B|---------------------------------------------------------|
G|---------------------------------------------------------|
D|---------------------------------------------------------|
A|---------0--2---2---1---1---0---0------------------------|
E|--0-2-3-------3-------2-------1--------------------------|

B|---------------------------------------------------------|
G|---------------------------------------------------------|
D|---------------------2-----------0-----------------------|
A|----------0-2---2------2--0----2-------------------------|
E|--0-2-3-------3--------------3---------------------------|

then you move it up a string, simple :)
like this;

e|---------------------------------------------------------|
B|---------------------------------------------------------|
G|---------------------------------------------------------|
D|---------0--2---2---1---1---0---0------------------------|
A|--0-2-3-------3-------2-------1--------------------------|
e|---------------------------------------------------------|


e|---------------------------------------------------------|
B|---------------------------------------------------------|
G|---------------------2-----------0-----------------------|
D|----------0-2---2------2--0----2-------------------------|
