scales are road maps. Everything we do comes from a scale of sorts, in multiple positions on the fret board. Even though we don't know any and refuse to learn them and maybe feel they are not necessary. Sit in front of a skilled player and play some stuff, they will tell you and SHOW you what scale you are playing out of and why the dots are connected. And you will say.."Ahhh, no wonder it all works and flows nicely". Ever wonder why we can't expand on our solo's and continue to play the exact same things and positions week after week , month after month, year after year ? Knowing 3 or 4 root scale variants up and down the fretboard and the chord shapes they form is like a 10 to the 3rd power of math ! And it doesn't take long, just some regular brief seat time. 5 min a day. Ever get lost driving in a 200 + home neighborhood with streets going every which way , but only ONE WAY OUT ? There are many of us guitar players who get stuck playing out of a single root position. It doesn't have to be that way !
