How to put my music on my new iPhone from iTunes?

I have recently got the iphone 4s and when I plug it into my computer I pull up itunes and click sync but it still doesn't put my music on on my phone. So if someone could please tell me how I put music from itunes on my new iphone i'd really appreciate it.

Try turning the phone off then on again. Then plug it back into your pc. Drag the music from your iTunes to the phone.

Select all music on your computer that you want to put in iPhone> Noe open iTunes> Open 'Music' section from iTunes> drag selected music to iTunes> Connect your iPhone> Backup your iPhone to iTunes> Now click on 'sync'> Wait for while for completing the operation… That's it… You have your iTunes music to iPhone…
