Ok, I'm quite new to the guitar, I got one for christmas. A Martin D-28 (lucky me :P). I really enjoy Dave Matthews guitar, especially when he's teamed up with Tim Reynolds. I've been trying to learn some of their easier songs and I've gotten most of the fingering down for Crash. The basic intro chord looks something like this...

E --------------
B ---5---5------
G ---4---4------
D ---2---x------
A ---4---2------
E --------------

Ok so anyway when I try to play it, it sounds funny when I play the 1&6 strings along with it. But it doesn't have any x's... to mute. So does anyone know if the 1&6 strings should be muted, and if so... how? By palm or by left hand? Also in another song he has something like...

E---------------
B---------------
G101010-8-7-8---
D 8 8 8-8-5-5---
A---------------
E---------------

Or whatever... this isn't exact, just a basis for what I'm trying to get at. Would he mute the 1,2,5&6 strings, or would he just pick the middle 2 strings? I tried picking just the middle 2 with doing a full strum... and that's realllyy hard. I was thinking there must be some better way. But when I try to mute 1,2,5,& 6 I can't seem to be able to mute just those ones. So all in all, Is Dave just an extremely talented muter/strummer or is there something that I'm missing out on that might help.
