I Don't Understand tab by Jon Lajoie

Tabs

This tab is in standard tuning. You should be able to get the strumming or just make
own variation, so it isn't tabbed. I suppose if you tuned it down half a step, which is how
suspect it is played, you could just play it with D/Bm chords. Regardless, enjoy! Not
much of a difference. :)
