...and that's key, to summarize what I think Superhuman is saying, is to let it flow. I think that knowing scales and theory is very important because you do need the roadmap to know where you're going but the reality is, you still have to do something with it. Guitar playing is not at all about knowing information. It's about getting out what you feel. Communicating, even if to only yourself, what you feel musically inside. Scales and theory helps you get there but it is a means to an end.

I think to hidden's issue, it's almost a case of trying too hard. Like the 'had a coupla beers and perfected it' part. Got just a little loose and it came. I don't advocate drinking and playing (a 'PUI'?) but it does point out that music is a flow you run with and not fight against.
