Of course, being a musical genius is a rare thing, and pretty much all of us on here could never qualify in that particular area, and I take no offence at all in anything you point out, we're just having a debate, and I must admit to be playing devil's advocate a little, but nevertheless, I still think there's an argument for those of us that [i]are[/i] theoretically illiterate, genius or not, that we have little or no need to understand theory to get as far as we want to go as musicians.
I'm not a pro, I'll never be a pro, and I'll never be in the position to have to read charts. I have however been in semi pro bands for years, and in one case had 10 days to learn a two hour set when depping for a band which I did no problem, by ear. Yes, I could have stood on stage, Thunderbird around my knees on stage with said metal band, with a stand and charts in front of me if I could read, but I'd have looked a total twit.
I'm perfectly at ease learning my way. I aint no Jaco, god I wish I was, but I'm too old to change my ways now. I'm off to learn a new song on my iPod for tomorrows rehearsal.
