I am pretty new to finger style, but am starting to get the hang of it. I have found that often if I am playing stuff on the D and G strings for a while the A will ring just from vibration of playing. It is starting to annoy me. How do you guys silence that string? I use my thumb on the E and then pluck the D and G with alternating index and middle fingers. What is the best way to silence that open A? Just move the thumb down? Seems easier said than done at this point. Thanks.
