I've been practicing the a minor pentatonic for a while. It's the first one you're supposed to learn right? So I'm fairly condident that I can do all 5 positions without too much thinking. Then I started looking at all the scales that need to be learned and I was thinking how the heck do you memorize all that. Then I watched the video below. So I practiced the A minor pentatonic his way, well maybe a slight variation but I can now walk up the neck and be in A minor without too much thought. Then I was thinking, I wonder.... I have no idea what the notes are for the G minor pentatonic. But I applied his lesson, played the G note on the low E string and followed the exact same pattern and I was able to walk up the neck in G minor and have no idea as to what the notes were. I think this is the coolest lesson I have watched to date.
