I think theory is good for sure. If you care to learn it, do, i don't see how it can hinder you. But it is BS to say that anyone who doesn't learn theory is gonna be stuck in a three chords rut. Maybe someone who isn't adventurous or doesn't have an ear. It's not like you cant discover chords or chords progression without theory you know....its all there on the fretboard for you to discover. Eventually, theory or not, you will know what works with what and what sounds good with what. I don't know any theory. I mean, i know stuff but not by name. I guess i DO know theory technically but i cant explain any of it i just know what works together (i don't even know notes beyond the open strings, i never studied chord charts or anything of the like...but i DID pick up endless amount of song by ear, both on bass and guitar).
Definitely if you want to properly jam learning theory is a good thing, I can jam but if someone is switching keys left and right all the time, well...i probably can't follow without messing up a little here and there until i figure out what just happened (whereas with theory someone could tell me the key switch) but it is not necessary to write and compose music (personally i find jamming overrated...but then again my musical interests don't have much to do with improv and jamming) and I am fairly certain there's been a good amount of people who made millions in music who knew no or little theory. And i don't mean just ****** bands. Theory is only absolutely necessary if you have no ear whatsoever. And if you don't, you shouldn't be playing anyway.
That's my point and maybe (do I dare say his name

) Jeff Berlin's too.
No one is saying you need theory to play. Many people play to their deaths not knowing theory and having a great time doing it. Even have a following too.
I worked with a fellow who could not read or write. I would read his job instructions to him and he would work and do a fine job.
Supported his family by just speaking and hearing but, outside the job he had a hard time without someone helping him and if no one was there to help well...
Again it's what you want to do. Many people have even said here that they have even studied theory and still can't read or write as well as they may understand it.
H E double hockey sticks I studied English, I've been speaking it since I was a little guy and to this day I still have trouble with it and, it's my first language :scowl:
But if one wants to and I said
wants to advance in music like any language the best way is to study as much as you can. Involve a
good reputable teacher, get all info you can and learn, learn, learn
See in your own commits you say you can play and you use your ears to get along but there are things you have trouble with, like my not reading and writing friend. You still can't hear everything
"I can jam but if someone is switching keys left and right all the time, well...i probably can't follow without messing up a little here and there until i figure out what just happened " and
"(i don't even know notes beyond the open strings, i never studied chord charts or anything of the like...but i DID pick up endless amount of song by ear, both on bass and guitar)."
Those would be my first areas of study.
All I am saying is the more you learn the better you'll be.
