There are probably a few mistakes here. I'm not very good with identifying songs, so please correct me if you find a mistake!! As far as the strumming, its pretty much just like quarter notes. Listen to it on youtube... Some other parts are single strum, where I pointed it out. :) Thanks! Enjoy... Key of , no capo OOOOOOOOOOH! Happy Hogwarts Birthday! Magic wizard birthday!
