How to sync my Music to my Iphone?

Itunes was working perfectly fine until it said I needed to update it, when I did I couldnt find the thing you click on the top right corner to sync or backup your iphone. It just says itunes store I clicked on everything I could and I can't find how I sync my music.

If you don't have the newest version of iTunes iOS 7 devices won't connect. Three things I'd try though is one be on the same Wi-Fi signal as your computer is and you won't need to plug your phone into the computer at all to sync. Next try to unplug the phone completely and plug it back in to the computer. Lastly turn the phone off and plug it in so it turns on when it gets plugged in. It won't show up until it definitely is connected to the computer by cord or Wi-Fi either. Then which you should be able to click on it.
