Sorry Guys, I'm sure this question has been posted before so I apologize for bringing it up again! I'm feeling confused about the minor pentatonic 5 shapes. The shapes themselves I just need to memorize, and I understand that using the low e string as a guide I can easily find where to start with the 1st shape, for example, the 5th fret on the E string for A minor pentatonic, etc. but staying in A minor how do I know where to play the other 4 shapes if I want to expand and play up the neck. I've hunted high and low but nobody seems to mention this. I have charts which show certain layouts, for example, I have one showing the 5 shapes in E minor, and it shows starting the 1st shape at the 12th fret, being obviously an E note, the 2nd shape starting on the 3rd fret, the 3rd shape starting on the 5th fret, the 4th shape starting on the 7th fret, and the 5th shape starting on the 10th fret. What is it that determines where the other 4 shapes are positioned after the 1st shape is placed on the root note along the E string? Sorry if this is a dumb question but I'm trying to get my head around why something happens, rather than just memorizing shapes, etc.
