Believe me, this is an easiest way to write tabs. You must be knowing that there are SIX strings in a guitar thats why we draw SIX lines on a paper. Point to be noted here is that we refer gutar's lower string (thinest one) as the FIRST TOP line in group of six on paper. With this information for the time being you can ignore the NAMEs given to these strings. So dont bother about ALPHABETS written on LEFT extrem of the lines. Sometimes and even more often people dont write those Alphabets.
So upto now you learned that you have SIX strings on paper out of which TOP one is the guitar's lowest one.
Now come to the numbers wriiten on strings. These numbers are actual the FRET number. You must have observed that NECK of you guitar has some vertical metal lines. These lines divide you guitar's neck into what we call FRET.
So if you see "X" written on "N" string on paper, if means that you have to PRESS that string number N at fret number X. This you can do using any fingure. Now when you are pressing, in that position only just STRIKE the same Nth string using your pluctrum in other hand. If you dont have pluctrum, just you your pinky fingure of right hand.
You read the paper tabs from LEFT to RIGHT. In that sequence keep reading the next number and its position and play that as explained above.
