I find it funny that you're asking about hitting high notes in a forum that is frequented by sports/mma fans. I don't think there are a lot of people here with experience on belting out that Celien Dion style (sp) high note.
If you are reading this then this warning is for you. Every word you read of this useless fine print is another second off your life. Don't you have other things to do? Is your life so empty that you honestly can't think of a better way to spend these moments? Or are you so impressed with authority that you give respect and credence to all who claim it? Do you read everything you're supposed to read? Do you think everything you're supposed to think? Buy what you're told you should want? Get out of your apartment. Meet a member of the opposite sex. Stop the excessive shopping and masturbation. Quit your job. Start a fight. Prove you're alive. If you don't claim your humanity you will
become a statistic. You have been warned...... Tyler
