I remember it like this: With no capo on you are at the root for the chord shape. So if you are in an e chord shape, there is no capo for e. If you move up a half with the capo you would be at an f with the e chord shape. If you move up a whole step from there with the capo you would be at a g with the e chord shape. Another whole step with the capo an a…another whole step a b… another half step a c (half steps are between b and c and e and f, all others are whole steps). I hope that helps.
I would memorize the major scale sequence (W,W,h,W,W,W,h) I remember it as major is 2 and 3 shared (meaning 2 whole steps and a break and 3 whole steps and a break). I remember Minor scale sequence (W,h,W,W,h,W,W) as minor is 1 and 2 and 2. It is a lot but it opens a new door.
