To get copyright you have to first compose a song or write a book. Then you can send the information off to congress in Washington D.C. to get copyrights.

To get a copyright, you can apply to the U.S. Patent and Copyright office in Washington, D.C. The application can be assessed on the Internet and you can file it there with the appropriate filing fee. You can find more information here: http://www.copyright.gov/register/...
