Yeah for real. It's so much easier playing while i'm sitting down. I started play guitar back in october and bass back in january, according to others i got rather good pretty fast. Well anyways yesterday i got bored and decided to play while standing up. I didn't think anything of it really but when i tried i soon realized i cannot play like this at all. I can not even play something simple, i feel all wierd and awkward, and i sound like hell. On bass i can slap really good while sitting down, but when i'm standing i can't do it at all. Whats the deal with this? Any advice?
