Actually you just need to search "how to use itunes" in google, you will get the answer. I have done the search for you. Check the link on wikihow and follow the steps, you will find how to add songs to your phone.

Assuming your music files are already on your computer, in iTunes go to file, add to library, and select your music files. You can select more than 1 file at a time.

After it is in your iTunes library, click on your iPhone (after you connect it to your computer) in the left panel, there are tabs labeled Info, Music, Videos, Apps, etc. Select music, select to add music from your library, click sync.

That's all.
