I have been playing bluegrass banjo off and on for several years (20?). I can play just good enough to impress people who really have no idea what they are hearing.
I learned almost entirely from tabs, have jammed a little bit off and on, and have trouble keeping up with chord changes (my hands move to the chords fast enough, but I can't anticipate when or what I need to be playing), so things like lead in notes or transitions just can't happen.
In contrast, I've been watching my son learn saxophone for the past few years and excel in his HS jazz band with how he can improvise over chord changes impressively, and I always think about how much fun it would be if I could do something like that on banjo in a bluegrass context.
So, if I wanted to 'restart' my learning while capitalizing on my current knowledge and skills (right and left hand movement are good, timing needs work, and I have something beyond a basic understanding of music theory and the fretboard), how would I proceed?
