1. Write down the lyrics to your song. Make sure to include the title of the song, as well as the name of the author (if it's different from your own).
2. Create a new work of art that incorporates the lyrics. This could be anything from a painting or drawing to a sculpture or dance.
3. Register the copyright for your new work of art with the United States Copyright Office. You can do this online or by mail.
4. Include a notice of copyright on your work of art. This can be a simple statement like "Copyright © [year] by [your name]."
5. If you are releasing the song commercially, you will need to obtain a mechanical license from the Harry Fox Agency (HFA). The HFA is the exclusive licensing agency for mechanical rights in the United States.
By following these steps, you can copyright the lyrics to your song and protect your work from being used without your permission.
