My question is similar to Leonin's. I have trouble getting my left-hand fingers to stretch so that each finger tip is just above each fret when I play standing up. When I try to play octaves on the first 7 frets, playing both notes simultaniously, I often have to bend my wrist at intensive, straining angles. When I don't do this, I get buzzes and a muddy sound, especially when playing slap. Any suggestions on how I can solve this? Would the exercises posted in "Left Hand Questions" work for my situation or could it be my technique?
