All music from Super Mario Bros. 3, 
as well as other Super Mario titles, 
belongs to Koji Kondo.

Standard Tuning: EADGBE

This is the closest match I've found to the end music, 
and while I don't mark it as %100 correct, the style 
captures the "edgy" sound of the original.

I think it's a 4 beat measure, but if you've played 
SMB3 before you probably understand the timing 
instinctively.

Legend:
==> = note hang
p = pull off
h = hammer on

Hard to explain the pacing with the 2nd guitar part, but 
for sure it happens after the first guitar's part plays 
through 2 times. Just sitting down with the video on 
Youtube will help you find the right timing.
