Hi all. I have noodled and played for years with no formal training only playing by ear. I started on guitar and have dibble dabbled with bass and played it mainly as an adult. One thing I see good players have as a true economy of motion where they lift fingers and have very little movement in their fretting hands. Are there exercises that can help me with this because when I play there are fingers flying everywhere?Also I have taught myself to play using 2 fingers rather than 3. Should I transition to that or work on improving the two? Do you have exercises you can recommend to also tighten up the speed and accuracy of the right hand? I don't truly alternate fingers when I play either. Thank you so much.
