I just completed the 30 Days to Play course. I have learned quite a bit about playing the guitar, and I now have some calluses on my finger tips. Plus, taking Tony's advice, I was able to get some lighter strings on my used guitar. It definitely helped! It's a challenge to get my fingers to cooperate with some of the chords, and I need more work on strumming and quickly & smoothly switching from one chord to another. All-in-All, I am seeing & hearing some improvement with my guitar journey. My wife also informed me that she thinks I'm improving little by little, as she hears me play from the other room. I'm looking forward to the next challenge in TAC.
