The intro is almost done... here comes the hard part.

After the second C7, the chord progression stays the same (Em,C7,Em,B7) exept the Em and 
B7 split the measure (two beats a piece). I'm sure you can figure out the picking pattern.

After those two (Em & B7) share the measure, it goes like this: (this is the part that 
like it's winding downward)
