I can not transfer my I tunes to my cellphone.I try to transfer my music from my Mac computer to my smartphone. How can I do this?

What kind of smart phone? If for example you have Macintosh osX and an android phone you would need to use something like this to transfer files. http://www.android.com/filetransfer
and then set the phone up to connect to the computer using settings within the application.
