light if you moveds your hand just right you could play that with your thumb rather than a barre but that might be a little harder.

and the way i understand it, if you using the correct notes its never wrong.

i wanted to put this in my original post but i didnt have time.

dimin you have an advatage over almost every other guitar player in the world. you already know and have taught others about muscles memory (even if you didnt know it). when a cop has to draw his gun he doesnt think hand to gun, pick up gun,raise gun, aim gun. it all happens automaticly. when you play and practice and practice the right ways you wont even have to think about what to do next youll do it automaticly. and since you already know the basics of how to teach your body, it should come easier to you.
