Wow! I'm impressed at the muscle memory exercise and the results I'm getting in just a few short days. Like I said, the (very easy) chord progression I was working on (notice "was") was A D A E. Not a difficult progression, but only having played the guitar 3 weeks, it was challenging enough. I was struggling to keep up with a 45 bpm pace, and the play along music I had for this particular progression was at 55. Well, now after 3 days I'm able to keep up with the music and move it up to 65 reasonably well. It needs to be cleaned up a little, but it isn't bad. Wow!
Now that I've accomplished that goal, I've moved on to other progressions that I was a little slow on, such as G Em A D. No problem! I can keep up without any problems at all, so what I gained from training with Logan's muscle memory exercise transferred directly.
I mentioned the next challenging exercise is F C G - we'll see how that one goes, but I have tremendous confidence now. :)
Thank you for the encouragement!
