What does a parent president of child's band class do?

I was voted in to be the President of my daughters band class. There is also a secretary, fundraiser coordinator and a few others. I have no clue as to what I am supposed to do as President. Please if any other parents have been President of any child's School activities any advice will be very much appreciated. Thanks in advance!!!What does a parent president of child's band class do?
I believe the parent president is expected to fart the Star Spangled Banner at football games.
