What happens when you vote for a singer in American Idol?

The American reality show American Idol is split into three different rounds. Prior to the show airing, auditions are held across the country. For those who are chosen from the nationwide auditions, the journey is just beginning. Once the show airs, the contestants must make it through five rounds before the show goes live. As soon as the live shows begin, fans of the show must call in and vote to help their favorite contestant win.
