How do I license a new arrangement of a copyright-protected song?

Your new version or arrangement of an existing song that alters the melody or character of the song is a derivative work. You need to obtain permission from the publisher directly to create a derivative work and include that permission when you apply for a mechanical license.

You can use the following databases to locate publisher information:

• ASCAP
• BMI
• SESAC
• U.S. Copyright Office
• The MLC's Public Search
