Let's take the pentatonic scale. This scale has 5 positions (5 boxes). I can play each box and i can imrovise on it.
But, how do i improvise on all the boxes? How do i traverse from one box to another?
This is common to see on videos, guys playing the pentatonic scale up and down the whole neck of the guitar...
My question is, how do i do that?
A friend of mine suggested to learn where the root note on each box is... Then traverse from one box to another by playing the next note from the root note you just pressed, to the other box's root note plus one note later...
Is this valid? And is this it? Or there's more?
