when you play a minor pentatonic lick over the "relative" major chord progression it will sound fine but it have a bluesy sound. it will sound odd if you use it to accompany upbeat pop songs
This is only true if you start and stay within the minor. You are still playing the major scale, you're just starting from a different spot in the scale. This is why it's important to learn scales all the way across the fretboard. Having a two or three octave range with the scale gives you the flexibility to solo in key.
you can use the same shapes you learn for the minor pentatonic to play the major pentatonic scale its just the same shapes three frets lower.
Sorta. If you move the entire shape down, you're still playing a minor. If you start the pattern three frets down, but keep the shape in the same position, you'll be playing the relative major of that minor. The reason? The minor is the VI of some major scale. Three frets down brings you a step and a half, bringing you to the major key.
in general if you want a bluesy sound use the minor pentatonic and resolve to the A. if you want a major sound use the major pentatonic and resolve to the C.
If you're playing in A minor, or C, sure. Resolving to the A will sound funny if you're playing in B, though. What I think you're trying to express is that you should resolve to the root of the scale. I'd change that a bit, and say you always *can* resolve to the root of the scale. It's handy in a pinch, but you certainly don't have to.
the blue note for the Am blues scale is the bV which is Eb
There are other blue notes. I never use them but my lead guitar book suggests the II, III and VI of the A major scale which are B C# and F#. Don't ask me why.
You should learn those scales, and how they're built. Then you'll know why. Then you'd know where to hit the II III and VI of whatever key you're in.
Just so you know.
A major
A B C# D E F# G# A
What are the second, third, and sixth notes of that scale?
