Any advice on singing the natioal anthem solo at a ballgame?
YOU GO!!! :] singing in public is sooo nerve-racking. [believe me, I know]
I suggest always warming up your voice prior obviously. don't eat much meat. that isn't good for your voice. apples are always GREAT for your voice.
relax and take a deep breath before you face the crowd.
dont eat/drink dairy products.
also when you drink water, make it room tempature. if its too warm your throat gets too relaxed and if its too cold your throat constricts
