learn power chords they are awsome
|-----| string 1
|-----|

|--4--|
|--4--|
|--2--| string 6
if u dont know how to read tabs im sure there is a excelant section on this site, basically each line is a string and the numbers indicate which fret to put your fingures on (kinda like co-ordinates)
this fingure shape ,wheather u want to fingure the fourth fret on the 5th and 4th strings with your third and pinky fingure or by baring (pressing 1 fingure over both the frets, this can be more difficult to get used to but i find it better) the fourth fet on both strings, this chord shape can be played anywhere on the neck but it is generally used un the 5 th and 6th string.
if u are playing electric guitar i personally wish i had learned to play these first because most rock songs a made up of power chords n i love the sound
use distortion or overdrive
hope that was some help
if any1 has any suggestion or wants 2 put me right on something say so, ive only been playin a few months
