Short answer
A musical composition is the music and any accompanying lyrics; a sound recording fixes particular musical, spoken, or other sounds. A recorded song may embody both works, but copyright in its recording does not replace copyright in its composition. This distinction follows US Copyright Office terminology, not a universal rule for every creative discipline. 1 2

| Question | Musical composition | Sound recording |
|---|---|---|
| What is identified? | Underlying music and accompanying words | Particular fixed sounds |
| Who generally authors it? | Composer and any lyricist | Performers, producer, or both |
| Must it involve music? | Yes | No; spoken audio also qualifies |
| Is notation possible? | Yes | The category concerns recorded sounds |
These are US copyright distinctions; recording authorship can also involve work made for hire. 1 2
What each thing is
The composition is the musical work being represented, rather than necessarily a sheet of paper. The Copyright Office recognizes that it can appear as sheet music or in a phonorecord. The recording is the fixation of sounds in a medium such as a CD or digital file. Medium alone therefore does not identify which work someone means. 1 2
Key differences
Authorship and ownership are separate questions at each layer. A composer or lyricist generally authors the composition; performers and producers may author the recording. The works are commonly owned and licensed separately, and their copyright rights differ—for example, recording owners do not have a public display right. 1 2
How to tell them apart
Ask whether the reference concerns the underlying music and words or the particular sounds fixed in a recording. That is more useful than asking whether the material is on paper or in an audio file. Its limit: one audio file may embody both works, so identifying the file does not resolve the intended category. 1 2
Where they overlap
Recording a song may create two protectable works at once. Their authors or owners can coincide without making the works identical. The Copyright Office allows combined registration in qualifying circumstances; its registration guidance specifies that ownership of both copyrights must be exactly the same. 1 2
Edge cases
A recorded lecture or podcast can be a sound recording without being a musical composition. Conversely, US copyright law excludes sounds accompanying a motion picture or other audiovisual work from the sound-recording category. Thus, “recorded sound” in everyday speech has a broader reach than this legal classification. 2
Why the distinction exists
The distinction separates the underlying musical creation from the contribution involved in fixing particular sounds. It also prevents one copyright claim from being treated as a substitute for the other. For copyright-focused articles, keep composition rights and recording rights separately scoped rather than treating “song copyright” as one undifferentiated subject. 1 2
Common misconceptions
A composition does not have to mean sheet music, and a sound recording does not have to mean music. Nor does the person performing a song necessarily author its underlying composition: the sources distinguish composer-and-lyricist authorship from recording authorship. These are general categories, not an ownership determination for any particular release. 1 2
Examples
Hypothetical case 1: A songwriter writes music and lyrics in notation, then records a performance. The notation represents the composition; the recorded performance introduces the recording layer. Hypothetical case 2: A speaker records a lecture with no music. The fixed speech fits the sound-recording category, but supplies no musical composition. 1 2
