802.6 (F) Setting
Setting usually means the act of putting a preexisting poem or text to new music. A registration for this type of work covers the new music that the author added to the work.
A musical setting of Biblical or other preexisting text may be registered if the music represents sufficient original authorship. In the Material Excluded field the applicant should identify the preexisting text, and in the New Material Included field the applicant should check the box for “music.” If there has been sufficient adaptation of the preexisting words, and if the preexisting text is in the public domain or has been used with permission, the claim also may include “some adapted lyrics.”
