put it this way, you don't need a computer to tell you how to walk up five frets,. If one note sounds "off" play the one next to it. It IS that simple, you know the key and remember your chord tones, and you know what? sometimes the 'wrong' note sounds better.
At least that's what I tell myself hehe
I want you to find them yourself, teach a man to fish and all that.
Play along to Moondance for instance, so what if you hit some duds, just play along and you will get it
