I'm having some trouble playing Eminor followed by Bminor in quick succession. The problem was a type of analysis-paralysis, where I wasn't sure in what order I should barre the chord, and then place my other fingers. I'm trying to change my mental mode, where I keep in mind a "root finger", which for Bminor is the middle finger which I first place on the correct string , and then place all other fingers in relation to it. This seems to help, since the task becomes (a) place root finger (b) naturally place other fingers after it.
