hey guys. quick question on scales. Say you take some major scale and start it with its root on the A string, usually when I get to the B string I just kind of shift the scale down the neck a half step, but in some keys, it doesn't always work, are there are rules on this or could someone help me out? Thanks in advance.
Depends on what chords you're playing over, and how well the notes from the "shifted scale" work over them.
