Let me preface this by saying I am an absolute beginner (I recently got quite a reality check with that Billie Jean lesson). So, I imagine it’s not crucial to worry too much about thumb positioning at this point. That said, I would like to try to get good fundamentals ingrained early if possible. I’m wondering about where to rest my thumb on my plucking hand (I’m playing a 4-string).
When I first started I would rest it on a pickup when playing the E and A strings, on the E string when playing the D string, and on the A string when playing the G string (with the knuckle of my thumb against the E string to mute it).
With that Billie Jean lesson, though, I started to wonder if it would be more efficient to just rest on the pickup when playing the E and A, and then rest on the A when playing the D and G.
Again, I’m sure this is farther ahead than I need to worry about, but I am curious. Thanks!
