I dont think I realy get what your saying, but if you want to stay on beat its somtime easyer for me to tap my foot, count out loud like 1+2+3+4 or it may be easyer for you if you dont skip from a slow beat on your metronome to a fast beat. If you just started playing guitar and thats your first insterment then it always is hard at first. (Not saying that it wont be hard if you been playing for years) It just takes practice. :D
