Hi, I am not sure if this was covered and forgive me if this is a repeat post but I am having some difficulties with some of the chords from Michaels book (which is a great buy by the way). Specifically the A7 chord on the 5th fret, I have no idea how to mute the A string with my thumb as my hands are a bit on the smaller side. I found another way to play the chord but it feels so unnatural.
I was wondering if anyone had the same issue and what they did. Thanks!
