This is kind of hard to explain; hopefully I can get my point across. I took a free trial lesson today from a local guitar/bass/piano teacher. He made a comment on how I fretted notes with the tips of my fingers, rather than using the "pads" which prohibited my left hand muting, because by using the "pads" of my fingers I could lay my fingers down across the fingerboard and mute more effectively. I started using the tips of my fingers to fret notes after reading an article on technique by Adamn Nitti at basslessons.com, and I usually muted notes with my with my picking hand, which was effective, but sometimes I would get undesirable harmonics. Overall, fretting notes feels much better to me when I use the tips of my fingers, so is there a way where I can mute the rest of my strings with my left hand without using the pads of my fingers?
