I started practicing slap and pop tonight, and the problem is when I pop, I have to raise my forearm off of the bass body. When I do that, my neck heavy bass slides and I have to hold it up with my left hand. This happens in both the sitting and standing positions. Needless to say this makes playing very difficult. Normally when playing with two fingers, my right forearm holds the bass steady so I don't have this problem otherwise. It's only when I try to pop. Does this happen to anyone else and what should I do about it? EDIT: Is the solution simply to learn to pop without lifting my forearm off the bass? Probably. Any recommendations for how exactly to perform the technique of popping with my arm resting on the bass?
