Yesterday I downloaded major pentatonic scale lesson from audio-guitar-lessons.com....
I read that if you know the minor pentatonic scale, you know the major too (all you have to do is to shift it 2 frets down...).
Since I already know the minor pentatonic scale (all patterns-I'm not
boxed in
), do I have to learn major pentatonic scale?

I don't want to overload my brain with unnecessary things because it takes me a lot of time to remember all those patterns.
By the way: Is there any way to learn those other patterns faster?
Thanks for help!
