Kasperow > Relax...yep....that is the ticket. Some guys even barely touch the strings. I'm a little more heavy handed in some ways (I love a deep and digging bend) but being able to let physics do the work and not your hand is really important.
I've taught a coupla people in my day and I noticed that to a person, they all wanted to give the neck a death grip. I'd tell them to do an experiment: Hover your hand over the low E string (second fret) but don't touch it. Start picking the open string. Then slowly lower your finger on to the string (which will flat out at first) but continue to apply very light pressure only until the string rings true. Then stop. You will realize how little pressure it takes to make the string ring.
Response by Kasperow:
I just tried this, and it's true. It doesn't take a lot of pressure to fret a note cleanly. I'm starting to improve a lot in that aspect, which is actually very important, as it means I waste less energy, which by extent means that I'll be able to go on for a lot longer than if I play like I used to (which often got pretty close to "choke the guitar to death"...)
Yeah...there's books on the subject. Of course, knowing to relax and being able to relax are two different things. Jamey Andreas writes about not just the 'death grip' but everything...leg tension, shoulder tension, gritting teeth and on and on.
Jeff65 - I had to chuckle a little about your tip to hum notes. I started doing this just hours ago (yesterday's practice session) - a few hours before your post. Great minds..! ;)
"It takes a lot of devotion and work, or maybe I should say play, because if you love it, that's what it amounts to. I haven't found any shortcuts, and I've been looking for a long time."
