Zac played this acoustic version at house of blues but I can't figure it out for the life of me. Normally he plays it in the key of D I think but capo on first fret so D#, and it seems that thats the same key this is in, I just can't figure out why he plays it so differently. Maybe he has a different tuning or something, I have no clue I'm new to any musical theory normally I just play what the tab says. Anyway, I'd appreciate some help thanks!
