I didn’t check your profile, so I don’t know where you live, so I’m not sure what you have access to, music-wise. But here’s my two cents:
What is your actual goal? To get deeper into music, to play more, to have a piece of paper that shows you completed a course of study? This is posted in the bass guitar section, so my assumption is that you’re not pursuing a classical performance path, and since you’ve had a career prior that you’re not getting a degree to pursue a teaching position. If those assumptions are incorrect, my apologies.
My experience is only my experience, but after involvement in pursuing Music Performance degrees in both a small liberal arts university and Berklee, I can without equivocation say that the most progress I made as a player was studying privately with a great teacher, Joe Solomon. He not only was able to instruct in musical fundamentals of physical approach (technique), understanding (theory), and hearing with clarity (ear training), he was able to do that one on one, as opposed to a class room experience. That means I didn’t move on until I achieved 100% of what information I was receiving, rather than receiving some kind of pass/fail or numerically scaled grade that determined if I moved on at the end of a semester. Classroom study tends to move at the pace of the middle of the group; if you understand quickly you don’t get to move on, if you have trouble comprehending or executing you don’t get to slow down till you DO get it. You just get the B or C and move on.
But all that really is contingent on having a GREAT teacher and being in an environment with a lot of other musicians with which to play. One thing that Berklee did provide was a huge opportunity to play ALL the time, both in the ensembles that were part of the academic program and in after school sessions with other students. Not all universities have a large number of performing ensembles, a lot of the smaller ones just have the big band and that’s it. No repertory ensembles, no small groups doing the music of specific composers. Plus, like a lot of guitarists who came to Berklee right out of high school, you may not get to play in any ensembles and get stuck in remedial instrumental classes.
I did get to hang around the program at the New School, I would be part of the professional rhythm sections hired to play for students sophomore juries; and it pretty much followed the same pattern as Berklee…
