Copyright
Prior to your mastering date, if you have not already done so, you should copyright all of your compositions. This will protect you from any unauthorized performances, copies, or theft of your creative works. All of the necessary forms are available online at www.loc.gov/copyright/ . Fill out the form and ship, along with one copy of your recording, back to the Library of Congress with the required fee (approximately $35.)

Note - Mailing yourself a copy of music will not protect your copyright nor hold up in court !
