How to get the iPhone 5 working with iTunes?

So today I just bought the iPhone 5, and now I'm wanting to download some songs onto it. When I connect it to the computer, iTunes doesn't recognize it at all. Is there any way for me to have it showing on iTunes?
(Not sure where to ask this question, so I left it here)

Added (1). It maybe that, since it's been a while I updated iTunes

Is the phone locked? ITunes can't access the iPhone if it's locked. Maybe your computer is not updated enough to be compatible with an iPhone.

Also, the connection may be broken.
