All,
It costs nothing to copyright a document or musical piece. All you have to do is a) note that it is copyrighted somewhere on the document; and b) be able to prove that you actually copyrighted the item on a certain date. The easiest way to accomplish b) is to print a copy of the document/music with the words "Copyright (C) 2003 by John E. Doe. All rights reserved." Then seal this up in an envelope, put a stamp on it, and mail it to yourself. DO NOT open the envelope when you get it back from the post office; file it away in a safe or safe deposit box. It will have a postmark and cancelled stamp on it, which is accepted in court as proof of date, should legal action be required at some point.
Regards,
-BW
