I mean just instinctively, in nearly complete, blissful, ignorance of the proper way of doing anything musically other than just finding a way to make nice sounds come out of your guitar? I'm like this, and always have been...for better or worse, which it often is. I find a way to match my guitar's tuning with my vocal range, but never really know what key I may be in to do it, it just sounds 'right' and I go with it. Of course, I never play with other people, so, again, it really doesn't matter, as long as it sounds 'right'. It's oddly liberating...and at the same time, cripplingly restrictive.
