Copyright for an arrangement
I have created an original arrangement (piano solo) of a song originally written and sung by Jimmie Rodgers and copyrighted in 1933 (and so not yet in the public domain). I can find no sheet music on line for this piece other than a collection of his songs with only the melody line. My arrangement is loosely based on a version sung and recorded by Mary Chapin Carpenter. Am I supposed to put the copyright for the original song on the bottom of each page, along with the original copyright holder (Peer International)? I have given Mary Chapin Carpenter attribution, but is there any need to show her as a copyright holder as well?
