I have been playing acoustic guitar for agbout a year. I am now getting into scales im woundering which Scales are a must to learn? I started learning in the key of G. I was told That for that major Scale and finger pattern its moveable to other keys as long as I start on the root on the first two strings. Is this all I need to do is learn one postion or to learn all the postions. I have a hal leoneard scale finder book. Basically I want to be eventually good enough to be a lead guitarist and learn all skills needed to be a good guitarist.
Any imformation will be greatly appreciated.
