Lots of trumpet players like to post epeen videos of themselves playing ridiculous high notes on youtube, as they all seem to think they are Maynard Ferguson reincarnated. Someone with a high tolerance for pain put a bunch of clips together to create the U.S. national anthem. See how long you can stand to listen before you puncture your own eardrums with a pencil!
