The fingering is x24442. If 1= index finger, 2=middle finger, 3=ring finger & 4=pinky then you play itlike this: e|---|-1-|---|---|---|---|---|---|---|---|---|--- B|---|---|---|-4-|---|---|---|---|---|---|---|--- G|---|---|---|-3-|---|---|---|---|---|---|---|--- D|---|---|---|-2-|---|---|---|---|---|---|---|--- A|---|-1-|---|---|---|---|---|---|---|---|---|--- E|---|---|---|---|---|---|---|---|---|---|---|---
Can also use finger 4 in place of 4 3 2... Or finger 3 in place of 4 3 2... whichever is comfortable to u. But 4 3 2 on three frets can make the barrey with the index finger bit uncomfortable.. Butvif u r comfortable in the 4 3 2 pattern then it will be easier for u to shift to the correponding 7th chords. ie B7 or BMaj7... Again its a relative issue... varies from man to man..
Dude, this boils down to the bared A-form. I have posted a thread in this forum on this. Search for it. I REALLY tried for the using the 3rd finger to barre 2,3,4 but could not. It depends how flexible your fingers are. For some it works for others it simply doesn't! Try it, if you still cannot barre it after 15-20 days of daily practice, do not attempt it further. Trying the form I suggested is difficult at first but comes with practice. It is difficult than the other E barre form.
