a reliable guitarist told me that all u need to know fr playin lead is a good knowledge of major scales...so if i learn da major sclae in all da five positions n then be creative with those notes , will it b enuf ?? it sounds nice to me cuz i can change da key by movin up or down the frets.....am i right???
one more thing...there are millions of amazing guitarists in this world n surely all of em cant have absolute knowledge about all scales cuz from wat i can make out it needs a decent amount of intellect ( which i think i lack

) ..then how do these guys reach at a level where they can improvise n make one hell of a solo...surely there has to b a way out
i hope this is not misinterpreted as me tryin to take an easy way out ( i rlly work hard at guitarin) cuz i'm really curious to find a way through which i can improvise decently wen my buddy gives me any kinda chord progression n not js be stuck in a box...thnx
