I'm a beginner guitar player and I was trying to play this tab. but I don't understand it. which strings to bar? Why the name of strings are not as normal and what does that 3/2 means ?
I am confused by the "SLIDEE" written down the side, but aside from that, I would personally play this with my thumb over the top fretting the 3rd fret on the low E string, then ring finger (third finger) on the 5th fret of the A string, pinky (fourth finger) on the 5th fret of D, and middle finger (second) on the 4th fret of G.
Most people don't fret with their thumb so you would instead reach up with your index (first finger) to fret the 3rd fret of the low E. All of your fretting fingers should be arched enough to prevent accidental muting of the B and high E strings.
Then with your picking hand you play each string one at a time from lowest (sounding) to highest as an arpeggio, and most likely let them ring.
Then let go with all fingers except the index finger, play the low E string again with the picking hand and slide the index finger down from the 3rd fret to the 2nd fret without lifting.
Seems to me, if the tuning is standard, that no barre is needed. Instead, play a Gmaj like you would with a barre, but only use the tip of the barre finger(index) on the bottom (fat)E. Then play each string in turn, bottom to top. Then slide the bottom down a fret. My tuner can't find the three notes S,L and I...
Hearing it, all strings are tuned down a tone, and it's played arpeggiated.
As noted in other answers the tuning is one full step flat from standard.
The easiest way to play this is to start with a 3rd fret G Barre chord formation then lift the barre finger so that instead of barring you are only fretting the 3rd fret on the 6th (fattest) string. Then arpeggiate the strum one string at a time. There is not an actual barre used to play this.
In the sound file, I am not hearing the slide from 3rd fret to 2nd fret on the 6th (fattest) string (now D). But the sound file may stop short of that part.
Also, in most tab a forward slash as shown "3/2" would indicate an ascending slide (slide up) and a descending slide from 3rd fret to 2nd fret would typically be indicated by a backward slash "3\2". Although it is obvious that you don't slide up from 3rd to 2nd fret unless you are holding your guitar backwards. My point being - this is a deviation from typical tab notation.
Generally the letters to the left of the string indicator lines on Tab define the tuning of the string that the letter is next to. I would expect to see the letters D G C F A d so I have no idea what E E D I L S means.
My theory is that whoever constructed this notation was operating on a different understanding of how to notate tab than the rest of the world.
