Here's my drop D rendition.
I like to play around with it alot.  This is the basic melody.

e--------------------------------------------------------------
b--------------------------------------------------------------
g--------------------------------------------------------------
d-12--12--9-10-12-9--9-9-7-5--9-9-7-5---12--12--9-10-12-15-14-12
a-12--12--9-10-12-9--9-9-7-5--9-9-7-5---12--12--9-10-12-15-14-12
D-12--12--9-10-12-9--9-9-7-5--9-9-7-5---12--12--9-10-12-15-14-12

Also works like this:

e-0--0-----0-----------------------0--0------0-3-2-0-------------
b------2h3---2--2-2-0----2-2-0-----------2h3---------------------
g---------------------2--------2---------------------------------
d---------------------------->
a---------------------------->
e---------------------------->
