I'm sure that this has been addressed before, but I searched and couldn't find anything, so my apologies if the answer is out there and I just couldn't find it. I'm talking Southern Rock here, like Sweet Home Alabama, Can't You See, etc., and I'm talking about scale-based improvisation. And I'm really talking about that sound that is kind of blues and kind of country. What scales do you use to get that sound over this chord progression? Is there one scale that you play over the whole thing? Or do you need a different scale for each chord? Or do you use one scale over the D and C and a different scale over the G, or one scale over the D and another for the C and G? Major pentatonic? Minor pentatonic? Mixolydian? Thank you for any help!
