A paper application used to register works that contain sound recording authorship. An applicant should use Form SR if the work contains sound recording authorship and if the applicant intends to register that element of the work (even if the work also contains other types of authorship, such as music or lyrics). If the applicant does not intend to register sound recording authorship, the applicant should not use this form (even if the work happens to contain one or more sound recordings). Likewise, the applicant should not use the form if the applicant intends to register the sounds accompanying a motion picture or other audiovisual work.
