A sound recording is a work that results from the fixation of a series of musical, spoken, or other sounds, regardless of the nature of the material objects in which they are embodied. A sound recording does not include the sounds accompanying a motion picture or other audiovisual work. Copyright in a sound recording protects the particular series of sounds embodied in the sound recording. Copyright registration for a sound recording alone is not the same as registration for the musical, dramatic, or literary work recorded. The underlying work may be registered in its own right apart from any recording of the performance.
