Katy Perry Firework Song Video

So the sound is really messed up by my videocamera, i didn't put any sound effect on it. It's just the bad video quality. I'm really sorry. I never had keyboard lessons, i teached it myself so it's not really good. But let's give it a try :D Please don't put any rude or nasty comments, just be nice, okay? BUT be honest. xoxo
