I am working thru a lesson in the blues section that is using powercords for a simple 12 bar (ie D5 to D6). My problem is when I stretch the pinky out for the D6 my ring finger follows my pinky even to the point of pressing down on whatever string it happens to be near when the pinky goes down. I can tuck tue ring finger or just plant it on one of the high strings but it cant be a good habit to build. I've looked on the interwebs to see if there are exercises to get some control but I'm not sure what works. Any suggestions?
