Another question from a rookie... When I play the main riff of the bassline to the the song Money, I do it the way I've seen it tabbed in more than source: G----4----------- D-----4---------- A-2----2----2-5-2 E--------2-5------ Here's the problem: after doing that a few times it starts to HURT. Specifically, I feel it in the muscle at the base of my thumb. After a while, it gets to be a distraction. I keep my thumb behind the neck and I have to move slightly to go from the 2nd to the 5th fret. So my question to those who have been playing a while is this: Is it normal to have this kind of discomfort when you've started playing riffs like the one above? Does it go away after a while with practice? Should I just keep playing 'til my fretting hand gets used to the movement or should I start playing open strings in place of the 5th fret notes? I want to do the song the way it's supposed to be played, but not if I feel like this.
