these people have regular lessons with someone for X amount of time, or did they take one lesson and say they've studied with a certain person? We just had a jazz camp here, where Marvin Stamm was one of the head guys. I worked with him for 3 days, and had some one on one time, studied some things with him... could I officially say I've "Studied under Marvin Stamm"? Where is the line drawn on that kind of stuff... to me, it seems sketchy at points.
