Hi, Does anyone have any tips on how to keep your guitar steady whilst playing. I have a challenge that the neck tends to move forwards (out from the body) whilst I'm playing. I'm still very new (6 weeks in) and just moved onto playing 5 strings with Lisa, but these little things can really detract from playing, which is hard enough a these early stages. Is this about controlling the neck with the left hand, or about how you hold the body of the guitar with your right arm or a bit of both? Thanks in advance.
